Im a little ashamed to admit, scorpion diablo were the fixtures I had in mind. I will wait on a light upgrade until I burn out a fixture and somebody runs and proves LM301H Evo diodes from the tip bin. As far as Recharge I wanted an easy means to replace the rigamarole of compost tea. I believe dry soil is the enemy to your microbial colony and fabric pots make it necessary to continue to promote the good bacteria. Upsizing to 7 gallon fabric from 5 gallon should help the soil provide a better home for colony life as well.
