| Orchid deflaskinf continued in continuation... If the plants in side the flask has reached the optimum growth, then get ready for deflasking. Boil 1000ml of distilled or clean water and cool it. By the time water cools, make ready the community pots , media like firbark or cork etc, the grade needed for seedlings. Some people may break open the flask , But if the mouth of the flask is wide no need for breaking. Add 1/4 strength of any of the fertiliser used for orchids like NPK 20:20:20 Along with a systemic fungicide like Benfil/carboendazime at 1gm./Lit of cooled water. Add 200ml of water to the flask [after opening the cotton plug in the mouth ] and agitate Few times. After a while the agar or gelling medium will dissolve in the water and gets losened. Just hold the flask upside down and jerk the contents out or pull the plantlets with the help of a forceps, into a small tray or dish. Wash in the plants in another 200ml of cooled water and see the plants are free of the gel. Grade the plants according to size and put them in the remaining cooled water with nutrients and fungicide for 10 to 20 minutes.grade them and spread them according to size. If needed slightly trim the roots if they are long. Plant them in community pots with the appropriate media in 10 or 20 plants accrding to size in com pots and keep them in a humid place with 50% shade and frequent misting with the same type of water used for washing the plants off the gel. In temperate zone the plants should not be kept where night temperatures falls below 70*F. |
