Hi! Just make sure the coco stays moist but never too wet! It's fine to do a few seconds every few hours, and adjust based on how much the plant drinks. Do about 5-10 seconds every 5-6 hours; if it's too little, keep it at 5-10 seconds every 3-4 hours :) if it's too much, do 5-6 seconds every 10-12 hours :) then adjust the timer based on the plant :)
