Sorry to change the topic, but you use hydro halos correct? Opinions?
Yes I do! I love them. Except they are awfully expensive for what they are. Ah the price of convenience. They fit perfectly in the 1.5 gallon "airpot" knockoffs I have. I don't use them with a pump, I just run the 1/2" hose to an easy to reach spot and handwater. A funnel is extremely helpful. Makes watering in the back of the tent much easier on me. I can't reach and bend way in there any more.
I know some people have had trouble with them but a little pregrow prep work helps. I rinse them in the sink with a short piece of hose to make certain all the holes are open. Some need a trim with an exacto knife. Getting them set "flat" in the pot can be a task. If you aren't watering enough volume and they are tilted, the water just runs out one side. Not really an issue just something to be aware of.
At the end of a grow I rinse and soak them in some vinegar to break down any residual nutrient salts. They definitely get a bit crusty. Short hose back on in the sink and blast them with the sprayer, check all the holes are still open and functional.
