Mono Tub Question

I'm making a couple mono tubs tonight and I have a question for you guys. I think I'm going to line the bottom of my tubs with a black trash bag, my question is do most of you guys tape the bag in place or not? Thanks.

No.
I drape an over-sized piece of black plastic in the tub, then carefully fill the tub with bulk substrate and spawn, then level it out ... then I take a pair of scissors and I trim the plastic fairly close to the top of the substrate.
You want the plastic to conform to the sub and attach to it. Taping the plastic to the tub would defeat this.
Kind of hard to visualize ... but you'll get it.
Good luck.

Ricos got a lot of experience and his way works for him. I think most people here do though. No offfence or anything rico, you got a white thumb , just trying to answer his question.

No worries lcks.
I have used tape to hold the plastic in place while I've filled the tub and then removed the tape. Then developed the ability to fill the tub with the plastic just draped in place.
lcs, do you leave your plastic taped to the sides of your tubs ? My substrate shrinks a lot as the myc. eats it and pulls moisture from it during fruiting and the plastic at that point is adhered to the substrate.

Check out my msg's in my link. They're my first attempt at any sort of mono.
I taped all the way around. The first one is starting to pull away slightly from the tub. I didn't want water to drop under the bag though so that was my solution. My grow area doesn't get above 70 often and the humidity doesn't get below 70 often. I could almost fruit with out a chamber

I was also worried about water collecting under the bag and read that if you tape the bag it will channel the water into the myc and this is preferred.

My suggestion is to drain the crap from condensation (if needed) and mist/fan if needed. Your bag should stick to the sub as it shrinks.

I think that I have seen people tape it to the sides of the tub, but this might be more useful while filling the tub. ....I am thinking that you want it free to stay stuck to the substrate as it shrinks.

I get lots of condensation during bulk substrate colonization and also during fruiting.
I've had water (that dripped down the sides of the tub) pool between the plastic and the tub bottom .... and contaminate after the 1st flush (trichoderma ... standing water and no air exchange) so I know what you guys are talking about. The problem has been mitigated somewhat through drilling 12 or so 1/8" holes in the tub's bottom.
If you want to address side-pinning issues, don't tape the plastic.
This discussion has gotten me thinking ... How bad are my side pinning issues? Maybe I should try taping my plastic to the tub to direct the condensation back into the sub where it can get re-absorbed.
To re-answer the original question ... no, I don't tape my plastic. On second thought, maybe I should.
Final answer: no tape for side-pinning issues ... tape for excess condensation issues.

nope, the whole point of the liner is to keep that extra moisture out. The excess is supposed to collect down there.

I have seen inexperienced individuals have problems w/ side pinning due to taping. Many many times. If you know what your doing you can tape for the first flush. On subsequent flushes I pull the tape and push the bag up to the substrate.... But if I didn't know what I was doing I would say no to the tape.

Yeah, because it's such a problem to have pins growing on the sides of your substrate in addition to the top.
NOT

This scares me because my tub's are going to be on the floor and without poly fill in the 1/8" holes wouldn't contams have an open door into my tub?

Not really.
100% colonized substrates are fairly contamination resistant.
The tubs we use are not air tight or contamination tight.
100% colonization is key ... so is air flow.
When I get contams it is usually from moisture and no air flow. Also after a big harvest where your substrate gets ravaged and you can't get all the fruit flesh off the substrate (like the mushrooms are rooted deeply and don't harvest cleanly) ... that flesh can start to get funky ... mix that with lots of moisture from a post harvest dunk ... and trich. will often strike.
The 1/8" holes aren't in direct contact with your substrate ... your plastic is there.
Try and get the tubs up off the floor. I have put mine on milk crates when I haven't had shelves ... even though they are only 12" off the floor, I think it helps.
Good luck. Do something .. check it out .. you can always adjust and change it up the next time.
I'll bet you never thought this thread was going to turn into such plastic liner drama !

This is bad info. Do not tape the plastic liner to the tub. The plastic lining in a monotub is designed to shrink along with the substrate keeping side and surface humidity in check and you get less side pinning and more surface pinning. Also, the bag liner makes it easier to pull your substrate out of your tub for a dunk between flushes.

Holes for monotubs per the teks are 1 to 1 and a half inch(es) in diameter. With holes 1/8th of an inch, worry more about providing enough FAE and worry less about contaminates having a open door to your tub. HL

I don't see any side pins on mine, and I'm about to harvest here in a day or so. I may take the tape off after the first dunk to prevent further pulling away from the side on successive harvests.
The reason I taped, was to prevent contaminates from standing water. Drilling holes in the bottom is a good solution. I had thought about drilling the whole thing to SG specifications and just putting a liner in it for bulk. On my MSG, I stopped 4 inches from the bottom on the sides and left the bottom side untouched.
Also in reference to the 1/8th inch holes, Rico said that he would put them in the bottom of the tub, under the plastic not as a replacement for the standard monotub holes.

i never tape my tubs, only cause i forgot every time i make em 
as for water pooling down the sides, I crack a little drainage hole with a solder iron in one corner of the monotub to drain if need be.
I can see the benefits of taping, makes for a neater tub, with less stray kernals of grain going down the side as a vector for contaminates.
If i ever remenber to do it, I'd tape it while I make and mix to bulk, fold down sides to the outer and remove tape when done.
I also gaffa tape the outer tub sub depth to be certain of no side pins.

I do want to get them off the floor but counter space is really at a premium here. Milk crates sound like a great idea but I'm not sure how to get them, wonder if the supermarkets will give them to you if you ask.

use anything long as they are at least 2ft off the ground.
