Changing out my nutes with farm and controller setup

[hatecable]

if its a plastic based fabric i would go with melting a hole in it. I dont mean just stick a lighter up there and let her rip, but find something metal that is reasonably the size you want, heating it on a stove and the letting it melt its way through. That way you wont have any unraveling of the material. Otherwise you may can find a large hole brass gromet kit that you use to repair tarps. That might run you 8 bucks or so, but it would be a professional looking hole.

That was excellent advice from hatecable. But you should actually sit your WF up on something at least an 1" or 2".

instead of modifying my tent?

No i think he means to just raise the farms up to help it drain them completely. It would be hard to get the hoses to lay perfectly flat for the entire line to the controller so you'd raise the farm up slightly above the inlet of the controller to ensure a good flow and complete emptying. You dont want sediment from the hydroton and heavy particles to stay in your nut solution for the entire grow.

Exactly. And if you raise it higher than the inlet to the tent then you don't need to modify the tent.
