How's she looking? Another week or so?
Ignore the naysayers. I just chopped several plants smaller than that one. It was my first time growing 12/12 from seed (and the last time).
Looks good HerbGardner.....I had planted a stunted, solocupped Gorilla Glue auto outside....probably 4 inches or so.....tiny.....
Come harvest, it produced maybe two grams.....couple bowls....that's it.....
Wow......don't underestimate these plants....
Not knowing anything about the grow, it definitely looks like at least 2 more weeks, by the picture of the bottom pistils/stigmas being totally white. Please don't go by just the bottom of the plant...I'm just s
If the plant is in your yard, just put on an outdoor light for a few hours a night. A flashlight sounds like it could be a pain.Lol thanks for the positivity everyone, this poor girl's had a hard life. Growing 12:12 is ridiculous but it was the fastest way to actually seeing my own bud, a bit of inspiration for actual growing season.
Legalization means weed is cheap and plentiful so I'm just growing for experience. I feel like I'm growing tomatoes at home but still buy from the store.
For next time, if I just shine a flashlight on my plant for a few hours a night, would that be enough to keep her in veg or would I need something brighter?
They require hours of continuous darkness to start flowering, so it shouldn't be too hard to disrupt, right?
when the plant get around 12 hour night time it trigger the release of florigen hormone wich induce floweringIf the plant is in your yard, just put on an outdoor light for a few hours a night. A flashlight sounds like it could be a pain.
"If this dark period is interrupted even with a brief exposure of red light (660-665 nm wavelength), the short day plant will not flowering ."
I found this from Ed Rosenthal, he says I can use a flashlight so long as it covers the whole plant, but we do live in the 21st century. He just has a yard light on a timer shining for one minute intervals throughout the night.If the plant is in your yard, just put on an outdoor light for a few hours a night.

Thanks for the info, I'll need a second to digest it but basically Pr tells the plant it's getting enough sun whereas Pfr tells the plant to grow onto a better position, right?so as mysticepipedon said any "warm white" spectrum kind of light will interrupt flowering if used accordingly but even 15-30 min should be enough

"Phytochrome is a pigment that is found within the leaves of all plants, as well as cannabis. The role of this pigment is to detect light to then allow the plant to grow accordingly based on the season or time to induce flower production. When light hits the surface of a leaf, there will be two types of light sensors at work: one which has the job of detecting blue light and one for detecting red light.
Phytochrome In Cannabis – Pr
The Pr represents the light absorption at a peak of 666 nm, whilst Pfr represents the light absorption from the range of 705 – 740 nm. When Pr absorbs red light, it will then be converted to Pfr.
Technically this wavelength of light is classed as red light, and during this time, red light changes phytochrome to its biologically active form. Plants that are dark green and usually with short internodal spaces are an expression of Pr range being utilized.
Phytochrome In Cannabis – Pfr
The ‘fr’ stands for far red, and this determines wavelengths or red light that are not Pr but form in the range of 705 – 740 nm, which absorbs at a peak of 730 nm. In the same way that Pr is converted to Pfr, the same occurs when Pfr absorbs far red light and is then converted back to the Pr form.
It sounds complicated and what the relevance of each one does can be hard to understand, however the Pfr phytochrome is responsible for inducing flowering as it corresponds to the amount of available light or shading that is present. There is a role for phytochrome in controlling gene expression, and these can cover the factors of stem elongation, stomatal function and light sensitivity in terms of floral production and plant metabolism."
you need to give a signifiant amount (enough ppfd over the whole plant i guess) for it to work, for exemple moon do produce a little amount of blue light at night but it' doesn't trigger flowering
"If this dark period is interrupted even with a brief exposure of red light (660-665 nm wavelength), the short day plant will not flowering ."
So seedlings that haven't been exposed to light (and etiolated plants) are full of Phytochrome A. This gets converted to Phytochome B in response to light, telling the plant to turn green. There's also Phytochome C, D & E but that's beyond me right now.it's a bit more complicated both convert to each other, the thing is that' thoose red light receptors pf and pfr that trigger flowering when enough uninterrupted night time
