Yoghurt containers as mini-greenhouses
Posted on March 19, 2008 by Ian
Willem van Cottem of Desertification has a very interesting post about the use of transparent containers as mini-greenhouses. You can use them to get seedlings started indoors in the Spring, or in arid environments (since it cuts down on water usage prior to transplantation). They are also useful for transporting the seedlings.
I would be a little concerned about hardening the seedlings - that they might not be able to handle the desiccation without significant die-back - but I suspect that he has taken that into account.
MY REPLY (Willem)Thanks for your appreciation and linking on your blog. I fully understand your concern about the hardening of seedlings developed in such “optimal” conditions. My experiments showed that it suffices to take off the covering pot for a short time every now and then. Exposure to the “indoor drought” in my house seems to harden the seedlings significantly and limits the possible development of fungi, e.g. moulds. More experiments in different conditions on different continents are certainly needed to fine-tune this method. It would be nice if people, setting up trials with such mini-greenhouses, send a short report with a couple of pictures to me at <willem.vancotthem@gmail.com>. I could then collect their information and summarize the possible advices for improvement.
