Growing under lights in a shelf type system is a good way to get a collection going.

Wetting things down can mitigate dust particles. It's why I use water to wash my sand. Silica in your lungs is not great.

You can get grafted Peyote to flower under 1 year too as you can control the temperature and can avoid the dormant period. We ran grafting competitions in this forum years ago.

Mostly_Harmless got one to flower from seed in under a year from memory.

Very nice! Much respect 



Also sorry guys for going off topic.
I wanted to sift some clay US soil (PNW to entire West states)
and get it super fine. So it'll look like this!
Even cracking the soil as it grows!

That'd be so cool, you guys could pull it off! Especially the soil
gurus here. I wanna try that next season.
Though me experimenting would have to be careful and willing
to risk losing those.
That soil can be very muddy, but similar to
their natural home. 🌱🌵
