You don't need a wet vac, just you a cheapo water pump and 1/2" line to a drain. There will still be _some_ water left in the system below the fittings, but its not a critical amount.
herbie the love bud Reviewed by herbie the love bud on . Changing out my nutes with farm and controller setup Okay... I had stopped using my controller but am debating whether to sell it or not. Mainly cuz I haven't a clue as to how to properly drain my system without making a complete mess. Now do I have to drain the farms into the controller meaning if I empty the controller, will the nutes from the farms drain back into the controller so all I would have to do is empty the controller? If so, I guess I need to have the tubing running from the farms to the controller pretty much at ground level Rating: 5
