Anyone tried this - do they rot down easily enough for the root to get through? Consistent spacing for some things but you could cut them up into cups for others. I'm thinking of root veg like beetroot and parsnips etc.

I never found them worth the bother as you can pack so little soil/mix into the individual cups that the seedling very quickly outgrows it and you have to fuss with it again. Best to just find something larger to start with and leave it a bit longer. We all start out with great intentions and soon find we haven't time left to spare the fiddly bits. I've just drilled holes into the bottoms of some 750ml yoghurt containers and filled them with potting mix. They'll be used to start more leeks which can develop some lovely roots without taking extra time from me.

I did try this with the cardboard container you get to two ready to eat avocados in.  I think I sowed courgette seeds in them but I wasn't very impressed - perhaps I got them too wet but they went a bit mouldy and the seeds didn't germinate, unlike others I put in normal pots.

I certainly wouldn't use them for parsnips because they are likely to fork when the hit the bottom, try loo roll centers instead.

The deep brown trays my big field mush came in (Sainsbellies) are perfect for my window sill seeds. Just make holes in the bottom and 2 fit very nicely thankyou into my cheap plastic propagators.
Must buy more mushrooms...they're on offer.....

Egg boxes are to fiddly for me to try and plant things in but I find them pretty darn good for chitting seed spuds at the time of year.
