Hi Filipe
Rootmaker don’t have any European stockists. I was fortunate to hear about them before I last took a business trip to the US and picked up a couple of their seed starting trays. Here’s some guidance on European equivalents:
For seeds
- The only choice is air pot seed trays AFAIK
For pots
- airpots, the original and most expensive
- fake airpots, mostly sold on ebay
- Ercole air pots, reports suggest there is still some root circling at the bottom of the pot (cheap on eBay)
- Idel Vinci, I expect root circling at the bottom to occur also due to similarity in construction with the Ercole (recently available on Facebook marketplace in the London area)
- fabric bags, ‘root nurse’ ‘root doctor’ ‘root pouch’ are all brands of fabric potsand there are other less well known brands/versions
Alternatives
As others have suggested, anything with a lot of holes in
- Hydroponic baskets
- Pond baskets
- Collanders
- Mushroom or catering trays
Happy to discuss further if helpful - I’ve got a few of each of those I mentioned as I’m conducting an unscientific trial into which is ‘best’ and why.
