Cannabis strains by grow difficulty
Difficulty is the single most predictive variable for first-grow success. Every strain in the library is rated easy, moderate, or hard based on documented attention requirements — water tolerance, nutrient sensitivity, pest pressure, and how forgiving the cut is when a light schedule slips.

Purpose
Educational reference. Not legal, medical, or growing advice.
Easy
Forgiving across the most common grower mistakes. Recommended for first cycles and tent grows where attention is limited.
Open listModerate
Within reach for growers on a second or third cycle. Wider stretch and tighter nutrient requirements than easy strains.
Open listHard
Above-average attention required. Documented sensitivities to environment, feeding, or pest pressure.

The four signals we read
A strain's rating is the worst of these four ratings. A cut can be otherwise tolerant but a single severe sensitivity bumps it up the scale.
04
01
Water tolerance
Forgives over- and under-watering, root-zone swings, and irregular feed cycles.
02
Nutrient sensitivity
Width of the EC window. Hard cuts burn fast at the high end and stripe at the low.
03
Pest & mold resistance
Documented resistance to powdery mildew, bud rot, spider mites, and thrips.
04
Environment forgiveness
Temperature swings, light-schedule slips, humidity excursions. Tents punish the strict.
Phenotype variation inside a single seed pack can shift one plant up or down a level — select your keepers for the traits you actually want to grow long term.
