Just a note on my Greenhouse. I have 10 flats of tomatoes, peppers, and eggplants grown from seed. At the High School FFA plant sale last week, flats were $15 each. So I have $150 (about $300 retail) of vegetables for the garden. I'm also rooting azalea, rosemary, and Cherokee Roses. ... There are 14 pots of bananas being rehabilitated and I have saved my dying Myers Lemon (too much chicken manure). The Myers had regrown it leaves and has already bloomed.
The cost of building the little greenhouse (less than $100??) has way-more than paid for itself with just the saving of buying vegetable plants for the garden. And there is the learning I had to save the bananas and the lemon.
OK ... pictures:
Current improvements, to extend usability during the spring & fall, that I'll be working on are:
*more air flow & cooling. On sunny spring days of mid 70's, the greenhouse temp is over 100. Not good for the bananas although the tomatoes didn't seem to mind.
* installing a timer & misting system for plant rooting.
