DO NOT START SEEDS IN OCEAN FOREST!
Ocean forest is heavily fertilized and this is a sure-fire way to burn your seedlings...don't do it unless you want your 4th grow to be your 1st.
For SEEDS you want something that contains virtually no fertilizer. You can start them in straight coco-coir, or use something like Black Gold seedling mix or Sunshine Organics mix. Seedlings don't need to be fed, not from liquid or dry ferts and not from the soil- for at least a couple weeks. If ANYTHING you could mix in a MINUTE AMOUNT of worm castings, which will provide some extra nitrogen, calcium, magnesium and beneficial microbes. I def. wouldn't plant them in 5-gal buckets either. The problem with this is you'll be wasting a hell of a lot of water, which the plant wont be taking up because it has no roots...could result in early damping off, before the seed even emerges. You just need a container at least 4 inches deep to give the tap-root plenty of room. I use and recommend the red (or whatever color) beer cups.
My latest batch I used Black Gold, Coir and a small amount of worm castings. No real fertigation for two weeks, and the result:
