HPAeroponic/Hempy

I think I have narrowed everything down. Basically I am doing the following:

30 or 40 gallon drums
3 50-55 micron misters per each pointing towards the center.
Aquatec pump, accumulator, timer, and solenoid.

The question is what should I do with the water/mist that accumulates over time on the bottom of the drum.

A - Put a silk screen across the bottom and drain.

Or

Maybe do like they do on hempy buckets. Fill the bottom with chunky perlite and let the water raise up an inch before draining. I could flush the system once or twice a week.

If I do the hempy style resevoir will I get root rot? I would think it would help if the plants needed a little extra water.

Thanks,

Good question; the purists will say use a silk screen, but if I were you I'd do that on half and then use the perlite on half and see for yourself - sounds like a good experiment
