a few things I observed as a store owner:
Because I was in CO....winter shipments were a bitch. I was always receiving/sending back shipments with frozen product. The first time it happened I had no clue the shit was frozen....accepted the order...stacked it in the shop....and went home.
The next AM when I arrived for the day there were multiple cases of product mixing and leaking onto the floor.
So much for the hydro guy making big bucks/livin the life of ease/always being in Tahiti. The only luck present in the entire scenario was that the store was warm. Another customer told me a tale of dropping a quart of "
Floralicious" on his concrete front porch...in January.... and the shit instantly started freezing to the step.....as did any attempt to wash it away with water. He did say that his wife's flowers that Spring were >extra< large/pretty..... but that was the only goood thing about any of it and they ended up having to come into the house through the garage for a good 3 months to keep from tracking the shit in....
If ya made it this far...something else I know is that >old< liquid chem nutes will separate/crystallize....and you will HEAR the stuff rattling in the bottle when you shake it. >Old< organic nutes will show themselves via the bottle sucking in on itself as the oxygen is eaten up from inside the mix. (still Ok for flowers/lawns.....but pot is worth too much to risk it, IMO).
Check
GROTEK nutes for formulas that...I believe...AN reverse engineered and copied/jacked the price to fuck in their line.
Definitely some very similar products in the mix
