So I guess I'm asking for opinions on building a hoophouse. if I built one large enough, could I theoretically put my potted plants in there as well as my cuttings and baby plants and would they survive the winter? Typical weather here in the winter is 60's and low 70's but it gets down into the 40's and 30's at night....then of course we get the week long freeze spells we had last winter. I think I can build a hoop house for under $200 and just wanted to make sure it's a good investment. I'm also interested to see if it's a good idea anyway because I start vegetables from seed every spring too and I hate waiting until mid March to take the plants outside.

The reason I suggest it be portable is because one year under the Florida Sun and your plastic will be yellowed, brittle and worthless. So some kind of structure that you can make based on your budget where you can take it down once things start warming up will save you a lot of expense of having to replace plastic every year. It's also far too hot in the summer, and anything inside would cook!

A more permanent solution would be a greenhouse, but you'd need heavy shade cloth during summer and high ventilation. I have mine under deciduous trees, that way during winter there's plenty of light, and in summer it's shaded, which helps but I still need to use shade cloth to make even staying in there bearable, so it's really not use-able in summer.

So there you have it - whether it's hoophouse or greenhouse will really be determined by your budget, but you'll get the results you want with either.
