have 2 1000w ballasts. i usually run 1 metal halide. and sodium for flowers. i have done seeds in the basement for the last two years. it’s great when there is 1000 feet to snow outside and i can sit under the 1000w metal halides.

but decided to use the space and grow food year around. i have one little tomato so far. i am running plumbing up to the attic so i don’t have to lug 5 gallon pails of water and nutrient up from the bathroom
The point is that many hydroponic operations will be using nitrogen fertilizers made from wastewater and other organic sources in order to lower costs. The use of organic materials will not be eliminated from agriculture, although methods of processing such materials should be done safely. Global corporations will not succeed in monopolizing agriculture or creating source material scarcities for long. Even if sources of materials are highly regulated with gate-keeping laws, open source development efforts can overcome such regimes.
