Growth and substrate, I have chosen rockwool and vermiculite as the media. this is 20 days growth, using a flood and gravity drain system. 3 times a day for 15 min. I use Leca (expanded clay for the mature plants)
What lighting works. for the grow room the standard florescent daylight globes work. but fruiting rooms are recommended with 400w tungsten halogen lamps. count the rising costs. I have tried an alternative 14w red halogen down lighters as you can see fruiting is possible.
The materials you need. I took roof brandering to build the framework. Then I used standard painters dropsheet (100 micron). Growers recommend mylar as the reflective backing but I found this too expensive, I have used foiled lined dog food bags. for the flood tray a geyser tray is perfect in the grow room. In the fruiting room I use 33L black storage containers
