First time grower quations

1st time grower here with some questions:

I recently purchased 2 2IB bags from GROMAGIC and 2 3IB bags from NORTHSPORE as well as 2 10ML syringes (Stargazer and JMF)

I'm planning on inoculating 1 2IB bag with 4ml and 1 3IB bag with 6ml for each syringe/bags...Is this suitable for technique?

After inoculation I'm planning on storing all the bags in my closet on a shelf (Or should I purchase totes with lids to store them for colonization?)

After colonization I'll move the bags to a corner in my apartment with indirect sunlight..

I also purchased 1 monotub and plan on storing 2 bags in there, the other 2 on a shelf in the open.

Do I have to worry about contamination after colonization during fresh-air exchange? Should I cut a small slit in all the bags near the top of the cake or cut the whole bag and use as a hood?

How often do I spray the inside of the bags with water to keep the humidity high?

Any other tips/tricks I should know of before starting?

Thanks in advance!!!!
