How to grow cannabis with LED grow lights to supplement the light?

Cannabis cultivation: How to grow cannabis with LED grow lights to supplement light? The growth and development of hemp requires an effective accumulated temperature of 2400-3200°C. The seedlings can tolerate frost at -5–3℃, and the low temperature will not affect it for a short time

Hemp seedlings grow. Cannabis is more planted in early spring than when the soil temperature is above 8℃ at 5 cm below the ground surface. After 30 days of emergence of hemp seedlings, most of them do not irrigate, and use LED grow lights to promote their growth to control seedlings and promote roots. 

According to the difference in the morphology of female and male seedlings, male seedlings can be selected to remove female seedlings when setting seedlings to improve fiber quality. The female seedlings are selected for the hemp field. The suitable temperature for hemp growth is 19-23℃. The average growth of hemp plants is 3-5 cm per day, and can reach about 10 cm at the peak of growth. 

At this time, it can tolerate atmospheric drought but not soil drought, so continuous irrigation is usually started one month after emergence to keep the maximum water holding capacity of the soil at about 80%. Combining irrigation with early application and reapplication of quick-acting fertilizers can promote stem growth. The seedling density varies with local cultivation methods. Generally, early-maturing varieties retain 80-150 thousand seedlings per mu, and late-maturing varieties 3-5 thousand.
