Lol bobo. I knew what NFT meant... just don't exactly know what NFT trays are. I'm guessing they are like rain gutters you put on the side of your house. I kinda have a half NFT system, but I use pipes. You know how my closet has the two levels. The bottom level has dams in it, so the water level stays at around 2-2.5 inches... the top level has no dams and the water is just running along the bottom (nft). Last grow I took the dams out the top halfway through because between the dams and the massive roots, the tubes were clogged and water started running out the plant holes. It didn't do that on the bottom, so I left the dams. So this grow I started the clones in how the water levels were. The top only had less than a half inch of moving water and the bottom ones more of a bath.
I was thinking that I really needed to remove the dams on the bottom as even though the water was 'moving' in the lower level you couldn't tell by looking at it. And there aren't visable bubbles... it's not moving that fast. In my head the plants on the top had the water they needed flowing by and all the oxygen they could want with the open-ness of the tubes inside (not full of water). And I also thought that the bottom level would discourage root growth as the rockwool the plants were in was basically saturated the whole time.
I was wrong. The plants in the bottom developed much bigger root masses, even in the 'bath'. Convinced me that the more RDWC aspect of the bottom level beats NFT for me at least. So for next round I'm gonna put dams back in the top level. I'm not vegging as long as the grow where the tubes became blocked, so I'm thinking that won't be a problem.
I know there was no question... but thanks for asking, lol.
RDWC ftw!!!
Oh, and it's looking like I'm gonna pull about 8 oz out the closet this round. For only running 6 nice plants and going strait to 12/12 I'm rather happy. This next grow I'm gonna veg a week I think. I'm hoping that week of veg will do a LOT for the yeild. I got 18 from the Sour Kush, I think 20 oz is not out of the question this time. Should be getting new clones on Friday. Only a week of downtime... I've NEVER done that. Usually a couple months between. It's nice not changing setups, haha. Don't know what my problem was before changing all the time.
peace
