How to Grow Critical x GG4 Autoflower?

Critical x GG4 Autoflower seeds can be grown indoors or outdoors under optimal conditions. The plants are compact, robust and moderately easy to grow, though it is always worth guarding against pests. A few methods help retain and enhance the terpenes and flavors of your buds:

• Use a quality substrate. Perlite, peat or coco coir are ideal for moisture retention.
• In our customers’ experience, good technique can increase yields by up to 20%.

As an autoflowering strain, Critical x GG4 Auto switches to flowering on its own, without a change in the light schedule, so it is forgiving for newer growers. It will grow under as few as 12 hours of light, but we recommend an 18/6 or 20/4 cycle for the best High yields. See our full grow guide for more detail. Feed quality nutrients through the seedling, vegetative and flowering stages, and indoors set up good tents, fabric pots, LED lighting, an air extractor and a carbon filter. Keep daytime temperatures between 68 and 80 ℉, and night temperatures 7 to 9 ℉ cooler than the day.

These plants prefer low humidity: 55 to 60% in the vegetative phase, around 40% in flowering, and down to 30% by harvest.

Outdoors in the northern hemisphere, sow in April for a first harvest in mid-summer and a second between July and mid-October, at about 12.35 to 15.87 oz per plant (350 to 450 g). Indoors, the cycle runs 8 to 10 weeks with yields of 1.47 to 1.8 oz/ft² (450 to 550 g/m²).

Ideal Climate for Growing

Critical x GG4 Auto flourishes in a temperate climate of long, sunny days and mild nights. The optimal temperature range is 70 to 80 ℉ (21 to 27 ℃), which promotes robust growth and enhances the terpene profile for a more flavorful yield. Adequate sunlight and protection from extreme weather further support a successful harvest.

In the United States, ideal states include California, Oregon, Nevada, Arizona and Florida, which provide the blend of sunlight and warmth this strain needs. Texas, Georgia and North Carolina also offer suitable climates, provided care is taken to avoid excessive humidity and heavy rain. With the right environment and steady temperatures, growers can maximize the potential of Critical x GG4 Auto for bountiful, high-quality harvests.
