What is the N-P-K calendar?
To help alleviate any potential confusion around the N-P-K ratio, nutrient companies have developed feeding calendars to accompany their products. These calendars easily direct you on when to change nutrient regimes throughout a cannabis plant’s lifecycle. Importantly, calendars give you the ability to witness the N-P-K ratio changing from vegetative growth to flowering on specific dates.

Do bloom boosters work for cannabis?
Bloom boosters present a somewhat divided subject among cannabis growers. Many feel cannabis plants can only handle certain amounts of phosphorus and potassium — anything beyond that threshold is considered extraneous. Some growers swear by bloom boosters, stating they are necessary for a big harvest, while others take a more passive approach during flowering.
Is cannabis a photoperiodic plant?
Cannabis is a photoperiodic plant species. This means changes in daylight hours stimulate different growth phases in the plant. To illustrate, cannabis plants remain in vegetative growth when they have considerably longer days than nights (summertime).

What is PPM in water?
PPM, or parts per million, is a measurement of how much nutrients are present in your water or grow medium. To avoid over- or underfeeding your plants, it's a good idea to always measure the PPM of your soil or grow medium to see if it still contains nutrients.
Why do plants burn?
Nutrient burn is usually caused by overfeeding or nutrient buildup in the grow medium. Plants develop dark green leaves with almost neon green tips that bend upwards almost 90°, and deep red, magenta, or purple stems or branches.
