Welcome to my Original Sensible Seed test grows.
This strain is Pink Rozay. 30% THC 70% indica 30% sativa.
Pink Rozay feminised seeds from Original Sensible Seeds are an indica dominant cannabis strain with a deep sensual relaxing effect. A genetic infusion of Cherry Pie x London Pound Cake the plants of Pink Rozay grow bushy and stout developing lavish dense buds with orangy hairs which develop purple hues toward the end of the flowering period generously glazed with sparkling THC trichomes.
Will be using PT as my germination method.
Will be put into 11L pot to start for veg and them moved into 18L pots for flowering.
Lights used Will be my new SP 3000 + UV/IR45.
Shout out to both my sponsors from MarsHydro + original sensible seeds, (reps). Who have given me these products to test for them. Much appreciated guys!!
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..
