A descendant of two superstar strains

MacMelon auto seeds are a Watermelon and MAC auto cross. These famed ancestors are behind the strain’s savory taste and beautiful appearance.

MAC auto is the descendant of Colombian Gold, Starfighter, and Alien Cookies. It produces large, resinous buds with 14–20% THC. Experience a balanced high when consuming this strain. Mac auto may relieve symptoms of nausea, insomnia, and chronic pain.

Watermelon is an indica-dominant strain known for its relaxing, sleep-enhancing effects. It boasts the delicious taste of fresh watermelon and other sugary fruits. The strain may alleviate muscle spasms, insomnia, depression, stress, and appetite loss.

Savor a delicious fruity taste

MacMelon auto takes after its tasty and potent parents. Consumption results in an initial fruity flavor. While some perceive orange or other sugary fruits, others observe watermelon notes.

Savor an earthy finish as the fruitiness disappears over time. Enjoy the hash, skunk-like aroma as you continue to puff on the nugs. Limonene is one of the main secrets behind MacMelon’s exciting flavors.

Encounter ultimate relaxation after elation

MacMelon auto seeds grow into appealing nugs with about 20% THC. The strain takes you to a euphoric state through a powerful cerebral buzz. The potent sensation travels around your whole system.

The MacMelon strain makes you elated and optimistic. Its ability to promote happiness could reduce the risk of depression and anxiety.

After the initial buzz, the strain’s indica side gets to work. It unknots tight muscles and calms your body and mind. Expect to doze off and enjoy a peaceful night’s rest. 

MacMelon may be the perfect cultivar for relaxing after a busy day. It can elicit hunger, making it a potential choice for those with appetite loss. The cultivar reportedly relieves the symptoms of chronic stress, pain, and muscle spasms.

Top tips for cultivating MacMelon auto seeds

Although MacMelon auto seeds require some attention, they’re beginner-friendly. The plants do well indoors and outdoors if the environmental conditions are conducive. Install a greenhouse when growing in an area with unfavorable weather.

MacMelon seeds thrive in varying growing mediums. We recommend well-aerated soil mixed with coco coir, vermiculite, or perlite. It promotes root spread, aids drainage, prevents rot, and reduces irrigation frequency.

Keep the temperature in your grow tent around 68–77°F during the day. Lower it by 10% at night. Maintain humidity at 60–70% during the seedling and vegetative stages. Reduce it to about 45% when your MacMelon auto plants flower.

Install LED or HID lamps to optimize illumination for your crops. Unlike photoperiod marijuana strains, autoflowering variants don’t require a light switch. Implement an 18/6 light schedule at all growth phases. Some cultivators give their crops up to 24 hours of rays.

Adjust your light sources to ensure adequate illumination reaches your crops. While excess intensity may stress the plants, insufficient rays could weaken them. Position the lamps at least 12 inches from the topmost canopy.

Autoflowering plants thrive when they receive a balanced amount of nutrients. Supply nitrogen, phosphorus, and potassium when your MacMelon auto seeds enter the vegetative stage. Calcium, magnesium, boron, iron, and other elements also contribute to cannabis growth.

Pay attention to your watering technique and frequency. Irrigate your crops when the topmost layer of the soil is dry. Ensure the soil is always moist, but avoid overwatering it. Consider your plant size, pot size, and environmental factors before irrigation.

Monitor the water’s pH value, as it affects nutrient uptake and yields. Maintain a range between 6.0–7.0 when growing marijuana plants in soil. Keep the pH levels at 5.5–6.5 for hydroponics and other soilless mediums.

MacMelon plants usually stretch to an average height. They’re relatively easy to manage, responding promptly to low-stress training (LST). This method controls their size, increases productivity, and creates a uniform canopy.

Thes cannabis plants bloom for 8–9 weeks and yield up to 18 oz./m². Outdoor cultivators can reap their crops in October. Confirm they’re ready for harvest by checking their trichomes and pistils.
