This is a green house made out of a plastic bottle that keeps your plants really warm inside your house and traps the heat inside from the sun coming through your window. It can be made in less then five minutes. Hope this works as good for you as it did for me.
Step 1: How a Greenhouse Works
First of all what is a greenhouse? A greenhouse is a glass building where plants grow that need protection from cold weather. And how do these structures help plants grow? Simply greenhouses let sunlight pass through the walls to heat up the air inside through radiation (not cancerous radiation). Once the air inside is hot it does not cool down very fast and if there is still sunlight it will stay warm because of the glass protecting the inside from the outside elements.
Step 2: Materials You Need
To Make this plant growing machine you will need a bottle a size big enough to grow the plant you are going to, scissors, tape, soil and seeds.
Step 3: Cutting the Bottle
The first thing you need to do is cut the bottle in half. It maybe hard to cut through the opening so if it is just cut that opening off.
Step 4: Wash It
Wash the bottle thoroughly so that there is no residue.
Step 5: Getting Dirty
Fill the bottom half of the bottle with good planting soil, you can put some added nutrients in it if you would like.
Step 6: Making Things Grow
Get some kind of seed that would fit in your greenhouse and put it in the dirt.
Step 7: Giving It Moisture
Before you close and seal your greenhouse up put a bit of water on the inside.
Step 8: Sealing the Deal
After your seeds have been watered you are ready to finish your greenhouse. Start by taping the top to the bottom and make sure it is airtight. After you have sealed the to[p to the bottom put the lid on and you are done!
Step 9: Making Things Grow Taller
When everything is sealed put your mini greenhouse in a windowsill or somewhere else that has lots of sun. You will notice after a few days that the inside will get very moist don't worry this is a good thing it gives your plants water. What causes this is the air inside the greenhouse being warm, but the air outside is cooler this causes the moisture to condense. This can also be seen in your vehicle when you have the heat on inside and the air outside is cool though and it causes your windows to fog up.
