Cannabis sativa is a remarkable plant containing many valuable natural components. It has been cultivated throughout the world and history for use as a food, fuel source, nutritional supplement, body care product, source of paper, building material, medicine, and in textiles (Small and Marcus, 2002).
Cannabis sativa is a ANNUAL growing to 2.5 m (8ft) by 0.8 m (2ft 7in).
It is hardy to zone (UK) 9. It is in flower in July. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). and is pollinated by Wind. The plant is not self-fertile.
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acid and very alkaline soils.
It cannot grow in the shade. It prefers moist soil.
Environment & Nutrients
Sativa plants generally respond well to high levels of light and don’t mind a little heat, but can easily get stressed by cold temperatures
Can be nutrient-sensitive, especially in dry heat, low light levels or if a plant does not have many leaves. Not uncommon to see nutrient burn or Nitrogen toxicity at standard-strength nutrient levels.
It’s a good idea to give lower levels of Nitrogen if you see an N toxicity, this will help encourage as much bud growth as possible. You don’t want to give zero Nitrogen, but be on the lookout for dark green leaves and curled tips!
Example of buds on a Sativa plant that is suffering from a Nitrogen Toxicity (too much Nitrogen) in the flowering stage. Nitrogen “tells” the plant to focus on vegetative growth, and the plant keeps putting out more and more sugar leaves if given too much N in the flowering stage. These leaves will turn dark, bend, and eventually turn yellow again as the toxicity goes on.
