Self Watering bottle greenhouse – Recycle and use plastic bottles as a greenhouse for seeds starting indoors. Starting your seeds indoors before the start of the growing season, gives you a quick start and a longer growing season. 

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

One of the main challenges of starting seeds, especially indoors is watering the seedlings, You don’t want to over water and you don’t want it to dry out. as you know it is a balancing act. so having a free container system where the plants constantly get enough water is an awesome idea and it frees up your time to do something else. 

All you have to do now is to check it ones or twice a week to make sure there is enough water in the container and the self Watering bottle greenhouse system does the rest of the work.

The greenhouse will ensure that the temperature inside the bottle is higher the the temperature in the room or greenhouse.

Cut both bottles in half or cut it 2/3 bottom and 1/3 top, Using a drill or a hot nail gun, make a few holes (3 or 4) at the bottom of the small container. this will help with water intake.

Plant seeds

Fill the small container up to 80 percent with seed starter mix (how to make an inexpensive seed starter mix), water the mix in the container and plant your seeds according to the seed packet label instructions. 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. you can transplant the other seeds latter when they germinate.

Put bottles together

Put some water in the bigger container and put the smaller one with seed starter mix

inside the big one as shown above.

After Planting           

Cover the bottle by putting the other half of the bottle on top and place the self watering greenhouse  in a warm area in the house or greenhouse. once the seeds start germinating move it to a window where there is sunlight like a window in a warm room or  or put it under a grow light.

Seedling care         

with the holes at the bottom of the small container and water in the big bottle, your plant will always have enough water to keep it growing.

All you have to do it to make sure that you check the water reservoir weekly to make sure there is enough water for the next week until you transplant it to a bigger container or garden.

 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.
