Prahas Seaweed is supplied as GRANULES in a 1.5 KG bag — the net weight is printed on the pack. The application guidance previously shown here described a liquid concentrate and was wrong for this product; it has been withdrawn rather than left standing. Correct granule rates are being finalised and will be published here when Prahas can stand behind them. Nothing is guessed in the meantime.
How often to apply depends on how much is applied, so the schedule is withheld alongside the rate. Both will be published together, from the same source, or not at all.
