My plants were about 8" apart in the nft, so only the very ends of the roots were intertwined. When I say they "outgrew", I mean height wise. I can only raise my light on my nft to about 36"
I meant that my nft didn't have a bubbler and now that I have a bubble stone in each bucket, therefore I would think that oxygen deficiency would not be the issue.
The water level the the baskets was about 1" underneath. I was maybe 2" under the baskets in the buckets until I added water today.
I had the plants under t5's in my nft system, and put them right next to the nft. I will add another t5 above the tomatoes tomorrow
