One of the advantages of growing plants inside a greenhouse vs an open land is that in a greenhouse, you can control the environment where the plants grow. Basically, you can plant anything that your heart desires, even produce that are considered seasonal, so long as you give them the environment that they need to thrive in.
That said, don’t be so drastic trying to grow winter plants in the summer, and vice versa. You’d want to rotate your crops just in time for the weather they’re best suited in. Still, you’ll need to put in the extra work for most of the time. For instance, you’d need to ensure that temperature and humidity are optimized. You’d also want to make sure your plants are getting all the water and light they need. It’s a lot easier if you have tools like the Mars Hydro TS 3000 which can provide all your plants’ lighting needs especially during those times when the nights are longer.
