Do I have to use Rockwool to germinate my seeds?

[atb]

I just bought a DWC and I was wondering do I really have to use rockwool to germinate my seeds? can't I just put the seed in the hydroton or is there any other way to do it cause im an idiot and forgot to buy rockwool and the closest store that sells it here is in toronto....

You do not have to use rockwool and I would not.
You can just use the hydroton rocks if ya want.
Or you can use other things like rapid rooters or pellets or what ever else ya want.

loads of ways to germinate seeds. ive germed right out of expanded clay. looked kind of funny but worked fine.

About how far down in the hydroton

I fill the net cups up about 1/2 to 3/4 of the way full with the hydroton, place germinated seed on top with the tap root going down. Let it do it's thing and get anchored. Then just fill up the rest of the net cup with hydroton as it grows upwards.
