Flasking Medium for Phalaenopsis Seed Sowing & Seedlings
These are a couple of formula's that a number of us have been using for Phalaenopsis. The mother media was designed for sowing seeds with the green pod method, but it will also work with dry harvested seed. Phals generally prefer a medium with weaker nutrients than recommended amount of most commercial flasking media. So the amounts listed below are tailored specifically for Phalaenopsis. Phals are also sensitive to sugar when temperatures are higher, if you find your temps run higher in your lab and you are getting die-off, try reducing the amount of sugar.
Mother Media Formula
13.5g/L P668 (Phytotech Orchid Maintenance Media with Charcoal)
5g/L Sugar
3-5g/L Gelling Agent
1L Distilled Water
5g/L Sugar
3-5g/L Gelling Agent
1L Distilled Water
Replate Media Formula
20g/L P668 (Phytotech Orchid Maintenance Media with Charcoal)
5g/L Sugar
25g/L Banana
50g/L Potato (cooked and mashed)
3-5g/L Gelling Agent
950ml/L Distilled Water
Directions: Puree the Potato and Banana in a blender with some of the distilled water. Mix all the ingredients together and check the pH. pH should be around 6. The P668 media is usually self adjusting, but adding the Banana and Potato can throw off the pH. Adjust it if needed. Once that is done bring the mix to a rolling boil. Then flasks can be filled and autoclaved.5g/L Sugar

surface disinfection
Surface Disinfection
In order to disinfect your working surfaces, you may use either chlorine solutions, or alcohol. I prefer not to use alcohol, due to the fumes, expense, and flammability. It is much easier to make a disinfection solution in the following manner using chlorine bleach.
Using a measuring cup, take 2 parts (by volume) of 5.25% sodium hypochlorite bleach. Add to this 24 parts of distilled water. Mix thoroughly. Add to this 2 parts of household vinegar (5% acetic acid). Do NOT add the vinegar until the bleach has been diluted by the addition of the water! This solution is then added to a spray bottle. The solution is applied liberally to all surfaces that require disinfection; use of hand towels (inexpensive white dish towels from a discount store are perfect) to mop up the excess and wipe down surfaces is recommended.
When finished with the solution, unscrew the spray head, and pump clean water through the sprayer. There is no reason to clean the reservoir; as long as the bottle is tightly sealed and refrigerated while not in use, the solution remains stable for at least two months. However, the solution will corrode the working parts of the sprayer if left inside the pump, so flush it by pumping plenty of water through it.
