Good question... I get confused reading all of the stuff on the internet. Broad explainations sometimes just dont do the trick and thats why we (or at least I) join helpful sites like this.
The statement I found in the general FAQ section said:
"Indica plants are short, bushy, mature early, have more chlorophyll and less accessory pigments (accessory pigments protect the plant from excessive sunlight). As Indica strains have more chlorophyll than sativa they grow and mature faster.
Sativa plants are taller, take longer to mature, have less chlorophyll and more accessory pigments (accessory pigments protect the plant from excessive sunlight). As Sativa strains have less chlorophyll than Indica they take longer to grow, mature, and require more light.
Hybrid plants have a combination of both Indica and Sativa growth characteristics which are relative to strain ratio."
The last sentence made me question the statement from Dutch Passion regarding the Flo I am currently starting which states:
"Original Flo is a Sativa / Indica cross with very Sativa phenotypic characteristics that also matures very early. The large, tight, spear-shaped buds are made up of small, densely packed purple calyxes. The plants are taller and like to branch out. Indoors the buds are fully mature by the end of their sixth week. Flo is ideal for greenhouse production. The motivational high produced by Flo is quite unique."
Now I'm no expert, but 6 week flowering time seems very short for any plant to be mature. By reading the last sentence in the general FAQ I would make the assumption that the flowering time would be somewhere between 8-12ish weeks.
I guess maybe characteristics aren't always relative to strain ratio.
