Harvest a Pound Every Three Weeks! | Rollitup
Outdoor growers are heading inside now so I thought if might be a good time to start a thread on how you can harvest a pound every three weeks from a 7x8' closet. I'll take you through my process from start to harvest. What is different about my system vs. others? 1) 3 separate Aero/NFT...

I used 6" PVC because the fence post covers were not available, I do recommend the post covers the round tubes are hard to seal around the net pots, I use foam weather strip and change it every grow.
Totes should work fine, be sure to locate sprayers between net pots not directly under them. I use a 35 gal res because that is what I found at farm store. I use the green color sprayers they never clog red ones do. Put a sediment filter in the line feeding the sprayers. Got mine at hardware store in plumbing section at well pump area.
Be sure you will be able to get to the drain hole inside. The roots will will will clog it sooner or later. Gently pull roots out and relocate them. I pull the ends off my tubes every 2 weeks and clear drain hole.
