It must be catching. Hubby is just finishing up my next sq ft gardens. One is 4x4 and the other is 2x4. I will use 15 squares to plant heirloom seeds that I ran out of room to try this year.
I plan to start 3 cherry tomatoes towards the end of summer to bring inside and put under the grow light, along with some herbs. I just can not stand supermarket tomatoes in the winter, and I do so long for vine ripe tomatoe all winter.
Eat cardboard...same flavor, and you'll save money.
