Use Plastic Bottles To Make Mini Greenhouses
If you can’t find the materials to build yourself a luxury greenhouse just lying around, try starting with some plastic bottles. Simply cut the bottom off of the bottles and place some soil inside the base. Then, add seeds or plant cuttings, water, and place the rest of the bottle on top to close it.
The result will be mini-greenhouses that allow the plants to maintain humidity and comfortability. Place the bottles underneath a window or in any sunny space and watch them grow. Your new plants will become big and strong enough to be moved outside in no time!
