G13 strain, also known as Government Indica Strain 1, is a beautiful Indica-dominant hybrid with a mysterious origin and a legendary reputation. According to numerous urban legends, G13 strain was a creation of the US government in the early 1970s. However, it is very hard to prove this notion because weed was illegal then, making it impossible for breeders to track down the specific genetics. The G13 strain is a testament to the creativity and innovation of cannabis breeders and growers, who have transformed a ‘secret experiment’ into a legendary cannabis strain.

G13 strain, also known as Government Indica Strain 1, is a beautiful Indica-dominant hybrid with a mysterious origin and a legendary reputation. According to numerous urban legends, G13 strain was a creation of the US government in the early 1970s. However, it is very hard to prove this notion because weed was illegal then, making it impossible for breeders to track down the specific genetics. The G13 strain is a testament to the creativity and innovation of cannabis breeders and growers, who have transformed a ‘secret experiment’ into a legendary cannabis strain.
The G13 strain seeds’ genetics journey is a fascinating story that reflects the history and evolution of cannabis culture. The G13 strain was allegedly leaked to the public by a scientist named Neville Schoenmakers, who worked at the University of Mississippi, where the government’s cannabis research was conducted. He reportedly took some cuttings of the G13 strain and distributed them to various breeders and growers in the underground cannabis community.
Germinating cannabis seeds activates the dormant embryo inside the seed, stimulating it to sprout a root and a stem. There are several methods to germinate weed seeds, but one of the most common and simple ones is the paper towel method. Here are the nine steps to germinate G13 seeds using the paper towel method:
Feminized seeds are better than regular seeds for some cannabis growers, depending on their goals and preferences. Here are some of the reasons why feminized seeds are preferred by many:
G13 strain seeds can develop up to 6 feet tall indoors and 10 feet outdoors, depending on the growing conditions.
Indoors, G13 strain seeds grow into stout and bushy plants, flowering in about 8-10 weeks.
Here are some of the pros of growing G13 seeds indoors:
The following are some drawbacks indoor growers can encounter when cultivating G13 strain seeds:
The G13 plant is usually harvested late, anywhere between late October and mid-November.
The benefits of cultivating G13 seeds outdoors include:
Some of the disadvantages of growing G13 cannabis seeds outdoors are:
You can choose a soil media to enhance the flavor profile or grow the G13 strain in hydro for rapid growth.
Outdoors, G13 weed plants thrive in warm, dry Mediterranean-like climates found in California, Australia, and Southern Europe. Indoors, keep the growth conditions dry and the temperature between 64 and 84°F.
G13 is a dense and bushy strain that can be vulnerable to mold or rot if insufficient air circulation exists in the growing area. You should also avoid overwatering your G13 plants or letting them sit in stagnant water, as this can create a favorable environment for fungal growth.
The G13 strain is simple to grow and a great alternative for growers of all experience levels. These cannabis plants are resilient, versatile and produce abundant harvests.
Its easy-to-grow nature and disease resistance make the G13 strain an excellent choice for novice growers, promising a successful harvest.
G13 is a high-yielding strain that produces up to 21 oz per square meter indoors and up to 40 ounces per plant outdoors.
Consider using the Screen of Green setup, SCROG, pruning, and LST to maximize space and increase yields.
You can use the following training technique to boost the yields of your G13 plants:
LST stands for low-stress training, a technique of gently bending and tying down the branches and stems of cannabis plants to change their shape and expose more bud sites to light. This can increase the yield and quality of the buds and control the plants' height and size. Furthermore, LST is a simple and effective way to improve your cannabis yield and quality without causing too much stress or damage to your G13 plants. It can also help you fit your plants into your grow space and optimize light usage.
SCROG stands for "Screen of Green." This training method involves bending and weaving branches outward through a trellis net or customized "SCROG screen" to regulate the canopy. SCROGGING is most effective when the plant has been topped or fimmed and has several side branches. These two training approaches complement each other perfectly! The sooner you can start SCROGGING and teaching your plant, the better. The SCROG technique may require more vegetative development time to get the ideal structure, but the potential yield boost alone is worth the wait!
SOG stands for sea of green, a technique of growing cannabis that involves cultivating many small plants in a limited space. The objective is to create a canopy of buds that maximizes the light exposure and the yield. SOG is ideal for indoor growers who want to harvest quickly and efficiently. Furthermore, SOG is a simple and effective method to produce G13 cannabis indoors with limited space and time. It can also help you save money and resources by reducing the need for equipment and maintenance.
The G13 strain is not just beautiful, but it’s also lush and vibrant. Its earthy green nugs contrast beautifully with the light blue trichomes and amber hairs, creating a visually stunning plant. The G13 strain is truly a sight to behold, with its vibrant colors and lush growth!
