I lived in Nicaragua and had a few hundred banana plants for about 5 years.  What I learned from the locals regarding pups.   You only ever want to have 4 stalks at any one time, and in fact most of the time you only want 3, and you want them to be staggered in size.  You don't want any two of your stalks to be the same size.   So for example, you will have your tallest stalk with developing bananas, your 2nd stalk, and then your 3rd stalk.   Keep eliminating your 4th stalk until such a time that your 3rd stalk is pretty big ( I waited for 6 feet).  So then when the 3rd stalk hits 6', you let a new stalk come up, but shortly after that you will be harvesting your bananas from the tallest stalk, and then immediately cut down that stalk and go back to having only 3 stalks.  If you do it that way, your 2nd stalk will be flowering while the 1st stalk is finishing off the bananas.  You can be harvesting about 2.5 times per year.   All of those extra small stalks are just stealing energy from your 2nd stalk and preventing it from flowering.   Just keep chop/dropping that 4th stalk until the 3rd stalk gets big.  There should be a mess of dead stalks under your plant, and once you harvest the bananas, cut that stalk also and let is decay under the plant.  This creates a lot of mulch and the stalks are almost entirely water.

The other thing is to learn to recognize the difference between stalks, and hijos(children).  If you think of indeterminate tomatoes... a stalk will be like a branch, but a hijo is a sucker.  The way you can tell the difference is at the very base of the plant.  A stalk will develop out of the same base as your other stalks, but an hijo will develop it's own base.   So if it is all stalks, the top view of the base will look more like an 0 (an ellipse), but if it is a hijo, it will look more like a number 8.  Hijos should always be removed.  You can take a shovel and basically split between the number 8 and create a separate plant if you want to give it away, or you can just dig it up and drop it to die.  I never really counted, but I would guess that about 50% of the time something comes up, it will be an hijo, and 50% a stalk.  Hijos can get really out of hand if you don't dig up the base of it, and they just take so much energy/space away from your main plant.   For instance, we had areas that had thousands of wild banana plants, but the hijos developed so close and so often to the parent, that you never see wild bananas develop, just the plant.   I think banana plants want to propagate using hijos, and producing actual fruit is a secondary means to reproduce.  Kinda like if you don't trellis and  prune indeterminate tomatoes,  you may never get fruit as the suckers will just develop roots and grow and compete with the original plant.

I've been hesitant to farm in Canada, for a variety of reasons, but a greenhouse like this seems like a dream come true. Congrats brother.

As a canadian im so proud you have shown to the world where there is a will there is a way❤❤❤❤

Please show us the ins and outs of how you built your passive solar greenhouse. What considerations you made, how you figured out how to angle it from the sun, what you use for  solar mass, what you built out of and all of it please!

..." it warmed up abit, its only -22°C ...

😂...ohhhhhh caaaanada🎶🎵

This is awesome! With the amount of land we have here in Saskatchewan there's no reason we can't have more of these and stop relying of goods  coming out of country.

Imagine! You could make the most expensive tropical crops... in the least tropical place? TAKE THAT SHIPPING AND HANDLING  😂🎉

We need a million more of you, in Canada!  :)

What a beautiful greenhouse! You must be so beyond proud you not only built it, but are creating food for your family, and you know exactly where it came from, what sprays if any are on it. What a dream setup. Just lovely.

Damn! I am so impressed and this has given me “food for though” for building a better greenhouse for growing in Canada. Well done!!!

Hmmmmmm! 💡 I imagine all the closet mad-scientist passions re-awakening in the hearts of guerrilla gardeners of the North with their impossible dreams and fresh possibilities that your videos have inspired! Thanks for sharing… Blessings from Manitoba 🦬

You’ve done so much more than build the greenhouse but that was the hook for me. This feels the awesome major milestone.
I’m celebrating this grand thing that you guys are doing. It is so hopeful for fellow Canadians.

Truly amazing 👏.  We should be doing this across Canada especially in the far remote communities up north

Awesome,  finally Canadians can have fresh food year round ❤👍🕯

Sooooo proud of you and your Canadian bananas Arkopia!!! Amazing work!! 😍😍😍

Fantastic! What an inspiration to promote self sustainable healthy living, & environmentally friendly, so no comebacks. Keep up the great work & sharing.

You are absolutely nuts. You really have gone Bananas. My absolute respect coming all the way from BC.

This is the right way to do it.  None of those nasty venomous tropical spiders.

Incredible.. Great accomplishment.. Greetings from Alberta...

Awesome and Very Impressive! Good on You!! I'm in BC and wish you continued success with your labour of love!
