I paid $180 plus tax and handling for a 5kg tub. I say $200 because that's close enough to my total outlay, perhaps $10 more.
Photo attached. That's a quart bottle of CaliMagic sitting on top of the tub.
I'm reluctant to provide a closeup of the label because of the meta-data contained in it (I'm not in a legal state). But the potency statement quoted from the label in my post above is verbatim.
I make up each batch roughly 5 to 10 minutes before use and I make sure to make up enough for that watering event only. Certainly, I found that allowing it to sit around for more than 18-24 hours would lead to residue/sludge issues, but once it is in the coco/perlite it ceases to act that way, even if it's an older batch.
I've been using freshly prepared batches on a daily basis for roughly a month now and I have encountered no buildup problems, no sludge, no slime or scale etc etc. Everything is clean (I use zyme at all times). I was using daily for 2 months before changing my methods and I've seen no ill effects on my plants.
I've just pulled some Peak Seeds Skunk Berry and Kush Northern Lights males. They've been watered with BTi daily for 30 days and the root system on them is perfectly healthy and normal. I tried to take a picture to illustrate that but my camera isn't up to the job.
Anyway, I am sure you can track the product down. I'd be shocked if agricultural chemical companies in Southern US don't carry it, there are a lot of mosquitoes down that way.
Peace
nothing im ever worried about doesnt seem to be an issue roots exploding still. I use stickies top layers and stuff like sm-90,h202, and azamax in the res to keep em at bay. there's always a handful flying around. They come in my readygro I concluded. I just deal with em.
