looking for kelp sample

[Ray]

Either one will work, but I recommend straight KelpMax without fertilizer for transplants.

Solo is really only intended for the casual grower with only a few plants, who wants a simple method of providing nutrition with a little "kick" of hormones to help spark root growth. If your pretreatment is more concentrated to get a bigger "kick", then the mineral content and EC could be excessive. Don't forget that the Solo product is to be used no more than every two weeks (for the auxin/cytokinin hormone cycle to mostly complete itself), so has a stronger dose of fertilizer than one might use if feeding more frequently.
