Water trays for Huw Richards HR20 and HR10 Seed ModuleTrays

These are simple water trays or drip trays for the the popular and practical HR20 and HR10 seed module trays designed by Huw Richards and manufactured by Container Wise.

These seed module trays have quickly become my favorites for growing vegatable seedlings ready to transfer to my no-dig raised beds in my garden.  They are so much better than the flimsy, single-use trays that I was using previously and should give at lease 10 years of service according to the seller.

However, if you do not want compost water draining onto your windowsill you will need some watertrays for the seed module trays to sit in.  These are simple water trays that I designed specifically for the HR20 and HR10 seed module trays that are sturdy enough to carry the weight of filled seed module trays as you carry between locations.

I have found that these trays can warp in the heat of the sun if printed in PLA.  So I recommend printing with PETG or ABS which have both worked well for me.

This is Huw's YouTube video introducing the HR20 and HR10 trays:
