As i had a surplus of seed trays, having switched to multi-cell tray inserts i decided to investigate the possibility of converting some of these to gravel trays. From all of the seed trays i found two types that were suitable to be converted. I experimented with a hot glue gun to seal the holes in the trays allowing them to be used as gravel/watering trays.
I have been developing an automatic watering system for my greenhouse for a number of years for seedlings and small plants. It uses a commercially available micro-irrigation system to deliver water to the seedlings. I grow seedlings in multi-cell tray inserts as i have found over the years it protects the roots compared to separating plants when they are ready to be planted in the garden or pots. I put the multi cell trays into gravel trays which hold water which can be soaked up by the compost and or plant roots. Over the years i was able to buy gravel trays for approximately GBP0.75 each but these were only available for a short period each year. It was possible to also buy these from a major DIY chain in the UK but at the much more expensive price if GBP2.0 each.
