Yoghurt pots as mini-greenhouses (Willem)

Yoghurt pots as mini-greenhouses
A major part of my life has been dedicated to the combat of desertification and alleviation of poverty, in particular that of rural people in the drylands. One of my main objectives is to find cost-effective ways of helping these people to get better standards of life and to offer them opportunities to apply the best practices in that combat of desertification. Success stories have been registered in this combat all over the world. Unfortunately, these best practices are not yet applied at the largest scale. Although some very efficient and cost-effective technologies and methods have been developed and repeatedly described and recommended to decision-makers, their application rate is still dramatically poor.One wonders why it is seemingly more easy to spend billlions at enormous programs and projects than to provide reasonable financial means for large-scale application of the best practices. It sounds a bit discouraging, but it is not. The day will come that people will be aware of the necessity to turn to simple, but effective methods, instead of spending too much at non-productive initiatives. That is why my personal interest is focused on simplicity and cost-effectiveness, e.g. recycling waste or saving valuable seeds from the garbage bin (see our project “Seeds for Life” at http://zadenvoorleven.wordpress.com).
Continuously looking for new opportunities for container gardening, a wonderful method for producing food in the drylands, I recently did some experiments with transparent yoghurt pots. I thereby found an easy way to transform these pots into mini-greenhouses for a windowsill or a table close to the window.
Below you will find some pictures explaining the functioning of my new (?) mini-greenhouses, in which small quantities of seedlings can be grown before being transplanted. Maybe someone did the same before, but up to now I didn’t find traces of this method. Should you have more information, don’t hesitate to send it to me.

Advantages of this method
could be :* Possibility to grow seedlings indoors (even before Spring in temperate regions, like in Belgium).
* Possibility to grow seedlings with a minimal quantity of water (avoiding drought outdoors) inside the house in the drylands (not in the garden outside) .
* Easy way to check germination daily.
* Easy way to regulate moisture level in the “mini-greenhouse” (lifting the transparent yoghurt pot, covering the seed(lings), to aerate whenever needed).
* Opportunity to choose the right moment (dimension of seedlings) for transplantation.
* Opportunity to reuse the same mini-greenhouse multiple times (easy to clean after transplantation).This is probably a method which could tremendously help rural people in the drylands. It suffices to offer them free heaps of “yoghurt pots” (which should not be littered anymore by people in the developed world, but washed and cleaned!) to have them growing seedlings of certain crops in an optimal way, without having to irrigate their garden daily with a huge quantity of water (isn’t saving water in the drylands a MUST ?).
I wonder if we could not set up local or regional collecting points for these yoghurt pots and offer them afterwards to NGOs for their development projects in the drylands. Impossible ? Anyway, it’ would be much easier than constructing a dam or boring well No. 126.417 ! Why ? Well, here are my pictures. Enjoy !

  1. What a great idea.
    I myself have used plastic bottles before as mini greenhouses.
    I will have to keep an eye out for these clear yoghurt containers and give this a try.
    I can see that because they have a flat top they sit very well on the ground when turned upside down
    What a great idea to raise young seedlings and strike cuttings!
