Sow in spring or autumn, just covering seeds as light is required for germination. Germination in 30 days at 15–20°c Can be sown between Feb-July. Sow on the surface of the soil and gently press in, the seeds need light to germinate. Germination can take up to 90 days at 13–16°c Keeping sufficient distance between plants and a light source is especially important when using bulbs that produce a lot of heat, like incandescent and high-pressure sodium. But even with LED and fluorescent lights, maintaining a proper distance helps to ensure healthy plant growth. Sow seeds at any time covering them very thinly with compost, seeds require light to germinate. Can be direct sown. Species resents root disturbance. Germination in 30–90 days at 15–20°c

As lighting technologies have become more efficient, grow lights that only emit light from the red and blue wavelengths of the light spectrum have become more common. Incandescent bulbs are the least-expensive option, but they’re also the least energy efficient. They also have fairly high heat outputs, which is not the most ideal growing condition. Growing SeasonLightly cover the seeds. If germination is poor, cold stratify for 4 weeks. Germination in up to 30 days, at 16–18°c Sow directly where they are to flower, and lightly cover with soil. Germination takes 30–90 days at 13–16°c These benefit from predominantly blue light to promote good growth and compact plants. The T5 HO tubes should be placed around 60cm (2ft) above the seedlings for around 16 hours a day.

Red light is required for growth at the germination stage (as well as later in a plant’s life). It helps roots to grow and seeds to germinate. There are studies to suggest that blue light could actually impede germination.Two 36-inch, 6400K, full-spectrum T5 fluorescent bulbs (3,730 lumens) give optimum coverage, and the high-tech reflectors shine directly onto plants for vigorous growth with less glare. Sow in autumn, lightly covering seeds. Require a period of cold moist stratification. Germination up to one year at 10–16°c If your hydroponic lights are too intense for your tent, you can experience heat problems. If they aren’t intense enough for your tent, your overall yield will be low. Though plants can only use PAR light for growth, a broader light spectrum can really enhance growth.
