Very Small Greenhouse, lots of questions.
I am going to build a very small greenhouse out of two 4' x 3' window panes, and have a lot of questions. It gets very cold in Nebraska during the winter, and I want to be able to transfer seedlings to it that are started indoors.
I have thought about providing heat using a black 5 gallon bucket with an aquarium heater in it. Do you think this would provide enough heat for the seedlings?
Can this small of a greenhouse be placed directly on the ground, or should it be raised and the bottom insulated?
What is the best direction for a greenhouse to face?
Any info is appreciated. Thanks.
