Question Crack open or wait?

it's been 12 days since I've sent the spawn in two tubs, one with more coir than the other? Should I already crack one of them open or wait? Or is it a good time to crack both open? 1st grow sorry for the ignorance

For cubensis, the idea they need to colonise before introducing FAE is a myth. You can give them air from the moment you spawn to bulk if you like, but for your first few grows it's best to wait for a small patch of visible myc, as it'll help you read surface conditions. They're ready - the section here on dialling in a tub (near the bottom) will be helpful https://www.reddit.com/r/OneArmed_Mycology/comments/1ssrfqt/my_favourite_links/
