Does this work in practice? I think cardboard is too durable for this.
it works really well. i did it several times. the cardboard will get soaked over time until it nearly decomposes by itself. you will need to be careful when lifting the pot to plant it into the garden, but the cardboard wont be a potent barrier by then anymore. the rest will be eaten by earthworms etc. who really love cardboard.
I just did a bunch of seedling starts the same way and it worked perfectly. The cardboard was soft enough for roots to break through.
This is so smart!
You can make pretty good ones using layered newspaper. Or any paper that doesn’t have something nasty in it. Using a cylindrical glass or similarly shaped aid. I’ve used a big vitamin bottle with the top sliced off. There are a bunch of tutorials.
Only trouble is, if you’re just finding out about this now, you won’t have enough of them saved up to use until next spring!

i recommend a worm composter. this way you would collect the rolls anyway (because worms like them) or working as an educator ;)

lemmy needs a remindme feature :D

“remindme” on The Discussion Forum Which Shall Not Be Named was just a bot account run by a third-party. The Fediverse not only has the same, but has several to pick from. (I say “the Fediverse” rather than “Lemmy” in particular because the first one that comes up in the autocomplete is actually a Mastodon account, @[email protected].)

Not at the rate I’m pooping
You need a bidet.
I’ve been using egg cartons which are working great but I need to try making some of these too!!

I tried egg cartons one year but the plant roots really struggled to break through the bottom, and my plants were pretty stunted.

Maybe I’ll try paper cartons next time :p

Seriously though, is that not a problem for you? Kinda wonder what you do differently.

This is my first time growing from seed and I haven’t transplanted yet, but my friend has been using them successfully 🤷🏻‍♂️ she’s the reason I’m doing it that way (and me having no money lol)

It may depend how sturdy your brand of cardboard packaged eggs are I guess

I’ve done this and the, results were fine, but I didn’t have a control group to compare.

In fact, I need to do this again right away or suffer the indugnity of buying actual chili plants

PLEASE DONT EVER DO RECYCLING-PAPER INTO SOIL!

There are a lot of badly chemicals in recycling-papers!

not in germany, there are not a “lot” of bad chemicals in recycling paper, since the limit values are very strict. however i don’t know how other countries handle this. i will put an edit in the original post.

This is a good idea, but I might use more durable paper towel rolls cut in half instead. All the world’s toilet paper is soaked in a special form of PFAS/forever chemicals that make paper much more soluble in water, or less likely to stick to equipment during manufacturing. That chemical can bioaccumulate in plants and soil, contaminating it for decades, unfortunately.

Toxic ‘forever chemicals’ found in toilet paper around the world

Research finds waste flushed down toilets and sent to sewage plants probably responsible for significant source of water pollution

The Guardian
the pots are made from the recycled cardboard part in the middle. pfas in tp are used to make the paper more easily flushable, so i doubt it’s used in the part that wasn’t meant to be flushed anyway. tp however wouldn’t be a good material, because it’s not sturdy enough and almost everytime bleached. however i saw that tp in some countries doesn’t have the sturdy cardboard part in the middle and now i realise that you probably talk about the cardboard in paper towels because we are talking about the same material…
Oh yup, I meant the brown middle part in paper towel rolls!
