Strain FAQ

Why do Sativa-dominant strains flower slower than Indicas?

Sativa-dominant strains flower slower than their indica cousins, usually in around 60–90 days. Their sluggish pace reflects their equatorial heritage, where longer growing seasons have moulded their growth patterns.

What are the benefits of medium flowering time strains?

The genetic variety of this flowering spectrum offers hybrids that combine the finest of Sativa and Indica features. These hybrids can reportedly both energise and relax, deoending on their genetic makeup, meaning there is something for everyone here!

Has cannabis potency altered over time?

Cannabis, a decade ago, reportedly used to have less than 10% THC across the board. Modern breeding methods have quickly resulted in boosted potency with legal breeders striving to accommodate the desire for stronger and stronger cannabis strains. Where strains with 10% to 19% THC were once the strongest, we are now almost getting into 30% and beyond!

What makes legal indoor growing systems water-efficient?

Hydroponics and aeroponics make legal indoor cannabis growth water-efficient. These systems recycle water and nutrients, reducing waste and use. This win-win is said to provide plants with critical nutrients while minimising environmental effects.

Why do some cannabis strains smell like citrus?

Cannabis strains with citrus flavours and fragrances contain terpenes. These chemical compounds give many plants, including cannabis, their distinct flavours and fragrances.
