Wow, thanks! I guess I really don't see many people grow with this type of system either. I guess that is why I can never find out the proper info. It has been a really easy system to operate and I am almost at full capacity.
I think I will keep the rockwool slabs but I have decided to put the trays at more of an angle so that all the water flows out of the trays and back into the res. I bet this will make my slabs dry, faster. So I will most likely have to adjust my watering times again, but at least the slabs won't sit in a little bit of water.
It is turning fall in there and I am trimming off some yellow leaves. They will be harvested on monday and all the heads are milky white with some turning to amber. The hps lights are not good for accurate color, so I will take some pictures right before the lights come on and at harvest.

Thanks again!

Also, I have read that it is good to flush the Rating: 5
