● BumbleBailey :
I would actually cover the part where the hydroton was because it tended to grow algae etc
● BumbleBailey :
Yes, one side of the lid was cut so I could flip it up
● TheiZ :
Clay's great at retaining water.
● TheiZ :
Bad for unwanted growth.
● TheiZ :
Did you ever have gnat issues?
● TheiZ :
I took the side vents off and too much light attracted the pests. So I've used mesh netting over my intake flexi ducts.
● TheiZ :
I'm just doing passive with an extractor.
● BumbleBailey :
My tents were in a room, and there was another room before that. I'd always put on gloves and a lab coat at least
● BumbleBailey :
If I was outside I'd strip to my underwear first. Nothing was getting in!
● BumbleBailey :
Honestly it was still less work than getting rid of one infestation
● TheiZ :
3 passives are still too weak for that fan on its lowest setting but the plants don't care. There's enough co2
● BumbleBailey :
You can also baffle the air flow to slow it down
● TheiZ :
It's a 100mm centrifugal that pulls 285m³/h.
● TheiZ :
The filter slows it down a bit, the walls suck in a bit too.
● TheiZ :
The co2 comes straight from the gaps under the door that leads outside.
● TheiZ :
That's at max fan speed of 2500rpm.
● TheiZ :
For a 4x4 tent, you want 100cfm
● BumbleBailey :
I thought that should be about right. Voids the air twice a minute?
● BumbleBailey :
I've been out of this too long I need to brush up haha
● TheiZ :
It's hard to get a balanced positive and negative pressure in the tent.
● TheiZ :
Unless I use bigger duct pipes.
● TheiZ :
There's more negative pressure in the tent by about 30 percent.
