I bought a AQUATEC CDP 8800 high flow booster pump to run a hpa setup. If a hpa only runs every 5 minutes for 5 seconds why is a accumulator recommended? That doesn't seem like it would be taxing for this pump. The pump is only a hundred bucks and if I can get a grow out of one it would be...

Having a problem with my rdwc grow. Had a problem with root rot. The plants started to recover with new lateral root growth out of the side of the pots. Thing is the roots will start to brown, especially the ones that are not submerged under the water. Is it OK to bring the water level up so...

Whats the aproximate max PPFD can be? The light i'm looking at has max levels of 1565 PPFD in the center 2x2 area hung at 6"s off the canopy. Can leds be placed this close or will they damage the plant? I'm wondering if I should go for the 640 watt model instead for my 5x5 or just get the 800...

I'm about to start a grow using some Mt Clean clones I have from my friend. I'm in a 9x9x10 room but am legally limited to 6 flowering plants. I'm looking to optimize this space for maximum yield so I was looking into manifolding to hopefully fill out this space. The clones were taken on lower...

I just built a rdwc waterfall system with 18 gallon resovoirs and was wondering if anyone knows if there's any benefit to adding soaking rings above the net pots or adding high pressure sprayers inside the resovoirs? Will this increase growth rates or yeild? Thanks David

I have a 9x9 room but am limited to 6 flowering plants at one time since i'm from Massachusetts. I'm looking at a rdwc setup but was wondering whats the best gallon size to grow trees? Would there any benefit in using six 27 gallon storage totes so the roots can grow huge vs 5 gallon buckets...

I found these lights on Alibaba and was wondering what you think in comparison to HLG or fluence lights. I'm thinking about buying 4 of these 800w lights for my 9x9 shed but was wondering if its to much light since i'll need space to move around the plants. Even at 18" above the plants this...
