Why Should One Have a Greenhouse to Grow Vegetables?
The main benefit of having a greenhouse is that it keeps a constant temperature and internal environment that is conducive to year-round growing of vegetables, regardless of the weather outside. It’s important to note that those conditions don’t stay that way by themselves but it definitely beats trying to grow everything outside. Once you are able to keep that internal environment constant, build a cheap greenhouse free you can, with a bit of planning, have your marrows grown just in time for the off-season. To give you an example, you could sow some tomato seeds during the month of March and you would be able to re-plant them into bigger pots by around May or so.
