Shotgun Monotub?

Ive been thinking on the use of Perlite as a humidification source and how to incorporate it into a monotub setup. I was wondering if this would work at all. The moisture would be able to escape from the sides which could be left a little looser than normal. Feedback much appreciated. Excuse the shitty paint mock up.

Over thinking things a bit, IMO. Not that it wouldn't work, just more work than necessary and defeats the purpose of a monotub.
The water bit at the bottom is concerning, however. You don't ever want standing water. The perlite just needs to be moist so the high surface area produces humidity.
EDIT: come to think of it, if the perlite is mostly covered by a plastic bag that is held down by a few pounds of substrate, there wouldn't be a whole lot of airflow to wick the moisture off of it. You'd just have the humidity that a normal monotub would provide.
What you could do is make a SGFC and put smaller aluminum trays of substrate in it.

One can never over-think or over-plan . However Ive seen mixed ways to use perlite. Some say just leave it moist, some say around 1/4 the depth of it filled with water so that it continuously wicks up to the top perlite and then up and away.

I would strongly recommend disregarding the latter people's opinion. That is wrong, entirely unnecessary and only adds another vector for contamination. Perlite is a mineral, like rock, and cannot wick anything up through capillary action.

SGFC and Monotubs perform just fine the way they are. But that's not saying people who think out side the box don't improve things. Good luck.
Oh, by the way, I'm doing exactly what you are doing. I find my first flushes out perform any subsequent flushes after that, and I take the substrate out and place it in the old SGFC. I have the whole block of substrate resting on some baskets.
Perlite, Trashbag, baskets, Substrate. Keeps it from drying out, flushes are nothing to write home about. But it's better then getting rid of perfectly good substrate.
I'll post a pic in a min.

Like Jenkinz said - disregard perlite wicking water up and like he said you want moist perlite not standing water.

GimpCollector, it doesn't look like you have any space for the humid air the perlite produces to reach your sub. If there's a plastic liner in the way, it's only place to go is out the bottom holes of the tub and into the room. The sub itself is producing the humidity necessary, like it does in the mono. Not sure what you're achieving here. Or am I missing something?

Thank you for clearing that up, makes quite a bit of sense that its just another contam worry.

I would love to, but currently tubs make more sense as per my space issues.

Thats pretty much exactly what I was planning on except that I would also do the first flush in the SGFC. If I may ask, do you have any indications that putting them in there raises the moisture by any significant amount?

For sure standing water is no good. Asking for a stinkin mess to blossom. My SGFC is in a bath tub, I just fill the tub up to the perlite layer then drain the tub, this gets all that perlite nice and wet.
I haven't blocked all the perlite off, on the sides you can see I left the bag pulled back, same on the bottom. Haven't had a problem. Fruits are big and fat, so FAE is happening, as they are not spindly.
I'm not saying it's perfect, I was just reinforcing dudes Idea that it can work. It's not the best, but I don't like throwing away good substrate.
The bag is on top of the perlite. I get fruits, and it works fine for what I need it to do.

You could add a casing layer. It really shouldn't be necessary though.

Oh for god's sake, just make a SGFC and put some trays in it, or put one big substrate in a bag inside.
Or make a mono, which is more effective for fruiting large bulk substrates IMO.

Thanks for all the feedback guys. I havent done a monotub yet and its my next adventure to embark on, I was just trying to see if I could migrate some ideas from my SGFC grow to this next one. Looks like I shouldnt have any moisture problems, and if I do there are easier ways to accomplish it.

Yeah Mono tubs rule. SGFC are a bit cumbersome, once you see the ease of a mono tub you'll be happy. Like I said I only used my old SGFC so I could squeeze more boomers out of good substrate.
My first flushes are always full canopy, so waiting on a less then flush isn't worth it to me, as I could be cooking another tub while utilizing the SGFC.

Gimpcollector are you dunking your sub between flushes?

Follow a tek EXACTLY the first few times. Learn the basics. If you still feel you can do it better after a couple grows, by all means experiment. I all but guarantee that you'll realize, just as I did, that everyone does things a certain way for a reason. There are plenty of other ways to do things, but the select few that are used most have been proven time and time again to be the best.

Makes more sense. Try skipping the perlite next time and see what happens. It's probably not necessary and will save you time and mess. I fucking hate that stuff. Gets EVERYWHERE.

On the monotubs I cut the first harvest, mist for a few days, then dunk. And put it back into fruiting. 5oz from first flush vs 2 or 3 for a second, just not worth it to me.
