I’ve considered getting a hydroponics setup so I could have decent tomatoes in Winter, but thoughts of this sort of nonsense have helped keep me from acting on it.
Ping list ping? And see my previous.
I grow tomatoes in the winter, but I don’t have a hydroponics set up. I just use a soiless potting mix, a south western (mostly western) patio door and a T5 full spectrum grow light that I ordered from a seed company.
During the short winter days, I turn on the grow light at dusk, and leave it on to simulate the length of summer days.
