Anyone do this on their own? I was thinking of buying a prebuilt kit then doing it on my own without them after I get the hang of it. I'm wondering if I'm being jewed though the kit is ~$100. Does this seem high? Apparently they skip a few steps with it and it only provides up to 3 batches. "By providing fresh mushroom spawn with our magic mushroom kits, we save you up to 2 weeks of waiting time before you can start growing." Would love to hear about anyone's experiencing growing their own.
