The Charles Dowding 30 cell medium size seed tray developed by Charles Dowding (30 cell)
The middle brother of the Charles Dowding range is the 30-cell. With a smaller footprint than the 60 cells but with similar cell sizes it is a great tray for those with a smaller garden or for the plants you only need to start a few off.
As with the entire Charles Dowding tray range, you can use the trays to extend your growing season and grow more efficiently with less space.

Charles has been growing vegetables for more than 40 years and shares all his knowledge for free on his YouTube Channel.
His growing method is based on no-dig gardening and cropping loads of vegetables in a small area by intercropping and starting almost every plant in a module tray or plug tray.

The cells of the Charles Dowding trays are tapered to help with quick transplanting and also have large holes in the bottom to help with water drainage and popping out the seedlings.
They are also sturdy so you can hold your tray with one hand while using your other hand to take out the seedlings. Read our Blog about the trays to learn more!

Why would you use the Charles Dowding module trays?
– Long-lasting with a life expectancy of 15+ years
– Sturdy and easy to hold with one hand
– Large holes to pop our seedlings
– Roots are air pruned to support branching

Gardeners in the UK can order their CD30 seed trays through our oversea partner Containwerwise UK here

Best seed tray ever

The CD sowing tray is exactly what I was looking for. The hard plastic makes the trays almost indestructible so they last a very long time. These seed trays are what you want!!!

Top to sow less to prick out

Like the CD60, the small trays are sturdy and great for seeding. Easier to sow small amounts when you don’t need a large tray, but to transplant seedlings to these trays is quite prickly in size, especially if the root is already a bit longer. Then I prefer the cell size of the 40-cell trays.
