The sturdy 40 cells Containerwise long-lasting Propagation Module Trays

The eco-friendly sturdy 40 cell seed tray is designed to fit most seedlings, from flowers to vegetables to fresh herbs.
Due to the use of strong, recycled, and recyclable materials, the trays will last up to 15 years, so you will not have to buy new module trays over and over again!
Personally, the 40 cell seed trays are our favorite and most used tray to start our seeds.
Because of the big 4 centimeter cells, you can fill this tray with loads of compost to start almost all seeds. due to the bigger cell size, the compost does not dry out as quickly as can be with smaller cell sizes.
Most seedlings can grow big enough in this seed tray to be planted out in the garden without the need of transplanting them to bigger pots first.

Module trays are great to extend your season by starting out early indoors, or in a greenhouse. Here in The Netherlands, we can start a few months earlier using these trays!

All Containerwise trays we offer are made out of recycled hard plastic to ensure a long life of about 15 years. Because of the sturdy material, you don’t have to worry about tearing or breaking these trays.
They are also UV-Stabilized this makes sure the plastic will not degrade over time.

After a long search found this great seed tray. Very sturdy and durable, and super convenient because of the large hole at the bottom. You push your seedlings out very easily without damage.

I received the seed trays today and have not used them yet but I am pleasantly surprised. You can see at a glance that they are of excellent quality. Super sturdy, the cells are nice and deep and very nice that all trays are the same size. I can’t wait to start using them. More than worth the money.
The delivery was fast and kudos for the packaging. This is how it can be done….no unnecessary plastic padding.

Very solid material!
I bought the 40 cells seed tray and the Charles Dowding Module tray each with a bottom water tray and also bought a Propagator with lid and air vents to test out. I read somewhere that Charles Dowding trays can last up to 15 years. I believe that now that I have had one in my hands. Very strong! Forget those cheap trays and invest in these! And extra plus points for the packaging material: no trace of plastic, everything went straight into the waste paper.
