I made my own cloning machine out of a 5 gallon bucket. I used pvc pipe and have 4 misters coming off the pvc pipe which is connected to a submersable pump. It sprays a fine mist up to the top of the bucket. My question is how long do I mist for? My hydro dealer told me 1 minute on 4 minutes off. Where do i find such a timer? He told me his timer is $80 I feel that is way too much.Please help!!!
