These are economical, open-sided, small plastic baskets/pots - great for growing many types of Orchid seedlings, miniatures, and other plants. Especially useful for those who are heavy-handed at watering (nearly impossible to overwater).For us, these work well for growing plants in sphagnum moss: Smaller Masdevallias, seedlings, etc. and also for plants that mike lots of air to the roots.Note: These can be combine/nested into our 2 1/2" Standard Round Plastic Pots. The pot in a pot effect allows for ease of checking the growing root system with a simple lift of the inner net basket which minimizes disturbance!
