Lettuce and basil right now. I'll put pepper plant in there soon, I have some sprouting now.
I have a new grow lights to hang up that should be here today. So far I've built it with on-hand materials other than some PVC fittings and clay balls.
I'll expand if it works well. The room will be getting remodeled this summer. I have larger tanks to replace both of those tanks.
Humidity stays around 45-50%RH all year round. My house is real dry in the winter. I have a humidifier on the furnace (which I'm pretty sure is useless) and a big ass one on the second floor. Both tanks will loose a gallon a day in total in the winter. Will likely be more with this setup. I have an auto top-off system.
