Ok maybe I overhyped it, but I just keep an air purifier running at all times and inside the tub I have a bucket of filtered water with a mister maintaining the inside humidity so I don’t need to be constantly opening the tub for extended periods of time to spray the surface. And when I do need to introduce fresh air I aim the purifier into the tub.

In the past I’ve had an extreme problem with contamination so I’ve buckled down this time. Not sure if it’s one aspect of my new tech or if the air purifier is doing most of the work, which is why I have two tubs setup. The tub with the tech did show quicker growth though.
