These two wire shelves would fit an IKEA Milsbo(tall) Cabinet that is being converted into a greenhouse cabinet for plants. It can easily take the same weight as the original glass shelves. It is also easier and safer to handle than glass. All you need to do is to place them in the same brackets that are holding up the glass shelves in your Milsbo Cabinet. Together with a suitable fan, it will provide good air circulation which will promote transpiration and prevent fungal growth. It will also help to even out the humidity and temperature through out the cabinet. Lighting for a lower shelf can easily be attached to the underside of each shelf using cable ties. These shelves will make your plants very happy.
