Wick system is one of the easiest ways for plant novices and pros alike to keep their plants water needs managed. Insert your wick through the bottom of the net cup, with the inside length of the wick at least half way up the height of the cup, before adding your growing medium and seed or starter plant, and the remainder of the wick should hang from the bottom of the net cup into the water reservoir.
The wick will then suck the water and nutrients up from the reservoir and feed your plants as they need.
