I thought NFT is using a slope to provide an slightly accelerate water thru the grow which returns back to
The Rez. I saw the guys verifying slope and side to side level on their tray. As matter of importance the reason they don’t use a filament layer is that they are sweeping water across the bottom of the tray accelerated to cause rippling effects to break the surface tension to induce higher dissolved oxygen if possible. That to me seems more film oriented than running water through 1/4 - 1/2 diameter of pipe which I guess works great for clones. Their weekly documented Nutrient Flood table went from clone to harvest pretty impressive plant growth across the whole table and at the end still just marginal root growth yet great visually veg & bud production at end of grow. I really was blown away by plant spacing! To me it looks like a 12’ ft table with 29 plants ! They grew right on top the feed and drain points as well . Makes me wanna rethink 10 plant in a 4x8.
Heisen stated he thought popping 6 seeds Of a strain at once to find fire.
I guess I’m ass backwards thinking pop 14 HB strains 1 seed each see what
Seedlings Grows and vegs take cuts to veg and flower on the NFT table.
Everything happens just as it is intended & expressed . We choose the how what when where &why by our own perspective. Pop 1 pop 6 it’s all the experience I guess
may your grows be awesome
