Judging by the posts I see on allotment and vegetable growing Facebook posts, we are all trying to reduce our use of plastic, me included. However, there are some things that are just best made in plastic, what you don’t want is for it to be one-off plastic.
I have tried many types of seed sowing trays, containers and pots over the years. I have root trainers which I find very useful for cuttings, sweet peas and broad beans but they are very flimsy and most have broken. Two years ago, I found Containerwise through Charles Dowding and bought some of their seed sowing modules. I don’t use the size CD uses but one size bigger. They are fantastic, made out of rigid plastic and said to last 10 years although I think they will probably last longer.
When I was looking for a replacement for the root trainers, I found these deep propagation trays and these. I am going to get 1 of each to try them out this year and see what works best for my needs. I am also going to try these rubber root trainers that are supposed to last a life time.
I am also going to try these silicone seed modules that look and feel just like my silicone baking trays. They are reputed to last a life time and it is supposed to be easy to get the seedling out of the tray.
The downside might be that they are a bit floppy to carry on their own so will need a tray underneath them and they are more a transplanting rather than seed sowing size.
What do you use?
