I dont know how many plants your feeding or the size of your containers but i think this would need a shit ton of ice cubes every time you water. I have 5 plants in 3 gallon bags on the go, water every 3-4 days and use around 4 gallons of water each time. I know the idea, i watch my aunt and uncles place when they travel and the order was...the orchid only gets one ice cube a week. i thought it was weird but that sucker is thriving..
