Prom

Do you measure your fertilizer, when you give it to the plants? Or do you just guess how much to give? I think growing went into the next league with measuring your light and applying what the plants need and not what you think they have to get. We measure water, fertilizer, time to grow.. but not the amount of light we give the babies... why? Is it worth it to spend on a quantum flux meter? That is your own decision.. I grow for that long, I know I can grow.. but how much I get out per sq or watt.. that is my challenge. I wanna hit 1kg per sq on every harvest I do. Would love to see how close I get to 3g/watt, if I go as perfect as I can go. I learned a lot.. really.. more than in the last 10 years, just by using a stop watch to clock my lap times. Without, you just guess your lap times.. I post one pic and that explains all.. Same strain, same time glassed.. different light intensity. 250mmol are recommended by Apogee.. what a result with just different light setups. No, you do not need a quantum flux meter to grow a plant.. if you wanna reach the limits.. yes, you need one. The plant with more light.. didn't perform better.. wuuuppppssssss.....!!!!!!!!!

Week 10 has started Day 1 Week 10 And here is week 9 in motion.. dark times are Eskom load shedding related. I bumped the tent from the outside.. cam go moved a little, you will see.

Fems, i wouldnt go september in ct, just because of the temp drops (or you work indoor first). Beginning October is a good time to start. Just keep that soil warm till they reach veg. Autos, a bit different approach. Depending on duration.. seed to harvest, plan ahead. Beginning Nov is a good start for Autos. Cold is gone, and you hit peak sun duration over your growth. Outdoor autos, add at least one, better 2 weeks to the total grow duration. You should end with harvest Beginning Feb.. and have no seeds in your buds.

Gorillas UN-Burbled ^^ I turned the light off and made a few pictures to see how they are doing. More pure water ^^ is a bit very green hehehe but rest.. aren't those sexy bitches?!?! Still week 9

See, the quantum flux meter is 500 meter away.. isn't far, but still.. I don't want to go and get the meter every time I do a change on the lamps. With a dimmer.. you need a meter or you have zero ideas how far to hang. Hence.. 100%. Yes, the driver will run 100% but is also designed to do that. They don't get hot at all.. like the heat sink.. hand warm. I have my boards running at 100%, I do my measurements and write em down, once borrowed the meter. So all I have is a piece of paper to have the right micromols on the plants. Saves me the 10k Rand quantum flux meter, and just have it to measure each lamp every 6 months and see how much they lost and adjust distance to hang. Knowing your lamps is a huge part of success. And is also a 48v driver.. just has 120w max capacity.. just perfect to run one board. If you wanna use a dimmer.. you will not get around a proper meter.. or you will guess your way to each harvest. I like my growing more uncomplicated.. but still try to achieve perfect conditions.

HPS written on it.. When we talk light, HPS is and will stay for a bit the target LEDs try to achieve. Those are the best lamps in my opinion.. they just eat your wallet dry in no time. HPS is for the rock stars of growing, not giving a rats ass about the amount of money they invest. Have guys in Europe reaching 1.5 meter and more on Autos with HPS systems... my LEDs can't do that, No Sir! But I also prefer my autos not as tall.. so zero complains from my side.

The smell is getting very much noticeable when you enter the room.. rest. I clean out the old leaves and keep a clean pot.. that is all. Day 4 Week 9 Feeding is on 4/4/4 (Grow/Bloom/TopMax)

HPS is still the thing to beat.. they are just very very hungry. g/watt they lose against LED.. if I wouldn't have to worry about electricity cost at all.. I am rather sure, I still would use HPS lamps. They are great but very expensive to run.

Bit hard to see what it is drop the popped seeds directly into the final pot. 10 Liter pot filled with FF Green bag will do the trick. You do not need Root Juice.. I just waste some cash with it. When you once run into it.. get a small 250ml bottle.. lasts for a very long time as you only use it first week, then stop. More important is BioBizz Fish Mix.. that is the steroid version of Seagro Before I would use Seagro I would go Guanoflo, has way more N.. that Seagro bottle wouldn't last to long.

I have my own compost to mix 50/50.. but a friend is a bit more lazy and just uses the bags.. my way is cheaper.. not better. Have to be that honest too No difference to me.. he has some White Widows finished end this week. Hehehe Autos.. what else.. one has a arm thick main and is 50 cm long no, no differences

Na.. don't worry.. is not really a hot mix. But a great buffer for all. Main nutes still come from BioBizz, but is a very fluffy mix. With Root Juice, they grow very fast in the first 2 weeks. I always reach 5 finger leaves end week 2.

That is the shizzles! This soil is something of the best SA has to offer for growing..

The H is the more expensive version.. so you should find a cheaper version with another board soldering company using the B version of the diode. If you do not buy a tested lamp.. you need to read properly! You want IR and you do not want UV inside your board. 3000k or 3500k version.. is a bit choice and preference. When they mention UV.. look somewhere else, has nothing to do in a grow light. They have as selection: 3000k 660nm ... you go there.. or I look further.

I use Freedom Farm Premium.. drop the seed directly in it.. they love the shit

Put in a cart board box and hang a light inside, close up, blanket around if needed, just don't cook it . I have a rather stable temp in my grow room, so I do not have those troubles

If they have the IM301B on, you have the right diode.. check to take the 3000k 660nm version and should do what you want it to do 2 of the 288 QBs would replace a Mars 144 and draw less (for a 1.2x0.6 area). So my Gorilla Burble is beaten.. I don't even test that hehehe 240 watt is less as the 270 the Mars 144 draws. But I put the Sweet Seeds in once here for another no effort grow.. and run it with a QB setup to prove my point or prove me wrong

Check that your boards are v3.. newest generation. I can't really read that site, my browser hates it somehow

Can tell you how I do it.. doesn't mean this is the only correct way is just one way. Drop the seed in a glass of hand warm water (i use BioBizz Root Juice already here (4ml/L) Keep it for 12 hours in the glass (dark and warm), avoid leaving it longer then 12 hours swimming.. sounds funny, seeds also drown. If it popped in the glass.. put on a smiley face. Put the seed in the final pot, about 1 cm deep. Keep it warm! (25 degrees sexy) If it doesn't pop in the glass, I like to plate. Use 2 dinner plates and 4 sheets of kitchen paper. Wet 2 papers fully and squeeze the water out by hand. Should be moist, not wet. Put on plate no1 and cut everything hanging over the plate off or fold inside. Have a 1cm gap from paper to outside of the plate. Do same for plate no2. Put your seed(s) on the paper on plate no1.. if you put several, leave a gap (2-3cm) between each and do not handle with your fingers.. find a way in any case wash your hands before you handle your seeds.. best non powdered medical gloves. Then put plate no2 upside down on plate no1.. flying saucer style. Dark and warm spot like the glass. Some prefer to let them grow till root has 2 cm.. I plant em when they pop. They need WARM!!!!! They drop ONCE below 12 and you have issues.. below 10 is bye bye seed! Keep that in mind!

Is a bit the question what you want to do.. my Arduino not just handles the dimming of the lamps. I use it for climate control and is connected to a few 240 relays handling 1 8 inch intake and 2 6 inch out takes (one in room circulation, other vent under the roof with a carbon filter connected). The system just reads the sensors (humidity, temp and light) and activates the relays depending on the settings (light would send me a alarm message). If you just want to dim, you need a simple regulator https://www.takealot.com/dc-dc-step-down-power-module-using-lm2596-1-25v-35v/PLID60539879?gclid=Cj0KCQjwgJv4BRCrARIsAB17JI6r7I8Z7x3U3HDNgpHkTGkQjEVXl3JQoeDDiMeCBggo01lnrDTZSMQaAu12EALw_wcB&gclsrc=aw.ds And connect it. The rest i can write you the script or you will find out, is rather simple. The module also comes with a script.. if you want a keyboard or a knob to change the settings, that is your choice. Is a very simple language and you find for any issue help online. (I have a little advantage here, I worked as a professional programmer, when I was way younger)

digikey had free express shipping at the time. Aliexpress goes per weight.. so was cheaper for me to order from 2 different suppliers. If you buy just one QB 288, do NOT take the 240 driver, take a 120.. other way you waste way to much energy or need a dimmer. The 120 works perfect and the draw is correct. The 240 draws way more as it just tries to squeeze everything inside the board.. one reason my boards were way to hot. Now.. not even sure I need a heat sink, hand warm. So select the driver matching your boards wattage. 1 QB288 IM301B/H - HLG 120H-48(A, B or AB) 2 QB288s - HLG 240H-48(A,B or AB) If you do not want to use a dimmer, just don't connect one and it will run 100%, works on all three driver versions A, B and AB. But you still have the option.. I go with B usually as I like to connect them to a Arduino system and dim from that source.

There are many way better growers then me on this site. I ignored Autos for 3 years.. autoflower.. what shit is that!? hehehe But when a professional grower tells you.. "mhhh Cape Town, you should put some Autos outdoor, that should end great with the amount of sun you guys have. First batch has also no seeds." The second part made me listen.. i tried them and cursed myself not to have given those babies a earlier chance to prove them self. I had one more grow of Fems beside the Autos.. then decided that I actually enjoy Autos a lot more.. and we talk miles I am over snipping and binding. I want to grow as relaxed as possible and get some results. The Gelato.. that weed changed all my books. And my tracker moved, post office is catching up.. 100 42FastBuds Gelato Seeds inbound, passed customs already that should keep me happy for a year might sell some of the beans I don't need. No need to let em get old.

two are not drinking as they should. Noticed on one plant very fine yellowing on the tips.. my inner feeling told me to give them a pure water feed today. Royal Queen seeds say is a 8-10 week plant. Also shows you, that you can't trust those numbers, very sure the plants will need 11 weeks. But 8-10.. I select my 8 week feeding sheet that one takes no prisoners. I should be scratching the limits here @afternoon blazer I don't do this to show how great I am as a grower.. I actually am not I have more respect for the guys getting a 600g harvest out of a single fem. I grow for over 30 years.. and all I want to show is that Autos are a new breed to deal with. Those hardened Nordic suckers have a unbelievable nute distribution. They go way more berserk with flowering, as they usually have way less time to do their job in nature. Due to ignoring the Photo sensitivity you get a lot of energy into the plant in a very short time.. and best is just the fact: don't disturb Autos! We did 2 individual tests for defoiling. In both tests we selected the fastest growing and strongest plant and made a clever defoil.. open the light to the buds, not touching the other fan leaves. Both tests had exactly the same outcome.. the once strongest and biggest plant had in both batches at the end the lowest yield. And was never second last or middle.. dead last. Undisturbed, they seem to perform best.. so if you like to grow but don't want all the training snipping, binding, folding or what do I know.. go Autos they yield unbelievable well for the size they form.. just keep them happy feed and have the right climate. Mine is never dropping below 19 and not over 22.. love winter indoor growing

Week 9 Started... and they also start to put on some smell now ^^ Day 1 Week 9 And week 8 in motion. The cam and the fan started to collide. And then the less important had to go ^^ .. the Fan hehehe So sorry for the cam moving but the fan did that. Also nice to watch the plant relax after the wind disturbance is gone.

What you feed them? first guess, due to the very dark green color.. nute burn

Is on hold... I need other drivers for the single board lamps. Right now the QBs run higher wattage at the TS3000.. that isn't helping I want same yield, lower wattage. So a little delay..
