Girls Gone Wild - Cannabis Flowering with Supplemental Red Lighting

guess it really just boils down to balance, and not too much or too little.

and what ones goals are.

DO NOT use Far Red for flowering weed

There is some evidence that adding some far red to the grow light spectrum will increase yield very slightly. However the corresponding reduction in cannabinoids and terpenes means a much lower quality of harvest in terms of potency and aroma.

interesting with all this R:FR talk

;p

just some more data to add, pehaps.

Very interesting, I was going to use them again at lights out after they are finished stretching but I may have to reconsider after reading that. I did it last crop for 15 min at lights out from 4 weeks -10 and I'm not seeing any decrease in potency....I still get the buzz.

My first run with the reds produced much frostier buds than normal. I'm not at all sure where Migro is getting their information from. They are usually on target but this one I dispute. I feel that the far red made a noticeable difference in the quality of my buds on my last run.

yea the research he used was this

https://www.researchgate.net/public...t_of_short_wavelength_radiation_in_a_spectrum

and this



i have not went through these papers yet, so im not sure how the test was conducted, and how they got to their results.

I added the blue to fight the stretch. My plants look pretty compact to me. Granted, every stem is also bent like the one in the picture above. lol

Edit: Here it is again so you don't have to go back a page to find it.

they look pretty nice and healthy to me, i doubt you running reds the way you are would reduce any type of metabolite synthesis.

This is where I got mine. I bought it with the red. I am pretty sure it can be purchased without the red as well.

That's why I'd like the blues, I like what the reds do but so much stretching is limiting their use. I've only used them for 1 week this run ....and my plants are under control for the first time in a long while. Since playing with the reds I think.

I guess browse around on Amazon? Maybe Ebay? I believe they make a difference with the stretch. My last run, the internodes were spaced a bit further than I liked. I still had a decent yield, but the plant structures of these girls suggest they will produce more weight. Of the 3 cultivars, I have grown Gorilla Roadkill before. It's a fairly heavy yielding plant under normal grow room lighting with both gorilla glue and skunk parentage.

I kind of already done that there's only 1 place I could find rapid led with the pucks. Same as my first reds. I may have to give them another look. Unless of course they get hit with the T word and put them out of my price range.

Here's what Claude AI had to say about the pictures. I uploaded the same ones I posted on here today.

Based on the images you've shared, I can see your plants are in early flowering stage and looking quite healthy. Here's my analysis of what I'm seeing:


Current Plant Status (Day 11 of 12/12)​


The plants are showing excellent early flowering development with:


  1. Healthy Structure: They have robust, vibrant green leaves with good coloration throughout. The plants appear to be developing a nice architecture with good spacing between nodes.
  2. Early Stretch Phase: The plants are clearly in the stretch phase that occurs during the first 2-3 weeks after flipping to 12/12. They're developing nice vertical growth while maintaining good internodal spacing.
  3. Support System: I notice you're using plant support rings/cages which is excellent foresight for when the buds develop and become heavier.
  4. Even Canopy: Your canopy appears relatively even, which suggests good light distribution and consistent growth across all plants.
  5. Light Penetration: The side lighting appears to be effectively reaching lower portions of the plants, evidenced by the healthy growth throughout the canopy.

Lighting Effects Visible​


Your sophisticated lighting setup is showing clear benefits:


  1. Color Response: There appears to be some purple/reddish hues developing in some leaves, which can be a response to the specific wavelengths you're using (particularly the blue and far-red combination).
  2. Leaf Orientation: The leaves appear to be reaching upward/outward in a healthy manner, suggesting they're responding well to the light source without showing signs of stress.
  3. Early Bud Sites: Though still early, I can see what appear to be developing bud sites at leaf junctions, which is appropriate for day 11 of flowering.

Recommendations Based on Images​


  1. Maintain Current Strategy: What you're doing appears to be working very well. The plants look extremely healthy at this stage.
  2. Monitor Stretch: The plants will likely continue stretching for another 7-14 days. Your approach of letting them grow up into the lights rather than constantly adjusting height seems appropriate based on their current development.
  3. Defoliation Consideration: As flower sites develop further, you might consider some selective defoliation of larger fan leaves that are blocking light to developing bud sites. This would typically be done around day 21-24.
  4. Support Reinforcement: As buds develop, ensure your support system remains adequate. The early implementation of supports was excellent planning.

Your plants look to be in excellent condition, and your lighting strategy appears to be working very effectively. The combination of spectral wavelengths is clearly supporting healthy development at this early flowering stage.

@Pipecarver those "T"-words are going to come out of my wallet eventually ... and groceries already have hit my pocket harder.

I have a special package arriving tomorrow that you helped me choose. Thank you for the help with that! At some point in the not too distant future, I am going to introduce tissue culture in this thread as kind of a side show to the grow.

Tell me about it...you sent me down that rabbit hole!
Our mutual friend has had my attention since yesterday lol.....I wonder if it pulls all available info and forms it's own opinions or if it tends to lean to one source more....and if so what that source might be. Guess I could just ask ole Claude as soon as I get more time allotment.

I've been having fun with it. There's also ChatGPT and Gemini (and others) that you can move to once you hit your limits. That way you aren't shut down.

I've been through some tough times and its just hunker down and hope for a break, spending stops,eat a lot more K&D & dogs get to be fine dinning. Shared a can of Creamed corn for dinner one Christmas with a pregnant wife, not because it was too expensive we were brOKE BROKE. But we survived that so what ever, I got my weed and enough seeds to last through an apoclyps .......just tough growing out in the cold......I don't know how the early settlers ever survived...it makes me shiver thinking about it.

I'm not struggling to survive. The bills are paid, and theirs always food on the table ... but I'm also still in the workforce. I pay more to live and have far less to enjoy after everything is paid for. I don't know what I'll do or even if I'll ever have the chance to fully retire at this rate.
 
@Observer - I saw your post and then it disappeared.

Yes, I am pushing the limits on nutrients. Although no, that's more the lighting that makes the greenery look that way in places. It is heavy, but its also being dialed back every week. It's only the 11th day since I changed the light cycle. Plants still need their nitrogen during flowering ... just not at the same ratio as earlier in the grow.

Didn’t you test the uv over at the other place @moe.red and found it doesn’t produce anymore trichome production.or was it something else .
Click to expand...
Yeah multiple experiments.

UVA tended to bring out colors like the purples and tended to color petioles and such. Had pics of a tiger stripe petiole where it was obvious that the shaded parts were green and the parts that got uva were purple. Anthocyanin response.

UVB was tougher on the plants. Reduced harvest weight. Could not prove or disprove more frost because of mistakes made in the setup. I put pins in the buds and took pics from the same spot over flower but the buds swallowed the pins so I lost my reference point. My gut told me there was no significant impact I just could not prove it.

UVB seemed to make the plant finish faster but was damaging.

There was a correlation with higher CBG production but not enough data to prove causation

Under uvb I got measurable THCv on white widow that never expressed it without.

All that said I decided it would take 10+ experiments to find the sweet spot of power position and timing for uvb and didn’t think it was worth it. Went to the next shiny object.

UVA seemed like it didn’t really help or hurt but again more testing would be needed to say for sure. I was only using (2) 30 watt bars in a 4x4 space lots of room to increase power there and see what happens.

Did not fuck with uvc and don’t plan to.
