35 days today for my 4. Your girl looks great!! I was advised not to top her? Looks like a fimming did her very well? I was thinking another month on mine, but I know I'm wrong now!! Very nice.
Thanks BB! I never topped her because I had read not to top autos (but I see that
AFnOOb got away with it in his very successful grow). You can see how she turned into a little bush when I bent her over 90 degrees (using so-called "no-technique" training) so she'd fit in my little fireplace grow room. (She still outgrew it when she went into stretch, though.)
More than anything I ended up having to constantly defoliate her--her foliage would get so dense that I was worried she couldn't breathe--no air circulation. That's all over now though. Five weeks after preflowers first appeared on April 12 (which was 23 days from seed), and after explosive growth in the month-long flowering stretch, she's now just sitting there building her buds (and drinking half a gallon of water a day from her hydroponic reservoir).
I nipped away many many leaves, little growth shoots, and budlets ("lollipopping" I guess) to keep her focused on her buds. (BTW, I'm practicing my curing technique on the nipped budlets and they still have a way to go, but even though they taste kind of harsh and grassy when I vape them in my Sub-Herb dry vaporizer, they are pretty potent! She started getting quite sticky by day 45--about 3 weeks into flowering--and there is a lot of resin not just on the flowers but the surrounding leaves.)
CropKing says "six week flowering time" for DLF, and I'm now into that sixth week since the first preflowers appeared, so time is running out, but the biggest buds are still only a couple of inches long and not as dense as I'd like, but after the tough time I put her through in her early life (drowning her in too-wet rock wool in week #2), I think she has popped back and done really well.
Next time I will be super careful during all-too-brief and cannot-be extended vegetative stage of an auto to make sure the plant gets off to a flying start instead of having to recover from my mistakes and catch up. I will also provide more light (just adding more and more CFLs and LED bulbs has gotten kind of comical, but they do have the advantage of allowing you to put light where you want it). Hydroponics has required lot of work mixing and measuring, and I have made some mistakes (trying to adjust the pH too often), but when you get it dialed in, it sure works!)
Anyway, time to go tend to her ladyship (measure her tank volume and top-off with nutrient mix, adjust the lights, take her daily portrait).
Good luck with your grow and keep us posted!
