I would encourage you to use gravel on the floor so you can dampen the gravel to create a humid environment in the greenhouse.

You should try and utilise the space in your Aluminium greenhouse by growing tall plants like tomatoes.

As you would expect the atmosphere in greenhouses is very warm and moist and therefore requires lots of ventilation. Most greenhouses have windows in the roof to allow hot air to escape.

Greenhouses are a great investment because they let you grow seedlings when it is too cold outside.

You can buy cheap Aluminum greenhouses here. Check out the bargains!
