The temperature in the grow kit and grow bag should be right for the magic mushrooms to grow. Make sure that the kit stays between 18°C and 29°C (23°C is optimal), also at night. When the temperature is higher or lower than this, the mushrooms will either grow very slow or not at all. Eventually producing less mushrooms than could be expected.
Do not put the grow kit in direct sunlight, because it will be too hot for the mushrooms to grow and the substratum will dry out, not producing mushrooms.
When the mushrooms are almost mature, pick them right away. In the manual is written how to recognize ripe ones.
When you pick them too late, they will drop their spores. This will make the contents of the grow bag color black as you can see in the picture.
This is of no effect to your health or the trip, but the energy used for this to happen, will be wasted and you will produce less mushrooms.
