Not available in Canada sadly
No one carries it anymore and companies that are listed on the botanical website said it's not available anymore.This says Canada is cool with it. http://news.agropages.com/News/NewsDetail---14654.htm
This man knows wtf he is talking about. 100$ will gets enough tea to treat probably 2,000 gallons of res water. Use the method for maintaining if you aren't fighting slime (1 cup each rez change). I use Emerald Harvest CalMag now in my rez because it has kelp extract that feed the bennies and its cheaper then most other big brands without kelp. Then add a enzyme and some aminos and you never have to use a sweetener again!If you're trying to stretch a buck, have you seen this post yet? https://www.rollitup.org/t/dwc-root-slime-cure-aka-how-to-breed-beneficial-microbes.361430/
It's a long post, but Heisenberg tea is great, I started using it after I had an issue in my current dwc, but I'm going to be using it all the time from now on.
If you can get your hands on earthworm castings, I def recommend it. Aquashield is basically hydroguard, but great white can substitute for it.
Where did you get Great White for $46 CAD? Was is on amazon.ca for 1 ounce? (https://www.amazon.ca/Plant-Success-Revolution-PRPSGW01-1-Ounce/dp/B00A8PG6RI/ref=sr_1_4?keywords=great+white&qid=1589832861&s=lawn-garden&sr=1-4)Thanks for all the replies guys. I did some research and found that the product 'Great white' does the job and actually has more ingredients but less of hydroguard's main ingredient. The price isn't that bad at 46$ CAD with shipping.
I've checked out the Southern Ag Fungicide but from my understanding it only has 1 strain of Bacillus bacteria where as Great White has many strains as well as endo and ecto mycorrhizae. Canada seems to have nuked to beneficial bacteria market!I ordered Southern Ag Garden Friendly Biological Fungicide from ebay, delivered to Montreal 2 weeks ago.
Its also like 1/20th the cost and just as effective for most people. Its the same strain as hydroguard which people have used successfully for years.I've checked out the Southern Ag Fungicide but from my understanding it only has 1 strain of Bacillus bacteria where as Great White has many strains as well as endo and ecto mycorrhizae.
