can someone look at the pics on my PC? no flowers ...

More of a sativa base to the strain hence longer flower period but she'll get there 😉 looking good aside from the mould but there's not a whole lot you can do about that other then what you already are 👍

The "Durban" are known to be quick flowering sativas so nothing strange to see them going into flower soon. The pineaples strains are more like classic "skunk" so they could be ready later due to the sativa Genetic inside.

I wouldn't do anything she is in pre flower. It's genetics. Got to be patient. Some strains flower faster than others. So just get a light proof tarp big enough for to completely cover your greenhouse and when 12 hours of sunlight reaches. Just put tarp over stake down. And keep it on just till it's completely dark then remove tarp. This will help her flower quicker and u only have to do this till your hours reach 12/12 or less light. Don't want to stress her moving around. Not only can u use tarp for this grow. Your next ones u can mimic 12/12 when u want as long as it's completely dark in greenhouse. And pull 3 to 4 grows outdoors instead of one a year.

Some strains will start flowering with as much as 14h of light, others won't until they get really close to 12h of light. Not much you can do about that other than somehow blocking the light from hitting them for a little longer each night. Also, are there any strong lights nearby at all? Some plants don't mind a little indirect light when flowering and others are really sensitive and hate all but the faintest indirect lighting when it is supposed to be dark. If they weren't in the ground I would have suggested moving the PC into a dark shed/room a little before sundown every day to give it less light. It should start flowering soon though.
