Q&A for How to Make a Mini Greenhouse

Greenhouses retain more heat in cooler climates, and allow for a more controlled environment.

Yes, but it actually depends on how tall your plants and toothpicks are. If you're using sticks and you have a tall plant, you might want to go with taller sticks.

You need to make sure it has a way that you can ventilate it on a hotter day, such as a doorway or window into the greenhouse that will allow outside air and wind in.

Clear plastic sheeting works. If you have an actual building, glass is optimal.

Any color works, you just need the cover to keep in warmth and moisture.

You can if you want, but it will ruin the effect of keeping in warmth and moisture if you add too many holes.

You can use plastic bottles, sticks, saran wrap, and really anything that can hold moisture. Cardboard would also come in handy.

It's a good idea to have some way to ventilate your greenhouse when temperatures rise so that the plants inside do not get too hot. In summary, yes, but make sure you have some kind of way to ventilate it, such as a door, window or some kind of flap that opens.
