Flowering plants height increase

Hey, Guys. I was wondering if flowering cannabis tend to get taller as they bud? I have a bubbleberry, GDP and Blue Dream. While the first two are flowering pretty heavily and staying the same height (from the looks of things), the Blue Dream is only just starting to flower and seems to be getting taller by the day. Is this just because the BD is a more sativa influenced plant and flowers later thus grows taller for longer?

Also, does anyone know if the buds will be getting more dense, and fill out a bit more, as they get closer to harvest? There is a lot of resin right now, but the buds seem to be smaller than what I would have thought.

All of these plants are grown under the sun, in transparent plastic grow tents (pictured below). Thanks

Bubbleberry 58" / Lower Shot of Bud Sites / Top14" (Cola)


Blue Dream 62"-Not fully flowering yet

im truly happy u did ur research
sadly im not sure of this myself but im pretty sure it should grow slower like u said
but they look like there ok im sure all u need is a matter of time

also yes they should get plenty big
youre plant budd should grow just like the plant would no worries

All plants will keep getting bigger during flowering (especially the first couple of weeks) and Sativas do tend to get a lot taller than strains that are more indica based. As far as buds, if the plant is healthy and getting the right amount of nutrients/water, then the biggest limiting factor on the size of the buds is going to be how much light the plant is getting. The more light, the bigger the buds. If you feel the buds aren't big enough, you could invest in some cheap lights to help supplement their growth.
