Watering Modular Trays
Q: Watering modular trays
I have been sowing some of the veggies you recommended for this time of year under protection in your book. Just wondering how often to water the modules trays they are on a heating mat.
If you have the trays on a heating mat you will have to water more regularly. Keep in mind that they always need to be moist – never too wet and never too dry. So often and light watering is essential.
On a sunny day you may have to water twice and otherwise once. Only water if they need it – when you’ll see the surface of the compost drying out. On other days it will need to be checked and possibly watered once. It’s quite difficult to get a watering can with a very fine rose on it, otherwise it’s too easy to over water the seedlings.
