Easy To Use: No tedious installation, just drill some holes at bottom of a bottle or cut it, then a regulating valve that can adjust the speed of the flow.
Precise Control: Accurate flow control to keep your plants from drying out, give different amounts of water for different plants and flowers, not like others that water too little or too much. For some plants, old leaves just turn yellow and drop. But if new growth is yellow it could be a sign of overwatering or underwatering.
Fit On Most Bottle: Fit most below brands bottle: Dr. Pepper, Pepsi, coca cola, Lipton, Deet Coke, Aqufina, or other bottles that have 1.1inch inner diameter capsules, which are easy to find.
