I'm looking for something that will handle good sized plants 90-115 days old at the end of the growth cycle. The plants will be scrogged and that is why they'll be seeing 30+ days of veg. I currently run an aeroponic setup, but it's a bit noisy for my apartment. You can hear the vibrations from the pump through the walls, even with a towel under it. I don't mind spending up to $500 on a system. It will only be for 12 plants.
