Seed Trays

       
These are really deep - nearly 10cm..
       
These are approx 5cm deep by 4cm. really good size for starting hardy annuals eithput using tons of compost.
       
Thrse are the smallest module size I got - perfect for snaps, poppies, clary sage, Bupleurum etc. This is the same size as my most used chesp plastic module trays. 5cm deep by 3cm square.
       
These are now going to pot heaven.

I didnt actually get the Charles dowding ones - they were too shallow for me. I got the deep trays.

I'm not using gaffa tape anymore to do repairs! I got lots of cuts from broken plastic... so Im binning any that have started to deteriorate.

There are several options on there... I use capillary matting in drip trays which help to keep everything moist.

I also grow in large numbers - Even before starting the cut flower plot I would rarely sow only a dozen seeds.
I planted out over 100 snapdragons last year. They stay in the green house for a long time so space is a consideration too. I've single sown a full tray of poppies yesterday, lots of autumn sown hardy annuals etc go in now. They dont need huge modules. Odds/eveb trays are not an issue for me -I plant extras for losses and expect gaps.

I hope some of the photos are useful for some - it is difficult to show size on a photo.
