Great source of spores.

I have had nothing but good luck with Eden.

Finally! What a relief.

My spores took 2 weeks to start showing signs of mycelium growth. I was worried, but not now! These things took OFF after week 2! Mycelium is growing at a crazy rate once it started. I'm almost 30% colonized after a week. Shake is coming soon. Thanks Eden!

Robert R.

No colonization after 2 weeks, but I'm being patient and am hopeful the heating pad is helping. It was sub 70F

B+ Spore Syringe (P. Cubensis)

Is starting off good

Ordered this with 2 other syringes and those other two never started to propagate. This one started showing some growth after about 20 days of observation.
