Here's a list of Canadian Suppliers that's a couple years old but should still be good. See attachment in .txt format.
At the beginning of this thread I notice that Roots and GH are recommended. I guess that's OK if you don't mind supporting companies that have denied pot growers like GH has since it's inception. It's now owned by the Scotts/Monsanto/Hawthorne/Bayer group of companies that have set their sights on the pot industry to make their next trillion dollars selling low quality products sourced in China for massive profits. GMO pot seeds won't be long in coming.
I've used AN nutes since they started up and say what you want they are good nutes made here in Canada first and now in the US as well. Their 3-part is no more expensive than the others including GH and you don't need all the fancy and overpriced supplements to grow lots of good pot. Never having to check pH is a huge bonus and something I've come to really like.
I'm also using MegaCrop nutes with good results and recently won a small 7 part kit of REMO nutes that a buddy, (who like me has been growing for decades), swears by so there are other good options out there.
I'm a fussy old fart who cares about what companies I support with my cash and am the same with food and drink that I put in my body. No junk and most of it is junk these days.
Rant over! lol
Guess I can't upload a .txt file so will try to post the text part in the next post.
For now here's a pic of the CBD girl still outside growing in the garden with her own little greenhouse. Heavy frost last night at -4C so she had a sheet over the top and front with a heater on low that kept the temp at +4C inside. There's a remote sensor hanging in the middle of the plant that I can monitor from my desk. Mainly fed MegaCrop nutes but lots of other goodies in her feed in a base of about 120L of ProMix HP with more goodies mixed in there too. Weather looks like it's going to shit here in northern Alberta so I may start cropping her soon but I'd like to limp her along for another couple weeks. Trichs are almost all milky so for a CBD plant she good to go but the buds are still full of white hairs and noticeably fattening up the last week or so as it's been warm and sunny during the days.
She's 5ft tall and was supposed to be an auto fem but grew as a regular fem and didn't start flowering until mid-August.
My first ever outdoor plant that made it to the finish line in 20 years up here. Haven't even tried for over 15 years and do all my growing inside 'til this.
The only leaves that have gone yellow so far are in the warm air path from the heater. Another reason to think she's not quite ready yet. I'm betting 4lbs wet after a light trim fresh off the plant and into the freezer for making edible meds with.
I have a vegging monster-cropped clone off her growing in the spare bedroom under T-12s with a couple different Kush varieties. Two Monkey Banana kush plants flowering down in the grow room too.
