Growing fresh in containers is a great way to ‘develop’ your garden, and allows you to grow fresh vegetables and herbs, regardless of how much land you have access to, if indeed any.
A windowsill can suffice for certain carefully chosen greens, but pots and containers are also useful to keep ‘control’ of the growth even when you are lucky enough to have space in a garden.
Everything you want to grow in your greenhouse depends, in most cases, on where you are living (of course) and the growing season you are currently in.
This is important, as is the temperature the greenhouse normally reaches. Most amateur gardeners choose a place that is easy to access, and easy to maintain.
Of course if you wish to invest a bit more in the form of installing heating system and light systems, you can increase practically anything all year round.
