Now there are certain things you're not expected to or would have a hard time growing in a hydroponic setup.
Plants that take up a lot of space to grow are inefficient to grow in this sort of greenhouse. Watermelon and other melons, squash and corn are just some of these vegetables. They're all taking a massive amount of space to expand.
Some varieties of pumpkin are bred to grow enormously. Give pumpkins all the space they need by planting them outside where they can spread and increase the size of anything they want. You don't want to end up with the pumpkin that ate your hydroponic greenhouse, after all?
Many plants require bees to pollinate them, so they have both male and female flowers. These plants are a little labor-intensive to grow hydroponically, since you don't have any bees within the structure. However if you are willing to learn the painstaking task of pollinating these plants on your own, some of them will still do well in this environment.
Flowers have varying growing conditions, so you can't grow any of them with success. You're going to need to study every kind of guy to see if they're going to work for you. Until you know what varieties you want to grow, stay away from the flowers for this form of setup.
Of course, you can try to develop whatever you want, as long as you know that not all things can turn out as ideally as you want. But if you're new to hydroponic gardening, set yourself up for success and start with vegetables and plants that have performed well for others. And when you learn more you should experiment. This way, you'll get some good results for the first time you're going around.
