Thanks man. Hydrotron is the most easy to clean but perilite is very good. You can drip to waste or to rez and recirculate. Use it in grow bags.

You can split the pellets and was off all soil then put in hydrotron or perilite and be totally soilless. Or leave them on works for me but i got used to 1 inch rockwool cube and hydrotron.
The thing about drip to a rez is you can leave it 24/7 with no problems.
