How to find the right seed tray for you

How do you garden?

Most home gardeners prefer to garden when they have time and can’t be on top of it all the time. A bigger cell gives the plant more space and time to grow and also, more compost means that it can hold more water. That way you can garden when you want to and don’t have to be on top of it. Smaller cells are great for slow-growing crops or for a quick turnaround in the garden. They do of course require to be watered more often.

Why module trays instead of seed trays?

The cells in the module trays have our preference because of the ease of use when transplanting. And usually, when you start seeds in seed trays you will still prick them into module trays (something we do as well for lettuce and brassicas).

Module trays also help with keeping the roots of each plant in check. That way they can’t get entangled with each other and grow a strong root ball that is ready for transplanting outside.

What seed tray to get for growing vegetables?

As each vegetable grows differently we also use different seed trays for each vegetable. This list would become pretty long so please use the seed tray finder above to figure out specifics.

But as general help, Leafy vegetables like endive, corn salad, lettuce, and purslane can be started best in the 60 or 77 cell trays (+/- 3 by 3cm cell size).

Fruit vegetables like cucumber, zucchini, artichoke, bell pepper, squash, and tomatoes like the extra space the 15 cell provide (+/- 7 by 7cm cell size).

Cabbages like cauliflower, kohlrabi, broccoli, pointed cabbage, Chinese cabbage, red cabbage,  white cabbage, Brussels sprouts, and pak choi need some extra depth for their roots so love the 40 cell deep (+/- 4 by 4 by 9cm cell size). 

Root and tuber crops like beetroot, celeriac, radish, salsify, and Onions like spring onion, leek, red and white onions prefer the 40 cell tray (+/- 4 by 4cm cell size).

Crops like Peas, long beans, pods, string beans, green beans, broad beans also prefer some extra depth. The 28 deep or 40 cell deep trays are great (+/- 4 to 5 by 4 to 5cm cell size)!

What seed tray to get for growing flowers?

We start most of our flower seeds in smaller cell sizes like the 60 or 77 cell trays. If they can not be planted out directly after because they can not tolerate frost (cosmos, zinnia, and other heat-loving summer flowers) or because we have to start them very early in the season because the days until the plants start to flower, are very long (more than 90 days) we transplant them onto larger cell module trays like the 15 cell or 28 cell trays.

Some flowers don’t like root disturbance or root very deep. For example, taproot growing plants like Daucus carota Dara or Amii Majus or deep-rooting Lathrys (sweat peas) we start in the 40 cells deep module tray.
