Auto Top-U grow tanks are the ideal hydroponic system to use when you’re away on vacation or when you have a busy work schedule. This non-electric hydroponic system waters your plants passively - which means it relies on gravity.
We carry both Auto Top-Up hydroponic systems - one with a tank and one without. For beginners, we recommend the use of Auto Top-Up’s Grotanky because it’s an all-in-one system. However, if you’re looking for just the components without a tank - you can find it here too.
