You know, Canna, there really isn't much info out there on this strain. The breeder info only says that it is a dwarf variety, calls it "compact" and also suggests it is good for sog. Flowering is supposed to be 45-55 days. It's pretty fast. It is a cup winner from Amsterdam in 2000 or 2001.
I'm sure how tall it gets depends on the amount of time it veges. Roxy had an extra week of veg and is about 6" taller than Dyarina. Both plants are probably about done stretching. It'll be interesting to see how it fills out in flower.
It's sort of interesting to contemplate how well it would do with a three week veg in one or two gallon pots. In a space like yours you could probably run two deep and five across - ten plants. It would harvest in around 80 days assuming a three week veg, nine days after 12/12 to start flowering, and a 55 day flower period.
My White Panther is three weeks ahead of yours, and I'd have to agree that it could easily be a sub-90 day strain. It set pistils right on schedule at about 8 days into 12/12. I've finished a couple strains in under 90 days and they both yielded over 2 zips. If I like the produce from the WP I think I may try it on a 60 day veg/60 day flower perpetual cycle - that's really convenient for clones. A 90 day grow makes it hard to keep a strain from clones - kinda need mothers to keep up the schedule.
