I have a year old Bloom box..this is my second season. It appears my timer for my water isnt working...? I Did my daily check and the rock wool was dry in the flower side. Theres water coming from the tubes when I push manual override but that only lasts 20 minutes...hardly enough to keep my plants watered....so the tubes dont seem to be plugged. But when I switch it back..theres no water. Any suggestions?
