I know what you are saying - there truly isn't a legitimate WB grow journal from start to finish (at least not that I've been able to find while doing searches). I wish I had a camera.
I have one WB flowering right now, it will be harvested in about 4~9 days. As far as yield (produce) goes, it really depends on how large you grow the plant. Cloned plants have the reputation of delivering better yields than plants grown from seed, so that is something to keep in mind. I expect to get about an ounce from the one plant, the main cola is like a 2 liter bottle!
I started flowering mine at around 6" from seed and it ended up being about 18" after a consistent stretch throughout the first three weeks of flower. Showed sex within three weeks of inducing flower under a 400w HPS. And it is most definitely main cola dominant...you'll see. From my experience, thus far, the plant's growth pattern has been consistent with the breeder's description and limited reviews/forum journals. I am growing Cheese beside the WB and it definitely has more trichome development than the Cheese. I would say the WB has a more floral smell rather than "berry" aroma, although that's to be expected since the plant's heritage is apparently not from Blueberry genetics. No CO2, Advanced Nutrients Sensi 2-part with several additives: beneficial fungi, bacteria and and an additional liquid suspension of 5 'superstrain' bacteria, enzymes, B-vitamins, carbohydrates and a 3-part flowering nutrient progression - Bud Blood (P-K), Big Bud(AAs & P-K), Overdrive (AAs & Vit. C).
I started flushing a few days ago, so I'll keep you updated on the harvest, drying, curing and smoke details.
Nine plants is too many for that lamp, and 2-liter bottles won't allow you to grow very large plants, the bare minimum is usually 10 litres/plant. How large did you plan on letting these ladies grow?
