Critical Kush: the speed of Critical and the spicy character of OG Kush in a balanced hybrid
Critical Kush by Black Elephant Genetics brings together two heavyweight names: Critical, the strain of Afghan and Skunk roots famous in Europe for how much it produces in so little time, and OG Kush, the Californian benchmark for earthy, spicy aromas. The result is a 50% indica / 50% sativa hybrid with a restrained indoor stature, finishing its flowering in 50 days and filling the grow space with a spicy, earthy profile shot through with notes of lemon and fruit.
Why choose Critical Kush
✓ Feminized: no males in the grow, every plant reaches flowering as a productive female.
✓ 50% indica / 50% sativa: a true balance that translates into a vigorous yet easy-to-handle plant.
✓ Just 50 days of flowering: a short cycle that lets you harvest sooner and run back-to-back indoor grows.
✓ Up to 550 g/m² indoors: from plants of 90-110 cm, and up to 600 g/plant in the open air.
✓ Flavour with character: spicy and earthy, with a touch of lemon and ripe fruit.
Indoor cultivation
Indoors it stays at 90-110 cm, a comfortable height for grow tents and rooms with little vertical space. It forms a clear main stem and several strong side branches; early topping or a few LST sessions turn it into a wide, flat plant with several tips at the same height, and a SCROG net helps carry the final weight. With 50 days of flowering it yields up to 550 g/m². We recommend a spongy, well-draining substrate, watering at a pH of 6.0-6.5 in soil, light defoliation halfway through flowering to open up the centre of the plant and an activated carbon filter from the first weeks of bloom, as the Kush heritage shows in the smell right away.
Outdoor cultivation
In the open air it changes scale: it reaches 200-250 cm and can produce up to 600 g per plant when grown in deep ground or a large container with rich, airy soil. The harvest comes in late September or early October, which in many areas lets it finish before the heavy autumn rains. Look for a spot with direct sun for most of the day and shelter from the wind, stake the side branches once they start to fill out and keep the base of the plant clear so air can circulate.
Aroma and flavour
The first impression is spicy and earthy, with the damp soil, wood and spice background that identifies the Kush family. Brush a stem or open a flower and the livelier side appears: a bright lemon joined by ripe fruit notes that add sweetness. With drying and curing the whole settles down and the citrus remains as a clean finish over the spicy base.

Get the most from your harvest
A flowering period of only 50 days leaves little room to correct deficiencies: Critical Kush needs a steady, balanced supply from rooting through to the final bulking. Pair it with the Madame Grow fertilizer kits, covering growth, flowering and flower bulking, formulated in our laboratory in Andalusia.
Frequently asked questions
Is it suitable for small spaces?
Yes. Indoors it stays at 90-110 cm and responds well to topping and LST, so it fits 80x80 or 100x100 cm tents without giving up yield, which can reach up to 550 g/m².
When is it harvested outdoors?
It ripens between late September and early October. By then it is worth having the branches staked and keeping an eye on humidity, because its flowers gain a lot of weight in the final weeks.
How should I store them until sowing?
In a cool, dry and dark place, ideally in the fridge inside an airtight container. This preserves their germination power for a long time.
