Some more decisions about the actual grow room.
The room is about 10' x 11', plus there is an attached bathroom which I will use for moms and cloning. I was thinking of starting off small and then scaling up once I have the technique down and the kinks worked out.
To start, there would be three stages, 15 days each, in a linear configuration, using SWC (shallow water culture). Each stage would be comprised of 2 Rubbermaid Roughneck totes (the 16" x 24" ones) placed together lengthwise so basically each "station" is 24"W x 32" D (16" x 2). So i'm thinking 1 x 600W HPS for each station, as i'm going straight from rooted clone to flowering. Between station 1 and station 2, all lower growth would be trimmed, to get a main cola "pop can" grow. This is actually one of the reasons I went with Endless Sky.
I need some sort of shelving to hang the lights nice and low above the SWC tubs... will wodden shelving be safe? If not, where do I get metal shelving that can be slapped together in custom configurations?
Also, how do I calculate how many air stones I need for the tubs?
