I purchased some Gen 3 strips and later some Gen 3 Thrive. And now I need to add to my build and cannot find any vendor who sells them. Digi-key and Future Electronics used to have them but now they are special order only. Does anyone know other sources? And what does that say about the...

I have a 6 light flower room. Because my veg room is too small to grow all the plants needed for the whole room I split the room in half and run 3 lights first and then 4 weeks later start the other 3 lights. I'm considering expanding my veg room so that I can have all plants start and finish at...

I'm trying to make a cheap seedling light with EB Gen2s, which are nice and cheap, but the only drivers I know will work are the expensive meanwell drivers. Looking for recommendation for cheap driver.

I cannot figure out what is causing this poor growth and leaf symptoms. System - top-feed course coco. Pot size - 2.5 quarts Nutes - Jack's hydroponics PPM/EC - 750/1.5 PH - 6.0 Water temp - 64f Room temp - 80f RH - 65% I started my feeding from rooted clones with a 6 oz of nutes every 4...

I'm at my wits' end. Trying to figure out what could be causing the plant problems I am having in veg. The only things that are different really is the medium (course coco core) and the lights - EB Gen3 4k CRI90. Here are my details: - Nutes = Jack's hydroponics - EC = 1.5 - PH = 6.0 - water...

Concerned I might have got Russet mites in my coco, but it seems unlikely. I'm using a compressed block coco that has been pre-washed. Wondering how common it is for people to find nasty bugs in their coco? Would this come from the factory, or the store that keeps their coco near their soil...

Just found out the deviating news that I have russet mites in my veg room. I have plants grown out from seed that I put a lot of work into and I was getting ready to put them in flower, so it is painful to have to destroy all of them. Does anyone have experience with actually winning the...

I'm trying to setup a top-feed system that uses a rez that is not lower than the plants. Some flood and drain systems like Greentree do this by using a container (bucket) and small float valves (water level valves), that then pump the water back to the rez. The plant buckets are connected via...

I've been reading up on the effects of spectrum on Marijuana plant growth. Much of what I'm researching pertains to Flower cycle only, like the Emerson Effect, End-of-Day, and UV for increased trichome production. But I need to replace a couple veg lights so I am looking at strips for that...

I figured you hydro guys (DWC) would know about water temps as it is so critical for you. I know lower temps have higher O2, like 68 is ideal I believe. But if you get much lower like in the high 50s will that cause stress to the plant?

I'm looking at building a veg strip light that will cover a 4x4 area. Here are the options I'm aware of, if anyone has advice on other options please let me know. Bridgelux EB Gen3 Thrive - more expensive and less efficient than Reg Gen3 but fuller light spectrum - CRI 98. Bridgelux EB Gen3...

I'm doing top-feed coco in 1 gallon pots. I find the 1/2 inch tubing to be a bit big to make a ring out of for my pots. But the 1/4 tubing gets clogged too easily. And the emitters don't give an even distribution to the whole plant roots. Anybody have a top-feed system that really works well...

I'm growing top drip in coco. Jack's nutes at about 900ppm, ph 5.8. I'm still trying to get my drip system setup so until that I'm just hand watering once a day. Is this an underwatering condition?

I'm wiring 10 x Gen 3 strips. I'm doing series wiring in pairs, so 5 series, then parallel wiring the 5 pairs together. In the image, is this correct, that I can't parallel the positive strip if they are in series on the positive?

I'm going to be running 10 EB Gen 3 2 footers, with the 185H-48 in 2 series of 5 parallel. This gives me a sweet spot of 7.8A at 19.15V and about 150w. I've heard that if you run your driver at lower wattage efficiency goes down. Do I lose a lot of efficiency running a 185w (actually 187.2w)...

These are seedlings that are now about a foot tall. 1 gallon pot with roots organic soil. Watered only when pot has dried down. Basically been watering every 4 days or so. Watered with plain chlorine filtered water, no nutes. These are outside under shade cloth, the temps are high at mid to...

A few days ago I transplanted some clones into rockwool cubes. And now about 20% of them are showing blotches of rust. PPM - 480 PH - 5.9 - however, I just caliberated my ph meter and it was off so the actual ph was around 6.3. I've researched rust spots, not sure I found a universal consensus...

It has been said that marijuana roots will grow only so far vertically but tend to grow horizontally farther. I recently started vegging in a shallow but wide bucket to give more room for this lateral growth, and the plants branches seem to be growing more horizontally also, much more squat and...

I have some outdoor mothers that I unwittingly let slip into flower, probably only 10 days in, and I need to take cuttings asap. I've read the "how tos" but still have a question. And I've actually tried this once before but it took over a month and ended up only about 25% rooted, so I'm hoping...
