Mono tub condensation, helpful? Bag or no?

I know some people like to use black trash bags in there mono tubs, some use them for clear mono tubs to fight side-pinning others like to use them so the condenasation falls back behind it so water doesn't pool inviting contams.
I did 6 mono tubs for an experiment. 3 with bags 3 without. I want to see if the excess water from condensation makes a difference in substrate hydration.
The monos have been in incubation for a few days now and one thing I've noticed with the bagless monos are they seems to pull from the sides and tighten up, the condensation falls behind that gap. I'm not certain if this is good or bad, but my money is on - not so good.
However, I reduced the amount of polyfil in the fae holes, not the c02 holes to allow more FAE and maybe most of the water will be absorbed by the sub and the rest will evaporate..
Someone once said in a thread to not use a bag in the mono because the water will pool behind the bag, where nothing can absorb it and it invites contams. This is my first time using clear tubs for monos, and since they are clear I can definetly see moisture build up between the bag and the tub it self.
So, What is everyone elses opinions on condensation in mono tubs, bags or not? And explain why you think your answer is best.
Also. Would drilling a few small drain holes on one end and elevating the mono to drain that excess moisture out be overboard?

I hate to see a good question get bumped to latter pages unanswered, though I'm probably not the one to give advice on this.
I've never used bags in monotubs before. I always use opaque tubs, so I've never needed them. I used a clear tub, once. I just got a cheap can of black spray paint, ran a strip of masking tape right above the area where the top of my substrate would be, and sprayed from the tape down, including the bottom (on the outside of the tub). Pull off the tape for a nice clean line. It blocked the light out nicely, while still allowing light in around the top where I needed it.
If your substrate shrinks too much and pulls away from the sides, you can also pack some dry vermiculite around the edges to help prevent side pinning.
I can definitely see where water condensation running behind your bag could become a problem, if you use them. Nothing breeds contamination like stagnant, pooling water.

Danm I just did my first mono with a bag in it. Well I just hope this is not a serious problem and I'll get a flush with no contams. I had some time to think about alternatives to a bag. The simple solution would be to use some duct tape or something like that on the outside of the tote. Perhaps spray paint would work as well.

I'm not questioning whether or not a bag will work, All im saying is there has to be pros and cons for both ways.

well yes condensation will come down and puddle behind the bag but it's really a matter of choice.

take a look clear tubs and bag used, speaks for itself.
I don't think the bags were a major factor in the success of those grows.

if you are worried about pooling water at the bottom, under the bag, you could line the tub with half an inch of perlite i suppose, and set the bag on top of that.

Just drill a small hole for the drainage.

I was looking up the relevance of bags and found a few monotub tutorials that recommended you tape the bag into the tub. I think this is how you are supposed to prevent pooling behind the bag.

bags also make it really easy to get the sub out and back in the mono when it comes time to dunk for your 2nd, 3rd etc. flush
but yeah do what hybridprx suggested and drill a hole for drainage.

overboard.
Someone once said in a thread to not use a bag in the mono because the water will pool behind the bag
it coulda been a 15yo kid.
as long as the tub has plenty of fae you wont have to worry about contams, the pooling behind the bag doesnt matter.
the fact the bag shrinks with the substrate is a good thing, the substrate wont be exposed on all sides and wont dry out, all the moisture will have to escape the substrate through the casing layer keeping your casing layer from drying out. as long as your holes arent packed too loose towards the substrate level you should get a nice even pinset. i pack all 4 bottom holes on my monotubs moderately loose and the top two holes extremely loose, the fresh air pours in from each side of the tub but the mass of the substrate along with the container its in keeps the humidity up towards the substrate level during primorida formation.
it really, doesnt.. matter.
think of it as your substrate being wrapped up in a warm cozy blanket during your grow.

so you dont think having pooling water under the plastic (from water running down the sides during colonization) will pose any risk at all for contams?
i recently lost a tub to trich and when i went to take the plastic out from the tub i had a pretty substancial amount of water under the plastic. im not saying that was the cause of the contam. but that water probabally sat there like that for two weeks or so. I dont think any standing water is a good idea at all but you've had alot more sucess than i have.
Large Dose- do you usually have pooling water under your plastic when you remove your subs to rehydrate and still have the sucess you do?

do you guys tape your bag up against the side?

No for me too. Like large dose said, the substrate pulls in the bag as it shrinks, which helps prevent side pinning and keeps the moisture in.
