Taking care of the different systems is really quite easy.

Every harvest you need to clean and change all the reservoirs.

Each system has a garden hose fitting and valve. Attach a garden hose and run the hose into the bathtub.

Open the valve, plug the pump in and drain the reservoir. Double check your hose so you’re not spraying water all over the bathroom!

Listen for a sucking sound from the pump. That tells you it time to unplug the pump.

Don't forget to close the valve at this time! I heard about a guy that sprayed water all over himself like a total idiot because he forgot to close the valve. I don't want to mention any names but it starts with stink and ends with bud.

Get a garden hose adapter for your sink and attach your hose. No need to haul water around unless you like that sort of thing.

Don't get stoned while you are filling your reservoir! Don't ask me how I know this...

After harvest remove all the plant matter and clean everything with bleach water. Run a little bleach in the water for a couple of hours and then flush with plain water a couple of times.

Really clean the shit out of all your stuff every harvest. You want your grow rooms as clean as a hospital. Actually cleaner would be better.

Always have a complete set of clean sprayers. Replace the sprayers every harvest and put the dirty ones in a cup of soapy water. Then later scrub the sprayers with your wife's toothbrush (just kidding).

That way you always have a clean set of sprayers ready to go.
