How big of a commercial greenhouse do I need?

We always give the tip to buy one size larger than you planned. Remember that your plants will grow. That compact space you used to start the seeds will triple when plants are potted up. So be smart and think about the plants you want to plant before purchasing. However, we do understand that you might be a little hesitant to purchase a bigger unit intially, so you will find that some of our products are extendable, so you can also start with a small size and upgrade later on.
