Wow. We got rain. Guess we are lucky this time. You have my sympathy. Just to let you know, we are loving the shelving units we got like yours.
We used the heat mats on a couple of the colder nights and zipped up the plastic. While it was freezing out side or nearly so, the little greenhouse was warm as toast so to speak.
Your pictures of your units inspired me to buy them.
Our little green houses are five years old.
Yes, we use heating pads and grow lights below and above our plants.
The peppers, cukes and tomatoes are doing very well.
Unfortunately, only 2 of 10 jalapeño seeds came up (bought from Pepper Joe’s in Iowa.)
We were at Lowe’s for bags of bark and planting soil yesterday. I bought two jalapeños from their stock for $5.
