  Plastic Bottle Greenhouse – Recycle and use plastic bottles as a greenhouse for seeds starting indoors. See how to start seeds with these simple steps and save money on seed starting containers or trays. 

Billions of Plastic Bottle containers are use and thrown in to trash every day, why not do you part of saving the environment by recycling (reusing) some of them to start seeds, You can use plastic bottles to make a miniature greenhouse or mini greenhouse that you can use to start seeds. Start your seeds indoors a few weeks before the start of the grow season to get a jump start on your vegetable garden and extend your growing season.

This is great especially if you live in an area like New England with a short growing season. This is a great container to start plants like peppers, tomatoes, cucumber, corn, basil, oregano, chives, sage, dill, thyme, cilantro and many more.

Cut the bottle in half or cut it 2/3 bottom and 1/3 top, Using a drill or a hot nail gun, make a few holes towards the bottom or at the bottom of the container 

Plant Seeds

fill the bottom part with your seed starter mix (how to make an inexpensive seed starter mix) Depending on the seeds and how many seeds or containers you have, Plant between 1 to 4 seeds. I usually do 2, so that the seeds have room to grow. water the mix inside the container.

After Planting           

Put the container in a warm area, once the seeds germinate move them to where there is sunlight like a window in a warm room or under a grow light

Seedling care    

If you put holes towards the bottom of the container, that area below the hole will act as a water reservoir so you don’t have to water that often but if you have holes at the bottom you have to check it regularly so it does not dry up.

Remove the lid

 When the seedlings grow up to the level of the lid, you can take out the lid and let it continue to grow in there. When the seedlings are fully grown, you can move them to a bigger container or transplant it to your garden after the last sign of frost in your area.
