What kinds / make of fan?

The good news about an oversized fan is when you dial it down it will make considerably less noise.

Fan controllers can be had for $20 - $30. Search any online grow store for examples. You can probably get them at a local electronic supply shop.

What are the temps and humidity levels? How close is your light to the plants?
bigsby Reviewed by bigsby on . Can I vent this? Hey so this is my first grow and i wanted to buy this Grow Tent and 400w HPS kit but i'm not quite sure how to set up the ventilation. is it ok if i just set up small cfm fans without ducting? i don't want heat to be an issue, but at the same time i want to keep it as cheap and simple as possible since the tent and light were pricey enough :) any help or tips appreciated! cheers Rating: 5
