Substrate Homemade Incubator


Now that the experiment could be said, I can make a post. The
ripicchiettatura occurred just a month ago. They were of various phalaenopsis sowing, planting a bit more for the 'stunted, many substrate on Murashige & Skoog, while ensuring a fair rate of germination (at least with phalaenopsis), not long ago to develop the plan very, perhaps for the lack of active carbon which accumulate toxic exudates for the map, perhaps to a certain salinity of the compound.
While you were not very good as seedlings, so I took the risk to use them to do some experiments with a substrate at home. Lost lost, I thought.
So I based on a recipe that is around on various websites on the theme: NPK Fertilizer 20-20-20


1.5 g 20 g sugar
1 g of activated charcoal ground
1 liter of water demineralized
8 g Agar Agar

How do I use a balanced fertilizer with trace elements for orchids NPK 5-5-5. Since the 5-5-5 diluted to 1 / 4 compared to the 20-20-20 it took me 4 times as much, then about 6 grams, a little less.
For sugar I used the normal cooking.
The coal is pulverized with aquarium an electric grinder.
Agar is the one to shop for organic produce.
Everything has been weighed with an electronic scale kitchen, and then in a rather approximate. Agar, it took me a while 'not to take the "pudding' a bit softer so that the roots can sink in more easily.
Everything was dissolved in one liter of distilled water, put into sterilized jars and used in a pressure cooker. Transplantation usually sterile hood.
The first days were not the best, in a flask over the leaves of the plants were burned as I do not know whether to blame the bleach or substrate. They are more inclined to believe that it was the bleach even though it had never happened before.
I think this is because the transplant, after a couple of weeks of settling, the plants have begun to grow, the roots are long, sinking into the gelatin, and are developing new leaves. The intense green is beautiful and brilliant. The leaves grow old and, having left a lot of space between one and another, I hope they do a lot and fast.
The simple and spartan compound nutritional home-made, at least as a medium for transplants, seems to work.
