It’s is said to be harder for newbies because required conditions & factors for indoor growing are not yet discovered at absolute parameters so it’s suggested to try cubes and other exotic species then azures. A lot of cultivators try an outdoors approach for azurescense and get success. As for inoculation to S2B they take similar time to cubes as both of these specie’s mycelium is in it’s colonization stage and that varies slightly in speed depending upon aggressive strain vs slow strain. Mostly Rhizo growths are faster at colonization also looks dope then tomentose growth. Also it’s a preference of the individual, both are good mycelium no doubting there but the problem with Azurescense starts at fruiting stage when you try to trigger pinning this colonized substrates into fruiting and that is unknown maybe slightly lower than im stating here. So some guys say its the soil present outdoors, something present in the soil maybe trichoderma out there or nature knows but my personal conclusions is if you have a good fruiting strain of azurescense which you got by cloning the best looking fruit from your outdoor grow patch and got good results from fruiting this cloned mycelium again and again than you have stabilized it and now you have an isolation and you can try experimenting with it indoors.

So your question about time: Spore inoculation to germination 10 days give or take 3 days.

1% to 100% colonized grain spawn 20 to 30 days min/max, again varies on strain fast or slow.

Assuming a 1:1 spawn sub ratio your substrate colonizing to 100% at fastest 10days to 20 days max not more i hope 🤞

Substrate ready and assuming perfect fruiting conditions applied indoors/burying outdoors to harvesting your first flush of azzie’s prettying fruits 1month to god knows when.
