My design has two tubs that drain by waterfall back into a central reservoir...I'm wondering if the entire Res must be covered/lightproof??? I will be using Foxfarm Grow Big, Big Bloom, and Tiger Bloom.... My water is from the tap. PH7.8 and using a TDS my baseline PPM is 700... I'm not sure how bad that is.. After soaking my Hydroton in PH5.6 water for a couple days and it still seems to be raising the PH by 1 point per day...

Still waiting on germination.

The Brick around town is beginning to get on our nerves and we figured growing our own would remedy that. Budget is tight, so everything is non-prefabricated except for the lighting fixture. Frame is all 1x4 pine $30 Tubs are both rubbermaid I believe. $20 Reservoir is "plastic tub" from Lowes 30 Gal $15 PVC and nozzles from Ace Rating: 5
