My pal is helping me setup a Iws system and has set the brain for the feed to come on once a day for a hour I've never done Iws before but have read that you can set them over 3 to 4 times a day for shorter periods now I'm thinking it might be better that way because it's putting fresh feed and air through them instead of leaving them in the feed for an hour.. he disagrees saying by the time the water runs out of pots it will be filling them back where it's best to let them dry a bit! A few opinions would be helpful
