That plant couldn't be more bushy and the bud structures have a lot of leaves coming out of them, both point to indica. Is there a sativa strain that grows bushy and leafy that I'm not aware of?
It is clear that you have limited experience. It is also clear that you do not understand the difference between something being sativa and it being predominantly sativa. Sativa means pure sativa, no indica in the strain at all. Predominantly sativa means 51% or higher in sativa and 49% or lower in indica and plants with that sort of percentages of sativa and indica can still appear to be mostly indica.
You said; " Is there a sativa strain that grows bushy and leafy that I'm not aware of?" Evidently there is, or at least in something predominantly sativa if not pure sativa.
Rumors and guesses on the parentage of Romulan abound. Claims that the Romulan is a pure Indica (Afgani/Kush) are mistaken. While there may be some genetics from Indica (Afgani) varieties, anyone who has tried true Romulan knows that the mind warping effect is that of plant with strong sativa traits.
According to `Romulan Joe,` 'keeper of the flame,' the original breeders started growing in there backyard and greenhouse in the 50`s, after being introduced to cannabis in the Korean war and bringing home seeds to Victoria. They struggled to grow and acclimatise these seeds
selecting the faster flowering shorter plants from the tall lanky Korean strain.
When the late sixties, early seventies rolled around they began trying Colombian and Mexican seeds and hybridized varieties from these. In the mid 80`s when the Afgani strains swept into North America they briefly tried hybridizing with these but eventually when back to selecting the traits they liked in there old genetics.
They worked mainly with Sativa genetics but always selected shorter squatter phenotypes which has made many people think that it is a purely Indica strain.
Having 38 years of growing experience I have complete confidence in saying that the strain in the pictures in this thread is predominantly sativa, just as I originally stated. I would not attempt to guess a percentage amount, or even a half-narrow percentage range. Depending on which phenotype was chosen as 'the strain' found in a cross looks can be deceiving. But when you add the rest, like having flowered for so long and the trichome color still being clear/cloudy, that tells you there is a goodly amount of sativa in the strain. If the strain was a heavy indica it should have finished well before now and if allowed to grow until now the trichomes would be brown, not amber .... brown ... and all the plant would be good for would be compost.
