I am on day two of building a pvc green house. I have my plans for the building pretty well set and have a 20 year old roll of plastic (of some sort) my dad had ordered from Sears Catalog eons ago to build a green house with. Mom says he was in a huff back in the day when he ordered it, they kept not sending it and he was in a hurry to get that green house in! It is not your usual plastic, feels stiffer and is more clear than what I see in stores We have a nice old alum table to start seedlings on (8+ feet long) and our green house will be 8.5 x 6. Kind of the max foot print I can fit in the upper yard close to the house. Lots of room under the table for pots and soil in bins. We have old bus tubs to set the pots in for watering.If I have extra plastic, I may have an extra green house in the lower garden some day. (thinking row covers might be a better idea though-pvc raised ones of course) I figure to have room for at least 6 large pots for veggies. Being in SoCal, we don't worry about snow or hard freezes, just the occasional frost. I am hoping to plant a zucchini, a couple of cucumbers and 3 pots of tomatoes. Do have have to hand pollinate any of these plants? We have some gravel for part of the floor, but for now it will be mostly dirt. It is set between a couple of lemon trees, so hopefully not too sunny in there and protected from the wind as well, because it gets hot here, I have plans for "windows" that will lift to allow excess heat out when needed.
