Greybeard Private Label Super Green Crack Feminized Seeds

This product is currently out of stock and unavailable.



Crossing Green Crack with Super Silver Haze resulted in an impressive strain that is as potent as its well-loved parents.


Even seasoned cultivators may find tending Green Crack x Super Silver Haze Fem quite challenging. This strain needs a lot of time, attention, and space to fully mature. Moreover, it requires an excellent ventilation system with a carbon filter because it emits a sharp and pungent aroma as it matures. Nevertheless, there are just a few things to keep in mind to ensure success. The plant is sensitive to temperature changes, susceptible to wilting if the environmental conditions are not met. In addition, it is vulnerable to overfeeding. Less is more, so give it only the essentials, and use natural fertilizers as much as possible. An organic soil mix is the best growing medium as it protects the plant’s root system and gives it a much-needed dose of beneficial microorganisms. It might seem a lot to take in now, but the buds are always worth it. A single plant could equate to 500 grams (17 to 18 ounces) of huge olive nuggets dusted with ivory trichomes. Look out for sticky fingers afterwards.
On average, it takes 8 to 10 weeks for Green Crack x Super Silver Haze Fem to finish the flowering stage. Outdoors, the buds will be ready to harvest by mid-October.
One concern when growing Green Crack x Super Silver Haze Fem indoors is the space that it needs. Staying true to its Sativa genes, the plant can extend up to 120 cm (4 feet) or more. With growing cabinets out of the question, there are still some ways to control this height. Early topping in the vegetative stage encourages the plant to grow laterally. By cutting the top growth, the height can be restricted to about 60 cm (24 inches), as well as helping to maximize the efficiency of the grow lights. Pair this technique with pruning in the first few weeks of flowering. By removing excess foliage, the plant can direct its energy to more bud production. Finally, implement the Sea of Green (SOG) method to force it into flowering earlier. For optimum growth, maintain the proper temperature. Keep it between 22 and 25 degrees Celsius (72 to 77 degrees Fahrenheit) during the day and drop it by no more than 10 degrees at night. As for the lights, 600-watt HPS or LED lamps about 45 cm (18 inches) above the canopy are ideal. As proof that all the trouble is worth it, this strain will reward you with 350 to 500 grams (12 to 18 ounces) of gigantic, fluffy buds per square meter.
Green Crack x Super Silver Haze Fem’s height is not much of a disadvantage when growing in the open air. Just take note that it prefers a warm and dry climate, typical of places near the equator. Nevertheless, it is a sensitive strain, so be careful, especially with the watering and feeding schedule. Typically, the buds are ready to collect in October. There can be a bounty of 500 grams (17 to 18 ounces) per plant if all goes well.
