done with dirt it seemed like to much of a pain in the butt for our grow room. So we are switching to hydro, dwc to be exact and have a few questions. Here is the first one

I plan on starting 40 seeds directly in rockwool cubes in covered trays with heat mats under them.
Do you think this is enough light i should be able to fit the rockwool cubes into 4 trays



I plan on putting a 150w fluorescent into it?


Thanks guys
