Pinching and Growth Regulators
Soft Pinch when the plant is 3 to 4 inches tall. The lower the plant breaks the better the plant quality. If flowering is desired, allow 10 to 12 weeks after the onset of long days for flowering. 'Shockwave' is grown for foliage as much as flowers and may have a shorter crop time since flowers are unnecessary for sales.
