15 cell Long-Life, Strong Propagation Module Tray from Containerwise.

The 15 cell module tray made from strong, durable, and recycled plastic is perfect to grow your tomatoes or other larger plants until you can plant them outside. We like to use the 15 cell tray as a replacement for all the separated P9 flower pots.

If you are growing tomatoes, peppers, or watermelons this could be the right tray for you. Because of the big cell size (almost a 9cm pot), you don’t need to transplant before you transplant your plants outside.
Module trays are a great way to extend your growing season and grow more in less space. By starting out your seedlings indoors or undercover you can save months of growing time outside. This especially helps with a short growing season or to grow more in less space.

All Containerwise trays are made out of recycled hard plastic to ensure a long life of about 15 years. Due to the use of sturdy material the trays are easy to hold with just one hand. These trays will not break or bend when used as intended. The material is UV treated to prevent degradation due to sun exposure.

What can you start in these trays?
– Larger vegetables like tomatoes or melons or any other plants you normally would grow or buy in 9 cm (P9) flower pots.

These are the first trays I own. I am very new to gardening and did a lot of research about different trays and systems. These were the best ones by a long run.
The trays aren’t flimsy and will probably last me a lifetime.


Perfect, finally

These modules are brilliant – rugged, durable and easy to use. This size is perfect for bringing on tomatoes, aubergines, chillies and French beans to the point of planting out. I’ve tried all the sizes and found the larger ones best. The Dowding modules I’m least keen on – I never sow 60 of the same plants at the same time. If they were half or one third size I’d find them much more useful. The bigger modules are good for potting on seeds sown in pots or seed trays and I have been using them non stop since I bought them in May. Will be getting more for next year!
