Easy-to-grow , indica-dominant plant with high yields and good resin production.
Critical Lemon is a feminised, indica-dominant hybrid strain bred by crossing Critical with Citral. Critical Lemon is easy to grow, produces high yields and plenty of resin.
Suitable for all growing environments, Critical Lemon is a fast-flowering strain, taking between 50 - 55 days indoors. In this environment yields are between 500 - 600gr/m2. Outdoors, in the northern hemisphere, harvest time will be in the first 10 days of October. The buds are packed with trichomes and have a high calyx to leaf ratio making trimming a straightforward task. A good strain from which to make extracts.
The aroma and flavour is very citrussy, reminiscent of lemon and grapefruit. THC levels are high at 19% giving a poerful indica effect.
