Lighting Recommendations

You will notice we have changed our light level recommendations from being in units of footcandles to micromoles per square meter per second (µmol . m -2. sec -1 ). This allows us to provide more accurate light recommendations while using the latest in light measurement technology. Footcandles are a unit of measure of how the human eye perceives light while µmol . m -2. sec -1 are the unit of measure of light plants perceive and utilize for growth. Here are some common recommendations in footcandles and the approximate equivalent in micromoles for comparison:

GROWER SUCCESS GUIDE 2024–2025

Substrate Moisture Level Management Guide For most crops, media should be allowed to dry between irrigations. Alternate between moisture level 2 and 4. Substrate Moisture Level Management Guide For most crops, media should be allowed to dry between irrigations. Alternate between moisture level 2 and 4.

Dry Substrate is tan to gray in color, crumbles to dust, pulls away from sides of container

Medium Substrate is light brown in color, no water can be extracted, and substrate crumbles

Moist Substrate is brown in color, strongly squeezing the substrate will extract drops of water

Wet Substrate is dark brown but not shiny, no free water seen at the surface, when pressed water drips easily

Saturated Substrate is dark brown to shiny, free water on surface, water drips freely from the bottom of container

ANNUALS | VEGETATIVE PROPAGATION

Angelonia angustifolia Angelonia CARITA ™ / CARITA ™ CASCADE REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME

PINCH

PROP TIME BOTTOM HEAT

105-cell (30 mm) or larger

URC, AutoStix ®

Not recommended

CapSil ® (spray adjuvant) can be sprayed on the cuttings at a rate of 2–4 oz/100 gal within 1–2 days after sticking to help rehydrate the cuttings. Misting should be significantly reduced after 2–3 days and after cuttings become fully hydrated.

Recommended 3.5–4 weeks 72–74 °F (22–23 °C)

Comments: Carita Angelonia has moderate vigor and will generally need a plant growth regulator (PGR) treatment in propagation. To control growth after rooting, sprays of B-Nine ® WSG (1,500 ppm), or a tank-mix spray of Altercel ™ (1,000 ppm) + B-Nine ® WSG (1,500 ppm) are sufficient. Do not spray Florel ® on Angelonia since this can burn foliage and cause significant flower delay. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue.

Aptenia cordifolia Dorotheanthus MEZOO ™ REC TRAY PRODUCT FORM ROOTING HORMONE MIST TIME

PINCH

PROP TIME BOTTOM HEAT

105-cell (30 mm) or larger

URC, AutoStix ®

3.5–4 weeks 70–74 °F (21–23 °C)

Comments: Sassy Argyranthemum have moderate vigor and will generally need a plant growth regulator (PGR) treatment in propagation. To control growth after rooting, A tank-mix spray of Altercel ™ (1,000 ppm) + B-Nine ® WSG (2,500 ppm) is normally sufficient. It is also becoming popular for growers to combine Florel ® at 350–500 ppm with the B-Nine ® WSG solution listed above to increase growth control and to improve branching. These Florel ® + B-Nine ® WSG combo sprays should be applied to actively growing plants. Do not spray B-Nine ® WSG or Florel ® + B-Nine ® WSG tank mixes on stressed or weak cuttings. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue.

Recommended 4.5–5 weeks 72–74 °F (22–23 °C)

Comments: Cabrio Calibrachoas are compact-medium growers and should not need the typical growth regular in propagation that other more vigorous varieties require. To keep plants under control, a spray of B-Nine ® WSG at 1,500–2,500 ppm can be applied after cuttings are well-rooted and vegetative growth begins. A tank-mix spray of Florel ® (350–500 ppm) + B-Nine ® WSG (1,500 ppm) can also be used to control growth and improve branching. These Florel ® + B-Nine ® WSG combo sprays should be applied to actively growing plants and done ideally before pinching.

Comments: Do not reduce mist too soon during propagation. Continue light misting until all cuttings are rooted into the media. Reducing mist too early can result in slow and uneven rooting across the bench. To keep plants under control, a spray of B-Nine ® WSG (2,500 ppm) or B-Nine ® WSG (2,500 ppm) + Altercel ™ (1,000 ppm) can be applied after cuttings are well-rooted and vegetative growth begins.
