10 Best Strains To Grow In New Brunswick (Our Picks)

1. Maui Waui

Maui Waui loves the heat and moisture, so at first glance, growing it in New Brunswick might seem crazy.

But get this - New Brunswick actually gets pretty hot and humid during the summer, which gives Maui Waui a taste of its Hawaiian homeland. The plants go off and thrive in those conditions!

You gotta keep 'em inside once it gets cold though, or they'll get stressed. Set up some lamps and fans to keep things warm and breezy. Maui Waui is super chill - even beginner growers can handle it with no problem.

This strain's substantial yield adds to its appeal, promising an abundant harvest for growers in New Brunswick.

2. Jack Herer


The weather may not be Mediterranean sunny in New Brunswick, but Jack Herer can thrive in cool, wet conditions with some greenhouse love.

These babies can swell up massive with the right care, so be sure to stake those branches well to avoid snapping. She's a hungry girl too, so feed her right with a balanced diet and she'll reward you with phat yields.

Good news for the low-key growers - Jack doesn't reek much till you chop and cure those nuggets. So you can fly under the radar while she flowers.

You can check out our Autoflower version of Jack Herer for a faster and stealthier grow.

3. Trainwreck


If mold and mildew harsh your grow, then Trainwreck is the choice for New Brunswick. She laughs off humidity so indoor growers can relax.

Now her sativa side means she needs room to stretch. But with potential yields of 400-500g per square meter inside, she's worth clearing space for.

New Brunswick's summer temps are perfect for Trainwreck too, she thrives in 18-30°C. Just keep in mind she can hit 125-155cm tall inside and even taller outside. You may need to prune her if height is an issue.

The solid news is this girl flowers fast, only 8-9 weeks. So you won't be waiting forever for the goods.

4. Chemdawg


This hardy strain thrives in the cooler temps that New Brunswick has.

The real key is that Chemdawg loves chilling out when the nighttime comes around. So she's a perfect match for the climate here. Just keep an eye out for mold and mildew. Humidity can be this girl's downfall if you aren't on top of it.

Put in the work though, and you'll be rewarded with some seriously danky dense nugs. We're talking easy yields of 600g per plant if you get the conditions just right.

5. Bubba Kush


Bubba Kush thrives in the shifting temps of the region. She'll soak up those warm summer days and keep on trucking when it cools down in fall.

And with her short squat stature, topping out around 70-120cm inside or 180cm outside, she'll fit perfectly into any garden or grow setup you have. Her bushy shape and tight nodes are perfect for dealing with the unpredictable weather around here too.

The best part is Bubba's has built-in protection against the usual diseases and bugs that bug growers in this area. It's those resilient genetics!

If fast harvests and low profiles are your goals, our autoflowering Bubba Kush is for you.

6. Granddaddy Purple


This vibrant purple strain loves the humidity in the region, thriving at around 50% like it's her hometown.

The best part is Granddaddy Purple resists mold like a champ, so you don't have to stress too hard. And her compact size makes her perfect for indoor or outdoor setups all over New Brunswick.

With her bushy shape and tight node spacing, GDP soaks up sunlight even when it's limited. Just make sure she's got good airflow and ventilation.

If you grow her outside, she can hit 180cm and deliver monster yields of 400-600g per plant! But even inside, GDP stays short at 60-100cm and can still give you a killer 500g per m2. 

If you need big yields rapidly and stealthily, go with our Granddaddy Puple Autoflower.

7. Critical 

Critical is great for growing in New Brunswick. The short flowering time of 8-9 weeks is perfect for the shorter Canadian seasons.

And she stays so compact, not even reaching a full meter tall. That's ideal for keeping things low-key with indoor growing over the harsh winters here.

But when those sunny summer days hit, take Critical outside and she'll explode! Just watch the humidity levels and airflow so you avoid rot and fungi. Do it right and you'll be blown away by the yields though.

We're talking 600g per m2 indoors or a whopping 1300g per plant outdoors!

Our autoflowering version of Critical is ultra discreet and ready to harvest in no time.

8. Amnesia

This strain prefers warm weather despite the Afghani heritage. But Amnesia is also super resilient and can still thrive in New Brunswick's climate with the right setup.

Since the humidity and cold temps can lead to bud rot or mold, I'd say go with an indoor or greenhouse grow. That'll keep things dialed in perfectly. And with the awesome yields Amnesia can kick out, the extra effort will pay off big time!

If you're growing outdoors, just remember this girl can shoot up over 210 cm tall when she's happy! 

Check our Amnesia Auto for fast turnarounds and maximum discretion.

9. OG Kush


OG Kush is super versatile and can thrive in this region's variable climate, especially when it's warm.

The best part is she's resistant to most diseases so OG Kush is pretty easygoing overall. Indoors is ideal, and running hydro will max out her yields and potency!

One thing though, she gets pretty stinky when those buds start flowering. So if you're growing outside, plan for some odor control so the neighbors don't get suspicious.

You also gotta keep an eye out for mildew and mites. But put in the work and OG Kush will deliver with huge yields - we're talking 550g per plant outside or 425-550g per m2 inside.

Grow OG Kush faster and stealthier with our Autoflower version.

10. Purple Kush


This hardy strain can handle New Brunswick's changing weather because it resists mold like a champ.

Now Purple Kush likes it hot and dry ideally, but it's shown it can take some cold too. So she's down to party in New Brunswick! This girl also loves soaking up the sunlight when summer hits. Just keep the humidity on the low side if growing outside.

For indoor growing, the compact size is perfect, only reaching 60-80cm tall. That helps maximize your space for sure.
