[Technique] Sporeprint to Agar

Technique

Hi dear mycologists

as for a couple of weeks i've decided to step into this beautiful field of mushroom growing. Got some sporeprints, cooked my agar (500ml water, 10g honey, 10g agar powder, 10g potato flakes). Poured the ketchup cups (16 pcs.), introduced the spores, worked sterile (DIY SAB, ISO 70%, gloves, flame sterilizer, scalpel).

out of 16 plates, 2 have signs of germination. One of them seemed suspicious and milky (see attachment) the other one looks more "normal" growing.

Spore introduction: 03.04.2025

first check: today, 09.04.2025

+++++++++++++++++++++

any general advice?

side questions:

My poured agar plates have a lot of condensation... i really try to pour them "later" so they don't condensate but yeah... any advice on that one?

And what about the spore scraping? any ideal amount i have to introduce to agar?

Thanks and cheers
