What are your thoughts on supporting the inn tainer. I plan on not cutting it down. So the options are the plastic pipe drilled through the outer to support the inner. Or plastic pipe placed vertically in the res to support the inner.
Another question. Using 27 gallon totes I was going to use two 5” net pots for wicks. Is there a fear of over water ? With not cutting down the inner I assume I’ll get 23-25 gallons of soil in.
thanks.
Fear of underwatering for me in my Costco 27 gallon totes, mine are drying up on the top but I only put 3” holes for the two 5” net pots. Btw, this is how you move them on a dolly with shopping cart wheels 5 1/4” to get over little bumps.

So I got some of the smaller totes,45L.Thoughts about using the lids to cover the soil rather then mulch?Ill cut them in half and put a notch for the stem.
Thanks.

So do you guys just keep topping up the res or let it go down a gallon or two then top up?
My auto-water setup is set to come on an hour after the lights come on and then go off an hour before dark. It drips as much as it needs and then each individual SIP valve shuts off when full. I end up going through 3-4 gallons per day with 4 SIPs + a dozen or so smart pots on a 2 minute spray timer.

Since I can see my res level through the view port I fill when necessary, in early veg I might top off once a week then later veg every couple of days, during flower now they are really drinking allot of water , now I am topping up daily because they drink about half the res each day
