Graffiti® Falls

Flowering Type: Day neutral plant, will flower regardless of day length. Providing a 14-16 hours day length, especially in the seedling stages, and growing at warmer temperatures will shorten the crop time significantly.

Flowering Mechanism: Higher irradiance and warmer temperatures will promote earlier flowering.

Germination: Maintain optimal conditions for seedling development beginning on the day of sowing until radical emergence. Expect radical emergence in 7-10 days.

Cover: No cover.

Sowing method: 1 pellet per plug.

Media: pH 6.2-6.5, EC < 0.5. Starting with the proper pH of the media will improve the performance of the seedlings. If the pH is too high, a micro nutrient deficiency may occur and if too low, an iron toxicity can occur.

Temperature: 23-26 °C (74-78 °F). Once germination is completed, the temperature can be lowered to 22 °C (72 °F). Water trays using tempered water with a minimum of 18 °C (64 °F). Media temperatures below 16 °C (60 °F) will inhibit the growth.

Moisture: Begin with a saturated (5) for the first 10 days. Then, begin to lower the moisture slightly going to a medium (4). Maintain a consistent moisture level without over saturating the media.

Humidity: Ensure high humidity of 95-100 % until day 10, then reduce to 40-60 %. Provide proper ventilation and horizontal airflow to improve oxygen levels in the media.

Light: Light is not crucial for germination but providing supplemental lighting will increase the quality of the seedlings and uniformity of germination. If using a chamber provide a light source of 10-25 ft. candles (100-250 lx). Later in, the light levels can be increased up to 3,000- 3,500 ft. candles (30,000-35,000 lx).

Fertilizer: Maintain an EC < 0.75. At this stage fertilized water should not exceed an EC of 0.5. Begin feeding on day 10 with 50 ppm nitrogen.

Plug Bulking and Flower Initiation: Optimum conditions during the vegetative stage from cotyledon expansion to flower initiation.

Media: pH 6.2-6.5, EC 0.75-1.2.

Temperature: As plants become more mature, the temperature can be lowered to 18-20 °C (64-68 °F) nights and 22-23 °C (72-73 °F) days.

Moisture: Alternate between a wet (4) and a medium (2). 

Fertilizer: Maintain the EC level below 1.2. Under lower light conditions fertilize with a calcium based fertilizer (14-4-14) at 100 ppm. Under higher light use a 17-5-17 feed at 100 ppm.

Fungicides: Under conditions of low light and high humidity fungicide applications may be necessary

Media: pH 6.2-6.5, EC 1.0-1.2.

Light: Provide high light levels of 3,500-4,500 ft. candles (35,000-45,000 lx). Long day treatment of 14-16 hours will shorten the total crop time significantly.

Temperature: 20-21 °C (68-70 °F) nights, 22-23 °C (72-73 °F) days after transplanting until the roots reach the bottom of the container. Thereafter temperatures may be lowered to 16- 18 °C ( 60-64 °F) nights and 20-23 °C (68-74 °F) days.

Moisture: Alternate between moisture levels wet (4) and medium (2).

Humidity: 40-60 % humidity is ideal. Providing good ventilation and horizontal airflow will help lower the humidity and dry back the media, providing oxygen to the roots.

Fertilizer: Under low light conditions fertilize with a 14-4-14 fertilizer at 100-150 ppm and under high light conditions use a 17-5-17 fertilizer at 100-150 ppm. Watch for calcium and magnesium deficiencies which can cause stunted plants.

Growth Regulators: These genetics do not require applications of growth regulators or pinching treatments.

Fungicides: Apply fungicides during long periods of low light and high humidity.

Common Diseases: Botrytis, Rhizoctonia and Pythium.

Pests: Primarily Aphids, Thrips and Whitefly.
