Quattro Kush: Flipped to 12/12

This is awesome!!! man look at the ingagement on just that post about the light, I think I speak for all of us when I say you're more than welcome to post about this! I would actually like to know more about this, bugger the guys who gets irritated, this a cannabis grow forum... we post stuff that has to do with growing here and I am well sure this is some golden growing information! not sure if you saw the diy LED thread I made, I know I know, it's not the "very best" out there right now tech used is as basic and minimalistic as I can get without using poopoo brand LED strips. at least I used some samsung LM301H strips. Do you perhaps know how big of a difference in technology and quality of output there is when comparing the Samsung F series strips (LM301H) with the Bridgelux EB strips? I know there are many different strips in each of those catagories, but for argument sake just think of two of the same Kelvin and close to same diode count? my understanding is that the best of the best Bridgelux strips' efficiency is still comparible to the efficiency of the Samsung F series. am I way off or no? What strips you making use of in your builds?

ZxP is 8 weeks tomorrow and the Wedding Cake is 7 weeks. The ZxP is looking ripe for the picking, so I will probably turn the taps off tonight. The Wedding Cake still looks a bit green and glassy so it will keep going, maybe through to 9 weeks. ZxP Wedding Cake My Organic Tent™ is at 3 weeks into flower and is pushing some good flower already. I am going to bump up the Biobizz ratios a bit. I have been alternating between feeds and fresh water so far. I am impressed with the results of the Biobizz nutes.

I suppose one needs to distinguish between breeders and seed banks. These further split into seed producers or selective breeders, and seedbanks that either stock genuine breeder stock or bulk white label Spanish gear. Plus so many nuances inbetween as the industry starts taking a solid form.

I'd assume they would be fine as long as they are similar ballast types ie they are both digital ballasts and you set the Backline ballast to the correct wattage. Those Lumii ballasts don't look like traditional LED drivers. Lumii also sells plenty of other stuff that requires traditional ballasts so it makes sense that they would develop an LED that you could just replace your HPS setup with without having to also replace your ballasts.

I didn't know If I'd be breaking forum rules or just irritating everyone by posting off-topic. But ye, it's the first shipment of my lights that I'm currently making par charts for. Having to take a break after doing the 90cm x 90cm size, my lower back is so sore. @Prom is a super nice guy, he let me use his quantum sensor. Thanks again to you sir, tip of the hat!

Hi all, Just wondering about different ways to keep Tent up to temperature in the night when lights go out?. I've ordered a RAM fan controller box to start with. 1.2x1.2 tent and on slow speed the fan seems an overkill sucking some nice 12°C cold air at a fair old rate!. I've ordered a 400w Desktop fan heater and will couple this with a separate thermostat. The fan will be placed with back near intake. Will update findings in 2-3 weeks for anyone interested. In the meantime, if anyone has any other suggestions to keep the tent warm I would be grateful. Panel heater is possible????. Also,........ what is the coldest temp (at night) that the plants could handle?. I believe 24°-27°C is the ideal temp-----in an ideal world!. I'm running everything on Solar so big wattage heaters are out of the question. Setup; Mars tent, led lights, ram 150mm fan. 2 fresh air 150mm inlet feeds.

Finally convinced a friend to upgrade from HID, helped him build a LED qb bar light. He was thinking of retiring the HID for many reasons. replacing shit the whole time. electricity consumption. heat.... told him if he puts out the cash I'll source and order the shit for him, recieve everything and when time comes to slap it all together I'll just need a hand, he just needed that last nudge and so it begins! I think I was more excited about the build than he was! He's got a 1.2m x 1.2m x 2m tent, so we basically copied the 4'x4' example design on LED gardener, used the Q series samsung LM301H strips in 3000k. First things first, size of the tent will determine the size of the frame that we build for the LEDs. Work out how much Aluminium strip we gona need. Source local aluminium extrusions. This was the only profile available in bulk on the day, we didn't wana wait, so we planned around this. You can work with any profile and have any extrusion company roll out the profile you want at the lenght you want. Easiest part of the build. Having the aluminium, knowing how you can lay strips on the extrusion profile you can use this information to spread out the LED strips as much as possible so there are no fluxuation areas. no need to raise the hight of the light to get better coverage which would mean loosing intensity. no need to have to have certain height requirements for best output, because you don't have excessive heat coming from the light and not ALL the light comes from one spot and then has to spread, instead you spread the strips out further so you can bring them closer to your plants without having intensity issues. also the configuration being a bar style light you wont have issues with the fixture heating up at all. we run the light for 18hrs, shine laser thermometer on the frame from below the light source, got 34°C. 5cm away from the light source on the aluminium frame we got 29°C and at leaf surface at 15cm away it was room temperature... will get a apogee under the light asap, if anyone wants to follow up on that. now, the layout.... knowing what amount of strips you gona use and the size of tent you have to put them all in, you build a frame that can easily fit inside the tent then just space out the strips as much as possible. Next step was to cut the aluminium to the right lengths and clean up the edges. Along with the aluminium for the frame you'll need the smallest pop rivets the shop has to offer and a aluminium drill bit same size as the rivets. Now, slap the frame together. 2 long slats get a tine 45° corner cut out the flat so the fin is still in one peice, make a small cut on the other side so you're able to bend the aluminium without it snapping. grab a big 90° angle, make sure you have 2 x 90° angles. lay them together making sure all 4 corners are 90°, throw some clamps on, drill right throug the 2 corners that meet and pop them together with the rivet. Now grab a electrical junction box to hide all your wire conections, use the junction box to space out the aluminium stips, making sure you can fit enough strips on to accommodate all the LED strips needed. using a pensil, mark out where the aluminium strips lay and number them 1 - X and mark the frame with numbers corresponding to the strip that goes there. drill holes in all the aluminium strips where you need to pop them to the frame, put them back on the frame using the numbers to see where each one goes, use the hole im the aluminium strip to mark where you need to drill into the frame, drill all the marked points, lay them out, pop them in. here is what ours looked like at this point. BOOOM!!!!! got a digikey box in the mail It's all there and all undamaged! Now that we have the driver. it's time to build a bracket to hold the driver in place. same like we built the square for the frame, just a small one, like this.... -note the corners driver still has some space to move around, but sits nice and snug, we ended up putting two small self tap screws throug the screw slots at the bottom of the driver to hold it in place, didn't get photos of it, but did get photos of how we attached the bracket to the frame, using two small peices of aluminium and popping them onthe the fins upside down we now had a flat surface to mount the bracket onto. like this... Here's where we're at now, Time to make this big boy easy to hang! 5.5mm threaded hooks with 2 self locking nuts, one screwed all the way to the top and one to hold it in place. Time to slap on some double sided thermal tape, this tape can hold up to 60kg at 120°C.... or so it sais..... so it should work! AND YOU KNOW WHAT COMES AFTER THE THERMAL TAPE!!!!! FUCK YEAH step by step getting there!!! now for the fun part, the wire nightmare.... luckily I have OCD-AF and find great therapy in wire management! we also quickly reaslised that we're going to need more than one junction box, easy peasy, the driver has 2 outputd so slap another one on the other side of the driver and have half the wires one side of the light and other half on the other side. I got so carried away with finishing up the light I never took a photo of what the wiring looked like when I was finished, but that was by far the most satisfying thing about the whole build. when time came to plug the bitch in I was just focussing on the damn light. here she is in all her pride and glory here she is lighting up the tent, and this is where she'll be for the next 10 years probably. hopefully. it's a 1mx1m frame in a 1.2m x 1.2m tent - fits perfect. those intetested in the wire work if you wana see what it looks like I'll lower the light to take a couple photos, otherwise this last photo will show just how hidden and tucked away everything is. not one loose hanging wire, no excessive wires, no bulky no extras. Now to answer some questions..... LED Strips - R3831 Driver - R2300 Import Tax - R1500 Aluminium - R600 Thermal tape - R200 Ratchet ropes x 2 - R300 Those are all the more expensive parts of the build, the other stuff like hooks, wires, wago connectors, cable ties + hooks for wire management, pop rivets all those things gona work out +/- another R500 Let's say all in all = R9231 that's that. buddy got 3 x Peanut Butter Breath cuts and 3 x Canna Health Genetic #21 cuttings under that light, potted in FF premium classic, will post few updates here as things progress. have a good weekend all!

Very nice shape!

Should update here, but things have happened as I thought they would, lazy gardener mentality, so these plants have become quite an annoyance not because of anything really but because of the street lights causing all the plants to slow flower down as well as revegging seen on the one GG4 clone, other control one going on with flowering, So they have still be getting nutes but not as often as I was away, they got a 0,5ml p/L dose before I left them. you will notice I moved all the plants out on the astroturf, next to the shade cloth, the street light in question is in a south west position, so they in a more shaded dark place at night. At the time I moved them I thought to go and have a look at the weather to see when’s the next earth watering, pm doesn’t stop for nothing anyway, let’s see if we can fight all battles ☝ Gg# clones below Sugar widows below sugar widow control buds sugar widows experiment buds gg#4 experiment buds revegging Gg#4 control buds the situation

yeah I fully agree that the samsung diodes paired with red diodes will be the winner, but I am on the same page as you with the Lumii light not using the samsung strips, otherwise it would be the first thing they wana let the users know. I don't see anything about the brand of strip used. that concerns me and leads me to think it's bridgelux strips or something. in which case I don't think that light is that much better of an option than building a DIY with samsung strips and having the option to add red diodes on your own will. I am trying to figure out if that Lumii is really a better option or not. I mean if I have a DIY LED without red diodes that doesn't mean it has to stay that way and if the other option is a light around the same price but it's got weaker diodes just with red added, then I will stick with my DIY being the better option.

fok me, this a fan leaf bottom right covered in frost? you got your hands on some very nice phenos there! your organic grow is looking this is not your first go at organic hey?

A good consideration indeed @Naughty.Psychonaut... IMO first prize is going to be those LM301H diodes paired with the red 660nm diodes. These red diodes definitely seem to be making a huge difference to flowers and the LM301 are considered the best diodes currently so a mix of both should be best. I seriously doubt that the Lumii is using the LM301 diodes but if they are then that has to be an awesome light. Here's another question, If my ballasts are Backline and not Lumii, would they still be able to operate on the 720W Lumii LED.? I'm guessing that they might but surely the manufacturers want users to stick to their product and would have designed the LED to be compatible with their ballast and not others. My guess is it could work but probably not as well as it should. Also those red diodes found on lights are not manufactured by Samsung. When those Lm301's found their way into grow lights they quickly became a game changer. Do you think Samsung might produce their own red diode that might become the new standard for grow lights again? Peace ✌

Nice set up bud, I would suggest a panel heater. If your fan heater is still in the box. Possibly take it back and get a panel heater in there, you can use a sonoff to regulate the temperature switching it on an off to keep the temp in the desired range. I have found this to be the best method to warm up the tent during these times. Also possibly let your lights run during the night to keep the temps in a better range. Goodluck.

The big fad right now is additional UV diodes which, frankly, aren't true UV and plus, people aren't even aware of the dangers of true UV and how to protect yourself when using it. The commercial LEDs are definitely getting nicer, and they could be making them cheaper still if they weren't trying to stuff every gimmick onto the boards.

Dqxslurri: Day 26 of flower. Quattro Kush: About ready to flip.

So. Everything is looking good. I have 4 Bobby’s Widow u and going. I still have hope for the 5th one to join the club. The 6th one’s tap root had issues.

Yes when Led was still kak expensive it was worth building your own lights. But with Lumii Black 720w coming into The market it will be hard to build something for cheaper than that.

We're in the final stretch here! Past the 8 week mark, watching the trichomes for chop day. I'm loving the colour this cold weather brings. Seeing the 2 strains react in their own ways to it is interesting too! The Bananium has me really excited at the moment, rather sad though as I wish I had let this girl get bigger. I won't be harvesting much Bananium from this tent, it was the smallest plant in the beginning and could not compete with the stretch of the Deluxe Sugarcane. Overall I'm happy with the turn out. Growing for myself means I get to smoke all this beautiful bud, and boy am I happy with the product! In case you're wondering, the smaller dark plant on the left is Bananium, the other 3 are all Deluxe Sugarcane. Very easy to tell the difference in pictures. Let me hear some comments, things I could maybe improve on for the next grow, I am still such a noob at this!

@Naughty.Psychonaut, yea probably right, but it's only some of them, and not much I can do about ot now. It might be the medium, or the fact I use same feeding throughout veg and flower. The crystal's are looking good though, and no signs of PM, which is my main goal for this one. I'll add a couple of blocks of coco to the substrate for next grow, and maybe just use the greenhouse powder on veg. Need to try some of the 'flower power' nutes now available.

Hoooozit guys. Thought I would share some final thoughts on my last grow. All the nugs that were exposed to direct light came out extremely dense and hard. Very happy with the outcome. I did however realize that I need to clean up even more. I came out with alot of fluff aswell. Have never experienced this kind of fluff. Underdeveloped nugs that look like leaves with trichome on it and that is it. So we learn. Drying was abit difficult with space. Did not expect so much but we managed to get them hanging with an average humidity just shy of 60%. We had big rains the first few days of harvest but I was not able to stretch the harvest longer than 10 days. Still came out very nice. The following are the numbers I got off the plants. I harvested each set of 4 plants under each light seperately to try get a better understanding of the two different lights and what product I get from it. I will name them "DIY" for the light I buildt and "KING" for the bought kingbrite light. DIY Prime Nugs: 312.7g Fluff: 353g Trim: 326g KING Prime Nugs: 437.4g Fluff: 268.2g Trim: 331g So as you can see from the numbers there is actually a huge difference between the lights in producing dense nugs. I have a feeling the kingbrite having red diodes is what makes the difference. I might actually buy a couple of Bloom booster lights from Kingbrite to supplement my DIY light. Will see. Through the weighing I just learnt what kind of cleaning up I am going to do in the future. Overall I am still happy and having 750g of proper prime nugs. Both batches were also trimmed with a trim bag and was also interesting to see what the bag dig with the fluff. I am defenitely aiming to get 1000g in the next harvest because getting 1g per watt would be very good with these LED lights. I would be over the moon with 1000g. (Just before anyone thinks I smoke kilos of weed, this gets shared between 3 people that are all heavy smokers ). Over all I am very happy with the harvest and how it came out. I give it a 10/10 for bag appeal. The flavour is nice and fruity, not a specific kind of fruit but like a bowl of fruit. In the flowering stages it reminded me of the smell when you walk into the smoothy section of a fruit shop. I love it. I didn't use a carbon filter this time simply because it was not the over powering smell I would get from other stanky strains. I enjoyed this strain so much that my next grow will be half of it and the other half Cheese donated by @John Stonedwell. Super excited for that grow. Will just add it to this diary. Unfortunately there might be a mistake that was made in the transplanting when I was not available and I think we might have the Cheese and Mango mixed under the scrog. Not a problem though. Will still count seperately. Thanks for watching and hope you enjoyed. Here is some nug porn.
