with no holes, how do you administer fruiting conditions? just fanning?

I don't use holes in my tubs anymore.  I leave the lid cracked about a half an inch during the day, and close it up at night.  When I say I "leave the lid cracked" I mean that instead of putting the lid on the tub so it's closed, I move the lid off center by about a half an inch.

The way my lighting is set up, is the bulb above each tub is about 6 inches away.  This creates warmer air inside the tub than outside the tub, which in turn creates convection currents within the tub.  The warmer air exits through the 1/2" opening on one side, and as it exits, pulls fresh air in through the 1/2" opening on the opposite site.  So during the day it gets, more or less, constant fresh air while still maintaining a very high RH (RH is controlled by the size of the gap created by having the lid offcenter...which I can easily make larger or smaller by simply moving the lid closer to or farther from being completely closed).

I've stopped modifying my tubs for a couple of reasons, the first being that once I've modified them with holes and whatever else, they become kind of single purpose, in that I can't really use them as regular tubs anymore for things like storage.  Second, they look weird as hell and are hard to explain to people asking why I've got tubs with holes all over the place.  Third, I've found great success not putting holes in them...in fact, much more success than I had while putting holes in them.  Fourth, moving a lid back and forth is a lot easier than messing with "polyfill density".  What I mean is, it's hard to accurately measure from one grow to the next "how dense the polyfill was" the last time when you had a good grow.  The offcenter lid method is easily measurable...in that you literally measure how far from centered the lid is, and it's easily repeatable.

I give a good fanning just before I seal the tubs up at night.  I mist whenever I see that things are dry or on their way to approaching being dry.

Haha, thanks very much

Looks wonderful! Definitely trying out a tub with no vent holes next time!

Thanks and yeah, it's definitely worth giving it a go.  A lot less to mess with (IMO) and easier to get right (IMO).
