Critical Jack Auto by Silent Seeds grown indoor and outdoor
Critical Jack auto indoor
In indoor grows, you should place around 9 to 16 plants per square meter using a SoG technique, creating a beautiful sea of green buds. If one of the plants grows taller than the others, you'll need to move it out to the corner of your grow area so it doesn’t shade the rest of your plants. They can grow up to a meter tall, but their average height is around 50cm tall.
Growing Critical Jack Auto by Silent Seeds Seeds outdoor
Outdoors it does well with plenty of sunlight and nutrient-rich soil, as it’ll practically take care of itself – you’ll need to fertilize once or twice weekly when watering, and you’ll be rewarded with 70 to 120g per plant in just 70-80 days after germination.

Seriously good stuff this. The buds came out chunky and super frosty. And the buzz? Perfect for chilling'. Really easy to grow too, barely needed anything.
