LMAO Griswald Christmas !!!

I use a palm full which is about 3 tablespoons in a 48 gallon reservoir. I would start with 1 tablespoon in an 18 gallon.

Hydroton won’t constrict it the stem will actually move the hydroton as it gets larger. I don’t even use a lid on my 5 gallon buckets and they sit in sunlight for 14 hours a day in the summer. When it rains they get fresh water. I usually keep reservoir 3/4 full when I know it’s going to rain.

pump timing the plants will let you know if you need less or more time. As long as the plants look good keep the timing unless you want to adjust a little at a time either reducing watering by 30 second - 1 minute intervals. You could also play with the time the pump goes on from every 15 minutes try every 18 - 20 minutes see if plants look good after 24 hrs. Again these are things you will eventually dial in for your area and the time of the year.
