Culture guide

Usage

Packs, Pots, Hanging baskets, Mixed Containers and landscape

Sowing method

1 pellet per plug

Germination

Optimum conditions for seedling development, beginning on the day of sowing until radicle emergence. Expect radicle emergence in 3-5 days.

Media

Begin by watering to saturated (5); applying enough water to help dissolve the pellets. After sowing do not allow the pellets to dry back before moving to the germination chamber or benches. Maintain saturation (5) for 3-4 days or until radicle emergence. On day 5 reduce media moisture to wet (4) for the next 5-6 days. On day 10 reduce the moisture further to medium (2). Alternate between wet (4) and a medium (2) between watering.

Temperature

Plug Culture: 72-76 °F (22-24 °C) until radicle emergence and then reduce to 68-70 °F (20-21 °C). The temperature can be lowered on approximately day 5. Once cotyledons have fully expanded lower the temperature further to 65-68 °F (18-20 °C). Growing On: After transplant, maintain temperatures> 55 °F (13 °C) nights for the first 3-4 weeks to initiate flower bud development. The night temperatures can be lowered further to 50 °F (10 °C) to encourage basal branching and compactness. However, lower temperatures may also substantially decrease the number of flowers initiated. Growing at cooler temperatures will produce a higher quality plant. An ADT (average daily temperature of 67 °F (19 °C) will give the fastest finished crop.

Fertilization

Maintain an EC < 1.0. Fertilized water should not exceed an EC of 0.5. Upon initial germination, approximately day 5-6 begin feeding with 50 ppm nitrogen. Pay attention to the addition of boron since low boron can cause tip abortion. Ideal boron concentration is 0.5 ppm.
