Welcome to my Pink Rozay Diary.
Sorry about the missing weeks. But lost my pics.. was only about another 10cm of growth she put put on in her 2 extra weeks of veg and got the past 7 days she's been flipped and has started her go on the new UV/IR45.
Total she got 5 weeks of veg and is currently flipping.
Haven't had much in the way of trouble with this lady. Showed she K shortages half way into the flip this week. So adjusted the feed and she quickly came about. (Added some PK booster from Green House Feeding)
So, I've read up about how to use far red to make my plant go to sleep quicker. (As you need 10 hrs of darkness to sex a plant and it takes 2hrs or so for it to go to sleep, so by using far red 730nm before and after the plants lights comes on you get a 26hr day if that makes sense, how you ask. Cause far red used at the right time can change that time of 2hrs to 5mins to put your plant to sleep. So In turn you get them 2hrs that it should of took to put your girl to sleep, you can now use them 2hrs to keep your females under longer, so you use them 2hrs to give your females extra photosynthesis. It's all got to do with pfr and switching to pr quicker, 'Phytochrome'.
Thanks to my sponsors from Original Sensible Seeds & Mars Hydro for supplying me with great seeds and lights and for their continued support. And shout out to all who visited, liked or commented much appreciated guys. Look forward to checking out your grows.
Hi guys. So has anyone got experience using far red 730nm to switching pfr to pr (photochrome)??
I'm looking for any general knowledge, tips and experience using. Also when can I push my fems to a 14-10 cycle, do they have to be out of pre flower before I can push it to that?
An expensive spectroradiometer is not needed to achieve this this. Apogee has cheaper ePAR meters that can detect the 730nm wavelength now. I just got one and will be measuring the ratio in my light bar very soon.
It comes down the to the ratio of Red photons to Far-Red photons(R:FR). This ratio matters much more than just the intensity of the far-red light alone. Normal daytime R:FR is 1.3:1 (1.3%) and is applied throughout veg. Sunrise and Sunset have an increase R:FR at about 0.6 (0.6%) for about 30 minutes each.
“The R:FR ratio of direct sunlight is about 1.3 during most of the day, but it approaches 0.6 or so during twilight when the atmosphere preferentially
scatters blue light and the sky turns yellow and red. This only lasts for half an hour or less, but it is important because plants use these changes to
synchronize their internal circadian clocks both with the 24-hour day and the seasons. This involves a burst of gene expression activity that is
controlled by phytochrome.”
“High-pressure sodium (HPS) lamps, on the other hand, have an R:FR ratio of about 4.8, metal halide lamps have R:FR ratios varying from 2.6 to 3.4
and white light LEDs (regardless of color temperature) have R:FR ratios varying from 3.6 to 4.0. Various fluorescent lamps have R:FR ratios varying
from 5.5 to 13.0 and above.”

The University of Utah Crop Physiology Lab uses a R:FR that is lower than normal daytime ratios (1.5:1 or 1.5%) to minimize the effects of stem elongation in their experiments. Below is an example from one about phosphorus overfeeding vs harvest yields:
“The fraction of far-red photons (700 to 750 nm) was 1.5%. Because the far-red fraction was low, the classic PPFD and the ePPFD were within 1.5%
of each other”

This actually explains how you use far red to change the photochrone time and it gives you extra time to to have your plant under the light. Its proven. Anyways. Thanks for your reply

@FrontRowAG_BrianG, Ah, that was from grower error pal. I used Far Red 730nm during pre flower with the lights on. "Tricks the plant into thinking its been shaded out, and causes stretching"
As she's indica Dom. She should me m be at least 1/3 smaller..
