need help with controlling/regulating temperature of containers
I was told to avoid temperature extreme temperature fluctuations with container gardening, you should place the container that you have stuff growing in, into another container.
I'm going to mention that I have a short growing season and spring where I live is much cooler compared to spring in warmer climates (such as Southern climates).
Even in the summer, although it's hot in the summer, it's still milder compared to summers in the south/warm climates.
If the purpose of doing this is to prevent overheating with containers, and cools down temperatures, then when it's cool out (spring and fall) is only necessary to do this in hot weather? The reason I ask is because it's still low at night with temperatures where I'm at (mid 20's to low to mid 30's). However do containers actually bump up the temperature and act as an 'incubator' for plants?
Why do you do this? Does it help cool the container down and prevent overheating?
If so, how?
I also have some other questions about it and here they are:
1.If for cool weather veggies, you use a light colored container, is this even necessary? In my case it would be white.
2. When would you do this, would it be for the whole season, or only necessary when it's really hot (summer)?
3. I've been told with container gardening you have to water more frequently. By placing the container into another container, does this help the soil retain moisture longer, and as a result, you don't have to water as frequently?
4. I'm going to be placing a smaller container into a larger container. Does it matter that the container I'm growing stuff in (which will be the smaller container, not the larger one) isn't the same size as the container it's being placed into.
