I used this product earlier in the year as a booster for some transplanted shrubs and other bits and pieces, with very intriguing results. Siapton is an apparently organic liquid fertilizer, with the usual mixture of NPK and micronutrients, plus aminoacids which, according to the Swiss agriculture specialist who originally put me on to it, "really activates" the plant's growth systems. Well, it certainly did that; all the transplants (mostly subtropical shrubs e.g. plumbago, Cestrum, Clerodendrum ugandense etc, plus some rose bushes) put oodles of new growth on in the weeks following treatment.
The interesting side-effect was that scores of seeds germinated in the ground - unfortunately, the majority of them were seeds from the old lawn, which I had weedkilled and ploughed out! Nothing an afternoon's pulling didn't solve, but could have done without it. On the other hand, the wee petunia, the daturas and various other surprises were very welcome. Here, a couple of photos of what turned up - from top to bottom, a white datura; dianthus that I put in as a cutting on the offchance and was rewarded with a burst of flower; the "re-seeded" grass!, the dear petunia, and a plumbago which was 3 inch tall bare twigs in April.
I would be interested to know if anyone else has had similar experience with this product and whether in fact it can be used as a germination aid (not something it is advertised for, on the bottle at least!)
