Hello all. Looking for some help. I built a 4,000 gallon 270 plant RDWC system for commercial cultivation. Running into an issue I didn't anticipate. ​​​​​​Generally in DWC I would change out the reservoir on a bi-weekly basis and re-dose with the proper nutrient ratios for whatever...

Quick update to those following along. After clearing the facility earlier this week of all plant material we underwent a thorough decontamination and sterilization regimen, including the following: 1) Eradication of all plant material. 2) Full cleaning of the entire 10,000 square feet. This...

Ok, so let me begin by saying I'm not new to the game. Been around a while, and while my knowledge is far from comprehensive I know more than most when it comes to growing cannabis (largely thanks to years of research in wonderful groups like this, reading books, hands on instruction from people...

Ok, so I'm confused. I've read over and over again that in order to get good quality flower you need high PPFD at the canopy. Yet I see numerous commercial growers with setups like this. Even at 1,000 watts per light this system can't be pushing anywhere close to the level of light at the conopy...

Ok, I've tried numerous things in attempting to remedy this issue. I'm seeing this leaf development across several systems - organic living soil, DWC, and a top feed coco system. The living soil is getting mostly just water with a splash of calmag since I'm using RO plus a weekly dose of compost...

My DWC system is Killin it. Clones I put in it are three times the size of clones I put in soil on the same day. However, this is creating a problem. It appears that the root masses are now sufficient to block a significant amount of the water flow back to the res. It's bad enough that the...

About 4 weeks into a grow cycle I was doing some LST on an autoflower. It had already started flowering, but only by a few days. I accidentally broke off a branch while doing the LST. I'd heard time and again that there's no use to cloning an auto because there won't be enough time left in its...

Heya all. About to populate a DIY 10 station RDWC with a top feed drip setup. I've seen answers all over the place so I thought I'd take an informal poll to get community wisdom. How far below the base of the net pot do you keep your water level? Thanks for any input!

Good morning folks. I'd not heard of this seed bank before, but they have a really, really great variety of seeds available. Anyone ever used this seed bank? If so what was your experience like? Thanks-

Heya all. Thought I'd share a few pics from the grow as it stands, if anyone is interested in seeing the inside of a commercial operation. Currently running 24 different strains, and rocking about 240 plants. Still a small operation by industry standards, but I've only been at it for 8 weeks...

She's a Gorilla Cookies clone from a vetted mother, but has a different structure from the mom. Not sure what do do when she's not bilaterally symmetrical.

Guys (and Gals), I have some autoflowers under a California Lightworks 1100 that no matter how hard I try I cannot get to reach. I've moved the light all over the place, as much as 4 feet above the canopy for several days. I keep pinning branches outward (LST) but the plants just keep stacking...

Haven't seen a single insect on any of my indoor grow, and zero signs on the plants anywhere of any kind of infestation. Found this guy crawling on the outside of a tent though. Anyone recognize it? Approx 1/8 inch long, and very deep red - almost black.

Anyone use this nute line? If so, any idea how long I can save mixed mutes for? I have some I mixed two days ago but I've looked on their site and around the web but can't find an answer to how long they remain chemically stable.

Ran out of one of my main nutes for today's feeding. I have another nute line that I've never used but could use it until I get a replacement. Will changing nute brands mid-grow screw up my plants?
