Actually, I have changed my mind, the 5 inch would be better as the mars hydro will heat the space quite quickly. My fan is on full and my space never gets above 28'C. I think the mars may be a little hotter running and with the smaller space it may be difficult to control the temps. The 5 inch gives you the option to move more air to keep heat down.

I would suggest as low as possible unless you have major heat issues. With a tent that small, just opening daily should be enough air intake 🌱👍

I leave the door pathway open and temps can reach 29c sometimes more in flower. I have a 200w LED.
Decided to go for the 5inch as its only a quid more

2x2x4 = 60x60x120
In M thats .6x.6x1.2= 0.432m3 volume in your tent, considering your flow is 105m3/h that fan is more than enough to freshen it up.
But as the boys said earlier it depends on your running temps.
You also need to establish efficiency of your exhaust, if you have a CF with an exhaust thats a lower rated m3/h is your tent going to inflate like a balloon? :p

Either one will be fine but the 4 inch will manage jus fine. For that setup you only need to move 25m3/hr. Good luck and happy growing

Depending on how big a light but a 4 inch should do it. Heat build up is what I am referring. If it is like a 100 or 150 watt light a 4 inch should be enough

Cord for Vivosun Controller to automate an electric heaterI have a Vivosun CFM In-line duct with the Temp/Humidity controller. We’d like to connect an electric heater so that it can automatically come on when the temp is low inside the Tent. Any suggestions to what would be compatible to my Vivosun temp/Hum Controller?

Tent set upHo guys, seeing my hold pic, I notice that in my growbox with 2 plant, the left one is always smaller and fatter then the right one, that’s taller, and one week slower. Could something on my set up influence that? Any experience about that?

Bigger Growtent?Do I need a bigger Growtent? At this moment my tent is 40x80x120cm. It’s too small for my 3 ladies, isn’t it?
I thought about a tent 60x60x160 or 80x80x180cm. I think one of those should be ok for flowering my 3 ladies. Having 2x Mars Hydro TS600 now, should be enough for flower
