How wet is your mix Dazed? You should be able to squeeze one or two drops from a handful of soil.
You'll be fine adding to your existing mix. The only problem with adding more amendments to a mix that has already started to cook is that you have to let it go that much longer. Since you just mixed this it's not going to add much more time. You want that seaweed in your mix. It's really good stuff.
The guy at the store said he swore by it, he used to collect seaweed of the beach. Thanks for the advice, I'm going to add some and the perlite in now.
Thanks to everyone who advised me on this, super excited to get going!
Much Karma to you all, hope I can do you all proud! lol,
Dazed..
