haha! no i got it at a garage sale if you look at the top you can see the price of a 1.00, i originally got for my outside gardens, but never used it and stashed it away only to come across it this morning, hence the question.
do really think it would kill it though? i might expriment a little with one of my plants.
Actually, I've come across that stuff pretty often while researching for DIY nutrient recipes! It's probably not that familiar to the "premixed" - "store bought" crowd, but it's a fairly standard item at any horticulture supply store.
i mean everything in moderation? If its super concentrated just use less i guess. thats like buying concentrated juice and not diluting it with water. its cost effective at $1 though.
yeah that stuff strikes me as brutal for some reason. Maybe they need a smiling old lady on the cover in a garden hat... Lemme know how that stuff works, you might end up with some behemoths
