Read on to learn how to give seeds the right environment to germinate and grow.
There are a few simple tricks you can incorporate into your seed starting process that will help you increase your success rate and avoid seed starting disappointments.
How quickly they do so is often dependent upon whether you’re giving them the optimal conditions.

Place the sprouted seed on top of your growing medium and cover with dry seedling mix. Mist with your spray bottle and place under your growing lights.
