My experience with Berry Bomb from Bomb Seeds:
5 Fem seeds purchased, 5 for 5 germ rate and very fast, 5 for 5 flowered and finished female. I took cuttings of each for sexing and future grow purposes.
As stated previously, very stretchy and spindly. Due to height and long veg restrictions I also top alot which may contribute. The overall yield for me matched other strains. The buds were smaller and less dense, however I had significantly better growth to lower nodes unlike other strains I do which led to overall similar yields.
Distict lemony smell in 2 of 5 plants, very appealing. I did end up with some small amount of purpling of leaves on 1 of 5 with out specifically regulating temps for it, however this one plant is also going hermie at approx 6 weeks. It's damn near ready to harvest, so I'm gonna have to give it closer inspection to see how bad it is, though it's got alot of male clusters in the immature lower growth, hopefully not adversly affecting the rest of my room.
Fastest flower I've dealt with. Shows flowering, and colored pistols 1-1.5 weeks faster than my clockwork 8 week strain. Could probably be cut as early as 6 weeks, though 7-8 for indica effect, which is delicious and potent.
Possible mite vulnerability. Not sure why, since mine are not particularly dense, though leafier than others. I have 12 plants, and 2 Blueberry Bombs in the room have significant population, while my other plants show no signs.
