Maria Shields –
Easy to develop since it is resistant to pes and molds. It needs to be trimmed every now and then. it’s great long-lasting relief and hour-lasting euphoria, with the smell of earthy and musky, is just perfect for the sweet and sour taste. I highly recommend this as an anti-depressant and for body pain.
K. Snyder –
my plant grows outdoor, 8 weeks time she blooms gives a high yields. i harvested around 800-900gr/plant,sooo happy!.i have arthritis,at night i have troubles in sleeping,this eases the pain and relax my body tends me to fall asleep. when i started using this,my everyday life changes to more productive and calm. moreover,it is resilient to molds and diseases makes her easyto cultivate. northern critical produce generous yields when cultivated outdoor in warm dry climate..don’t forget her earthy zesty scent ,when smoke lingers the tongue,a fruity sour taste with spice is pleasing!.more seeds soon..

An amazing strain that produces a massive yields for about 500-550 g/m2, it has a dense buds.. Grown this indoor and used LED light also I watered it just 2x a day. The flowering time was about 6-8 weeks. It has a loamy scent of earth with a spicy sweet and sour taste. I had this insomnia before but when using it, it really helped me, I started sleeping tight at night!

This strain was not a very strong growing seed but was able to harvest it after 60 days! I cultivated it outdoor and grew up to 60 cm tall with its yield of 500 gr per plant, I started using it because I had a depression that causes my anxiety, stress and I really like the effect. Apart from its pine and skunky taste as well as it scents I was able to manage my emotions and felt like HIGH everytime I uses it so it was great!

Very effective! Super love the woody spicy herbs scent as it taste! Smoke was light and high! Been depressed but after using this light smoke, it felt like heaven! Grown this strain indoor with a flowering time of 8-9 weeks and it was 40-60 cm tall, has a dense buds.. It wasn’t an easy cultivation coz I needed to trim the leaves everytime it grows, not suited for beginners but moreover, it was fun and good!
