This has a very high success rate. All the
seeds can sometimes germinate and in most cases
often do. The disadvantage to this method is
that you need to spend money on the tray,
rockwool and grow fertilizers. The price of the
tray is about $10/£10, the rockwool cubes
$5/£5, the grow fertilizers $5/£5. If you have
spent $50/£50 on seeds then why not spend the
extra $20/£20 on getting a small kit together
like this. The other advantage is that you can
use this same tray to help root your clones.
