As a beginner, I struggled with humidity, c02, etc. Fanning and misting, at least in my environment led to a lot of infection. Enter the Mushroom Ecosphere.
Now I can dial in humidity, C02 levels and temp and fresh air exchange, made all the difference went from blocks getting infection and/or producing small flushes to excellent yields and multiple flushes.
Its really not a lot of money when you factor in the learning curve and losing things that take a month or more to get to fruiting stages.
I added an additional fan to exhaust c02 and upgraded the humidity controller, but it wasn't really necessary until I had multiple blocks fruiting at once, then the C02 went off the chart..lol.
If you just get this to start with you can save yourself a lot of frustration and money in tubs, etc. Just my 2 cents.
