This design is part of my Plant Grow Tent Project:

I designed this cap to simplify my entry into the world of cloning. This is a work in progress.

• The idea is that the cap offers good but soft fixation of the plant shoot.
• The second function is to cover the water completely to reduce evaporation.
• Lastly, it enables one to lift the plant to refill the water once in a while.
• This design is not meant for large-scale cloning, just for two or three plants, for fun, and trying out new things with your kids.
• Of course, you do not need to use water; you can use your favorite grow medium.

• Maybe you could help me out by posting a comment about what works best for you.

• If you need caps with different diameters, just let me know, and I will add them.

• The bigger the plant, the better.
• The bigger the bottle, the better.
• The smaller the neck of the bottle, the better.
• Use bottles that are dark to reduce the amount of light exposure to the roots.
• Install the sponge in a way that you can easily add water with a lab wash bottle (plastic laboratory squeeze bottle).
• The benefit of this design is reduced vaporization, and with reduced air exchange, the water stays good for longer.
• Distilled water or rainwater makes no difference.
• Do not damage the skin of the plant except where you need to break it loose or cut it off the mother plant.
• If the plant is not healthy, too small, or not a complete shoot, then nothing may happen.

Happy Cloning!
