rootit cubes goin dry help

I put my seeds in rootit cubes witch were soaked before hand in a heated propagator how can i stop them dryin out and how.long wil they take to germanate and can i use my mh bulb for them

You don't need the heat. Just let the water soak in at room temp and they will start the germination process. Like Sub keeps saying these are outdoor plants they are designed to germinate and thrive by themselves in nature. Good luck

Just let them germ at room temp. Heating them will only cause them too dry out fast and can promote a higher number of males

and read more about how to grow in rooters, plenty of info here
