Creative mini greenhouses can be made using a variety of common household recyclable materials. This is a guide about mini greenhouses using recycled materials.
I use large, clear, round plastic water jugs from the grocery store as greenhouses. I cut them with a coping saw and leave a small attached area. I put the seeds inside in proper soil and close the top. I leave the lid on the bottle in early spring. I put these in a sunny area during the day and at night they come inside.
Once they can be left outside, I remove the little lid on the top half and they continue to protect the new seedlings. You need to avoid the center of the bottle and you need at least 4 inches of soil so that the plants can survive until they are transplanted. Good for the environment because you can reuse these year after year.

I set out plants I grow from seed and they need protection from wind and pests. I use clear juice jugs with the bottom cut out and no lid as a mini greenhouse for each plant. The plants get off to a great start! This also works to start seeds in the garden.

I'm thinking of trying to make a small indoor greenhouse for next winter. I have an odd-ball idea for one and would like to get some feedback on what people think. I want to take a large plastic storage bin (the bottom part is clear) and turn it upside down, put the seedlings on the inverted top, hook up a plant light in it and put it in a sunny window. The bottom part of the bin would be snapped back in place to keep the humidity in there. Would that work? Does anybody have any thoughts on this?

I also think you are trying to do too much with the storage bin. The lights and other instructions will be a great thing and should get you through. Good luck
Save the little plastic containers with attached lids that some fruits come in and you sometimes get for take out food and use them to start your garden plants. They work like mini greenhouses.
Safeway has muffins in plastic containers that have a space for each muffin. They work well for mini greenhouses, too.
I cut the ends of the two litre clear plastic pop bottles and put them over my small transplants in the garden. Make sure to remove the cap as this allows the circulation of air to the plant.
Tomatoes love these!
