What Kelp/Seaweed extract are you using in Canada?

FWIW, for about the first decade, I purchased pallets of 10L jugs (they come 2/box, which is probably why there's a 20L minimum), repackaged and sold the stuff as KelpMax.

The one potential flaw with buying in bulk and repackaging is that, unless your containers and work area are reasonably sterile, the shelf life is drastically reduced.

I’ve been using Strathcona 1890’s Plant Tonic on my houseplants for a few years. Haven’t thought to try it on my orchids recently though.
