This is gonna be a fun one for sure.
One of the biggest problems with handwatering as I did last grow was the extreme workload, sure only 5 plants but to haul water every 12-14 hours for 10 weeks (without a missed day ever) in a wheelchair was a bit tough.

There are other problems with this natrually like keeping pH on an even level it jumps around all the time and the biggest problem will be to keep the reservoar temperature low enough for healthy roots.
The Amazon system is very nice but it is made of black plastic which sucks a bit. I should buy some more mylar to cover it in.
I know many growers had problems with that and solved it with mylar or mounted cooling fans in the reservoar (or both).
Still, I can leave my home for a few days this time around.
