I say quantum boards but they're from China, but they have legit LM561C S6 top bin diodes (3500K) (confirmed with microscope) The picture obviously doesn't show the true brightness of it. I will be adding deep and far red when I have some spare cash for Emerson effect.

Grow area is 240x120x205, currently running the seedlings under a 320 quantum board, once plants are bigger size they'll be running under 1520 watts worth of quantum boards. Running two 6" fans for active intake and will connect a carbon filter when required. I will also be supplementing c02 with a regulator. Will post some pics later this weekend, redoing my light fixture and installing some new acoustic ducting.

Initial stages of my first grow in ages. Blue Berry Kush (Paradise seeds - reg) ( four in the four tray) Bomb Seeds Medi Bomb #1 (the two in the two tray)

I really wish they would stop calling it Dagga, that word is so vile.

I'd be keen to help.

Fourways, Jhb

If that's the case this forum software really needs an overhaul.

What do you suspect the outcome will be? Personally I think the con-court will favor with the state.

It's because your images are massive resolutions, downsample/scale them. Image Width - 3120 Image Height - 4160

How far are the lights?

Yes it was not a negative insane, I remember having one plant and being able to smell it from my drive way

How many carbon filters do you have running? The smell must be so insane. What the hell is wrong with the plant in the bottom left in the last pic ? Looks kinda dead

They're in the final pots. A little worried about whether those 20L pots will be enough for the organics to be honest, especially without any substantial feeding... but will see, perhaps I may have to get some Biobizz as backup. The hydros will be fine. Will be flipping to 12/12 today What are you using to keep your hydro cool ? I've never grown hydro and will be attempting / building my first hydro setup in the coming weeks. All the hydro coolers i've looked around for cost in the region of around 9K...

They're not efficient at all, but they're cheap. So you can literally have has many as you like or just make one in 5mins. Here is a article showing some rates, ignore the mosquitoe related stuff https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2984570/

Yeast+sugar+water + 5L water bottle, tubing, and a small inline valve to adjust the release. yeast eats suger produces co2 byproduct, R85 for bulk active yeast macro for 24packs 5grams, it'll last you a few months

co2 to any grow is beneficial immaterial of the size. I'm sure you've read articles on the subject so I wont copy and paste but they all over. That being said you can easily just build your own generator for like 50R.

You'd need to get it at around 1000 PPM. You'd need to calculate the volume of your tent, then the release pressure of that bottle in order to verify that are indeed getting it to the required concentration. For your size tent which looks like 1.2x1.2 ? I'd go with one of the mycobags they last 3/4 months. Those bottles are a bit gimmicky in my view and only last for two weeks at 250R a refill. i'm busy setting up a regulator with a bottle, however due to the costly nature of co2 monitors ive had to work out the required release pressure along with the timing intervals in order to compensate for my extraction fans. Ideally a nice co2 monitor would be awesome, but at 245USD meh..

Sent you a PM.

Yes you can run the ballast at that, I did a few times (it was mine )

Hate to break it to you, that is where HLG originally got their QB boards manufactured, by Bava or Hansion. Sure... I think you misread. I was saying that a new production run of QBs wouldn't be a good idea now. It was a good idea when I did it in June 2017. But now everyone in Shenzhen has caught on, and is sitting on stock of HLG clones, ready to sell. I would rather put my effort into designing something that you can't get from China (yet). In other words be ahead of the game, which you have been. Have you looked at mixing cobs with some diodes? Sent from my ALE-L02 using Tapatalk Mixing cobs and strips is common, even adding some far/deep red for emerson effect.

Do yourself a favor go to builders, buy some metal tubing of your choice, work out the wattage you want for the room, then buy some of these https://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SI-B8V521560WW/1510-2221-ND/6624005 and then buy a couple of mean well drivers to power them, depending on what wattage you want to run each strip at you can build yourself one heck of a powerful light for very cheap in comparison to these other products, you could even go for the influx (new) https://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SL-B8V7N90L1WW/1510-1357-ND/5958916, more efficient. You'd most likely need like perhaps 4 maybe 5 for your grow area? So that's like 1730 for the strips, then just find the mean well LED driver you want. This way you can build the light to your exact needs and add extra if you want. Thanks this is great advice. I will go do some more research on this topic. I should add digikey will deliver with UPS World saver I believe which is too your door in a few days, purchases over 2K is usually free. You could build yourself a 500 watt LED (run each strip at 100 w), get U-Channel from builders, mount the strip the flat side of the channel, you could then also get some thermal conductive tape to fasten the strip to the u-channel, get some smaller heat sinks if you want to place inside the channel, even mount some fans on the ends to create an active cool environment, your imagination can wild. You'd just need to see the efficacy vs power ouput, I believe some run them at 75% as the sweet spot, others burn them to hell at 100 watts or more if they can handle it. A meanwell 600H-54b (https://www.mouser.co.za/ProductDetail/MEAN-WELL/HLG-600H-54B?qs=5pLaOnqdcwNCvIm%2fbJMCow==) is about 211$, 11.2A ouput. My new light im building runs off of 3 600H-48B's

Two of these in that would be perfect https://fluence.science/store/ray-series-led-grow-lights/ray22/ - 370 $. That's the problem with half these stores in SA, they advertise stuff but never have products. I've resorted to actually just importing all my grow stuff, local stuff is just so sub-par. Hydro shops still punting shitty burple leds for 10k lol.

You welcome to move it. I've done some more reading on the SANlight and their optic lenses is really cool as it doesn't create shade. I hear those lights can easily last you 10 years plus. Just the damn price Which one are you looking at? For the price of this model : https://hydroponic.co.za/hydroponics/sanlight-p4w-led/ I'd rather just go for a fluence ray 44, I have two on the way from the states.
