Grapefruit: Easy to Harvest Citrus Gem

Grapefruit from Positronics Seeds is a feminized cannabis strain that lives up to its name with an aromatic profile that mixes sweet, sour and citrus fruits. After 8-9 weeks of flowering, expect high yields of energizing herbs that required little to no effort!

The plants grown from this strain will have a single, long, dominant cola and very few branching. They can grow quite tall but not too wide, so outdoor growers can make great use of this strain having no vertical limit. The budding-sites will develop countless pistils that will quickly turn orange and give a nice contrasting color to the emerald green of the rest of the plant.  We advise using trichomes’ color, and not pistils’ color, to determine ripeness of the buds. This strain can yield elevated quantities after a flowering time between 55 and 60 days long. Outdoor plants will be ready by the end of September.

  • Best results in organic mediums;
  • Excellent for SOG, and Main-lining;
  • Indoor light per m²: 400-600 Watts (HID), 240-300 Watts (High Efficiency LEDs);
  • 1.0-1.4 EC during vegetation; 1.5-1.8 EC during flowering.

Uplifting Flavors

The euphoric and almost psychedelic effects of this strain are attributed to its high THC content. But its uplifting effect is also linked to its thick aromas that remind of sweet fruits that transform into citrus flavors with sour undertones. Just delightful!
