Product information "Sowing & growth medium SBL-C"
These growth media are products of the highest quality, which are constantly being improved. They have been and continue to be regularly tested in practice at universities and colleges. After production, the growth medium will be subject to strict quality control.
For the experienced user, the use of ready-made growth media means valuable time savings and cost-effective working. Beginners are spared unnecessary sources of error.
The accuracy of a kitchen scale is sufficient to weigh even small quantities
Additions of natural substances or active ingredients are fully possible
Directions for use
The required amount of powdered dry product is weighed out. If there are lumps, they are crushed with a mortar or with the fingers. The prescribed amount of substrate is slowly sprinkled and dissolved in 1l (in the case of 0.5l, half the dose, etc.) of distilled or demineralized, boiling water. It is stirred and heated until everything has dissolved: the solution is then transparent to translucent. The pH value does not need to be adjusted, it is between 5.0 and 5.5 depending on the substrate.
Additional natural substance additions or active ingredient additions are generally not necessary, but can be added. When using birch sap addition to the growth medium, no pH value correction is also required. However, some natural substance additions such as unsweetened pineapple juice make a pH correction necessary.
If insoluble or poorly soluble components (sediment) occur in the growth medium - e.g. also with banana puree addition - then the undissolved portion must be evenly distributed over all culture jars.
In practice, the following media have proven particularly favorable for the repotting (transplanting) of the germinated seeds, whereby the protocorms should be approx. 1mm large:
GD growth medium D incl. 25% birch sap or 5-10% pineapple juice.
SBL growth medium A incl. a homogenate (kitchen machine) of 100ml fresh pineapple juice with 40g solid banana fruit pulp per liter of growth medium.
SBL growth medium A and C incl. 10% fresh pressed pineapple juice.
With pineapple addition, the pH value must be adjusted drop by drop to pH 5.1 with salmiak spirit*. It has been shown that freshly prepared natural substance growth medium combinations are preferable to similar prepared preserves. Birch sap, pressed pineapple juice and pineapple-banana homogenate are very well preserved when stored in the freezer (1-2 years).
