TECH TIPS

If needed sprays of B-Nine ® WSG at 2,500–5,000 ppm or A-Rest ® at 2–4 ppm may be applied.

Soil temperatures lower than 75 °F (23 °C) during germination may decrease germination rates. Keeping media pH at 5.8 or lower will help reduce the likelihood of Thielaviopsis infections.

TECH TIPS

Usually not required if growing cool. If conditions are warmer or darker than ideal, spray with B-Nine ® WSG at 2,500–5,000 ppm.

Keep media pH below 5.8 to help avoid Thielaviopsis infections. Under hot temperatures provide lower light levels to reduce heat stress. Also, if very frequent irrigation occurs due to high temperatures, apply a supplemental feed of Solubor ® to avoid Boron deficiency.
