Experiment 28. 08. 2019: a repetition experiment⌕ Will repeating the same experiment lead the same results?
In the weeks leading up to this experiment, HOW samples have not been developing very well. This experiment focuses on verifying if repeating the conditions of successful samples will give the same results. Additionally, mycelium forming
direction and structure are tested. 8 medium Petri dishes were prepared, using HOW from all dried batches laying around at this point, in pairs. All 'A' samples were mixed, meaning that the ganoderma mycelium spawn is mixed homogeneously with the dried HOW. All 'B' samples were layered, which means that the mycelium spawn is laid at the bottom of the dish separate from the HOW substrate: The batch samples from B.0.1 and B.1.1 grew the same as before. B.3.1 and B.3.2 were newly introduced and behaved differently in the repetition conditions. This could have to do with the composition of the dried HOW. Mixed samples became slightly curved towards the top, while the layered samples formed flat. A cause of this could have been that mycelium always forms its net upwards, thereby constructing a denser mass and tension in the upper part of the dish. |

Experiment 16. 09. 2019: colouring attempt 03⌕ Can the HOW material be coloured?
This experiment focuses on testing if different colour dyes preserve during the mycelium forming stage, and if colour dye hinders mycelium forming when the HOW substrate is present. 15 medium Petri dishes were prepared; 10 dishes containing HOW substrates from all batches laying around at the time, and 5 control dishes. The red and blue silk dyes were poured on top of the dishes after the mycelium spawn and the HOW were mixed. As yellow dye, turmeric powder was mixed homogeneously in the mycelium control dishes. The red silk dye preserved during mycelium forming in most situations. The blue silk dye was decomposed during mycelium forming, the colour dissapeared until the end of the process. Of the 3 yellow dye control dishes, the C sample didn't grow. This experiment concluded that colouring the HOW material is possible but the exact conditions in which this must happen are yet to be researched. |
