At a local garden store here. I would rather use 'organic'...but it would be too high in protein and start to smell awful.... alas.... It's called Peters Hydro Sol. To one gallon of water you add 1 teasp. of fertilizer = 1/2 teasp. Peters, 1/4 teasp. calcium nitrate and 1/4 teasp. epsom salts. After the veggies are done...use left over water/fert in the garden and start afresh. I think that PDF file will blow you away...growing crops on 4' x 8' sheets of plywood in beds 4" deep!!!!
Would love to know what you think. Hey the kids could have their own lettuce farm for the market!!!!!
