If it is week 1 of veg then a small fan on low power, just enough to move the leaves a little bit. Later on - both bad boys on. Big fan on the top, small one on the bottom. Good luck!

Speed of outgoing TD Silent
Do you adjust the ventilator speed over time? I have a TD Silent with 5 possible speeds and keep the lowest speed at night (so I can sleep) and on 3 or 4 during day to be sure. Is there a trick to find the best yet lowest speed?

High humidity
Hello. Even with a dehumidifier and a 24-hour extractor, the humidity is still above 70% and one of the plants is almost in the flowering period. Can I add expanded clay on top of the vase to see if it lowers the humidity or putting more perlite will solve this? Thanks.

Growtent Humidity control
How do you control humidity/temp when using a grow tent? is it enough to put a dehumidifier in the same room as the tent and close the tent and just blow the air outside with a fan and tubing? Do u need an intake fan too? Or does the "good air" gets sucked in enough without ? THX

How can I reduce the heat in my 5x5 tent (650w light bar/6" ac Infinity and a ton of fans) without AC? Do I have to leave tent open?
5x5 tent is in a kind of lung room (utility room) that stays around 20C/68F. The tent always seems to be at 30C86F with lights on. Ive added and moved fans, opened more intake vents. I have AC, but its -25C/-13F outside. Id like to drop the daytime temp 5ish degrees for flower.

High humidity temporarily
For a few hours yesterday the humidity in my grow space went up to 90%! Should i be on the lookout for any issues? The fan in the tent came loose from the pipe. Thankfully nothing was damaged. Fixed it afterwards.

Utilizar filtro de carbono sin manga??
Can I use my carbon filter without the sleeve it comes with?? It's just that when I put it on, I lose power in the extractor and the negative pressure isn't generated since the duct from the extractor is bent??

Are (constantly) high daytime temperatures a huge problem in flower?
My day temperature since turing my light up to max during flower are reaching 29-30c | 84.2 - 86f, while the daytime RH is at roughly 40% - 50%. Is the high temperature something to be concerned about? pics 1 and 2 are the exact same data as pics 3 and 4, just set to c/f each.

Cardboard box method for dehumidifier
Hi 👋 can anyone tell me what success they’ve had using the cardboard box method for housing their dehumidifier? My unit is heating up inside the tent so much as it works harder during flower to keep humidity levels lower. Before I make the switch I wanted some opinions?
