Nice canopy, what in the world are those .....beds? that you have your plants in, looks interesting! What's your grow method?
Thanks. it's a 2'x4'x7" tray full of hydroton. I put the clones in 4" rockwool cubes, then buried the cubes in the hydroton. I started with just rockwool but was a little nervous about the roots outgrowing the cubes and seeing light. So the hydroton gives them something to grow into and keeps light off the rockwool and roots. I only flood 3x per day, but the hydroton seems to stay moist at the bottom of the tray. It also has the added benefit of taking up lots of space in the tray so i need much less water to flood it. I'm pretty happy with the setup, but we'll see if i still feel that way after cleaning the hydroton after each cycle.
