Don't forget to flush the pump spray pretty good. Just fill a glass with clean water and stick the tube in the glass and just spray til that glass is empty lol. That's what'd I'd do just to be safe.
yea thats what i done rinsed it alot with plain water then put a dab of liquad soap in there with some water then shoot it up pumped the soapy hot water through it then rinsed a bunch then pumped plain water through it a bunch to make sure all the soap was out my lights are about to go off in about 15 min so ima spray'em right before the lights go off if there fine in the morning ima spray again just my fan leaves because im in flowering right now but i dun got any buds so im not worried about mold
