I'm in Southern CA. I grow indoors with the temperature usually in the mid-70's.

Here's an update on my soil situation. I tried to find a mix that contained no animal manure and read about a mix called PRO-MIX Ultimate Organic Mix which is OMRI certified. It is made up of

Canadian Sphagnum Peat Moss
Sea-based Compost (from composted shrimp shells & seaweed)
Limestone (for pH adjustment)
Perlite
Mycorise® - endomycorrhizae inoculant

Sounds great but unfortunately i couldn't find it anywhere in my area.
So, i figured i would have to mix it myself. I found Premier Peat-Moss by Premier Horticulture at Lowes. At a local nursery i was able to pick up Gardner & Bloome Perlite and Dr. Earth Kelp Meal. All of these claim to be 100% natural so i'm assuming i'll be within organic standards.

Now, since i'm in a temperature controlled environment, should the Perlite make up a small amount like 10-15% of the mix?
