Yes, we are going to have 6 months of snow this year, but we can have microgreens!
I have one of those big Amazon grow houses in the garage, about 4x4 on the bottom and about 8 feet high. I have a small ceramic heater in it. I can roll in a 2x4 x7 feet high chrome shelf and on it I put 3 big Walmart flat storage bins.
I have just filled them up with clay beads from ammie, and I have the latest COB grow lights that don't need a fan. My bro-in-law took my old lights and totally cleaned them out, and he loves them.
The bottom tray is a sump with the pumps. I make up an approved hydroponic solution and let it all run. Takes about 2 weeks to harvest.
Right now, one of my trays has sprung a leak. pooey.
ps. I repaired the leak and it just drips now. I hope it clogs up. I now need a new high-lift pump for the upper tray. Most of the cheap fountain pumps only lift 1-2 feet.
pps. got a 6 foot lift pump quite cheap. Everything still drips but it's being caught by the sump. Growing radishes as the test.
