Here are few pictures to give you a look inside a Hydroponic Greenhouse
This is the nursery where it all begins. Seeds are planted in rockwool cubes and after approximately two weeks are transplanted into the grow channels.
This shows a crop of lettuce and other greens nearly two 2 weeks after being tranplanted.
This is going to make someone’s salad awful tasty.
This shows a example of a green house at nearly full production. Crops are planted just about once a week in zones of the greenhouse. In this manner you always have tasty, fresh lettuce available.
Another broader view of a greenhouse at full production. Space is managed to allow for maximum production.
