I just installed some last night. A friend has been using them for a few weeks with great results and loves them.
They also enabled me to make my “old man watering system” way easier on my back.
I zip tied a plastic pipe into position at the fill port.
Then ran some tubing to them that I shielded inside another pvc pipe.
And all the tubes come up to the front corner of the tent. I just shove a funnel into the end and fill each tube.
No more bending and reaching and crawling into the back of the tent.
I go out of town frequently for extended periods so I am running mine in conjunction with blumats. I’ll keep updated about how this setup works out.
