Dry start method- knowing when to fill?
I've done the DSM in my mini-L for just over two weeks... Using UG... My question is when do I know it's ready to be filled?
Is the purpose to spread the UG to cover the entire foreground? Or to establish good roots?
So far i have noticed new growth, and can see deep roots spreading along the front glass...
I do have press. Co2 ready to go full blast once I fill it...
I don't mind waiting, I just want to find the right balance between good growth and the least amount of melting.
