Pistils under blue vs. red LED lighting.

So in my current grow, under an SG602 VEG and also an SG602 Bloom,
they are both placed side by side, length wise so they intersect but still have three different sections of lighting,
one pure blue, one blue and red, and one pure red.

Now, They are at week 4, aproaching the end of,

and the buds under the blue lighting only have no red hairs what soever,
on the same plant the buds under the blue and red have a bit of red hairs at the tip of the white pistils,

and the plants under the red lighting only are full of red hairs more than 35% of the length of the pistils.

Now if the red hairs are a way of determining when your plant should be harvested,

I think i could definately manipulate this to harvest buds for an extra amount of time to ripen while still keeping the red hairs to a minimum by using blue lighting for a longer period and then switching to red when i want to ripen at the end of harvest.

My theory is that this will happen to the thc as well and i will be able to prolong the thc from going amber.

However another effect is the leaves on the plants under the red light have more thc on the leaves close to buds.

I'm just curious as to why this would be, but i guess a more controlled experiment would be necessary to pin point what the case is,
and even if my observations are correct.


I don't know,
What do you think?

I agree with this completely. From what I have done with par t5. Too much 420 nm blue during flower slows flowering. Too much 630nm and/or 660nm red during veg will slow down growth.

In flower with too much blue, it does make them take longer to finish. But buds are smaller. So you do.want more red than blue during flower.

Look what I posted in another thread.

ΔΔΔ I was just thinking the T5 crowd had definitively proved by manipulating spectrum you can change the behavoir of plants. What I've observed so far with adding Far Red LEDs to my grow is proving to me that LED panels are like golf clubs. They work best in certain situations. I used to scoff at veg panels. No more. Now I'm thinking LED growers should have at least 2 flowering panels, an early flowering and a finishing panel for later. That's why I really like the idea of small modular groups of lights that can be swapped in and out of one's panels.

Thats the best idea.. For example if the apollos came with extra modules that you could swap instead of flipping a switch. Still be using all diodes. They would be plug and play. When I order my next apollo. Im going to talk to the sales rep about that.

That is a good idea, but the lights i have all say the warrantee is void if this seal is broken, but since i got these through customs they already broke it for me lol!!! yay customs, so i basicly bought this light without a warrantee.

but yes, maybe they could just slide in and out like card readers on your computer!!!!!
just push them in, then push them again and they will pop out, slide it out, and put the other ones in.

just give me a good box to store and preserve my modules and i will feel really special.

Great thread man.

Since adding my new apollo 6 in my flowering tent which has 240bs and 500bs flowering models, growth has changed, seems the same plants are more stretchy. My conclusion is with the custom flowering spectrum of the apollo which is 3000k,5000k,6000k,10000k and 12000k with 3x630nm and 7x660nm with all that extra white/blue light the transition into flowering is about 10-15 days longer than when i had the 2 blackstars.

In the pics the LST trained bush is mostly under the 500bs with only the inner middle colas towards the inner part of the tent are receiving white light, the single cola tall plant in pic1 is mostly under the white light, except the lower cola's which are receiving most light from the 240bs. Pic6 is the same pheno as plant in pic1 but it was grown under 500bs and 240bs, was chopped at day 50, the single cola pic is only day 35, it seems the pistil development is different, i've also noticed under the white light trich prod starts at the same time but frosts up alot faster, but then again, I might be improving my techniques along way and this can contribute to this, only time will tell.

Peace to all and happy growing.

Added 2 new pics, both clones from the same mum, one was grown with just the bs240 and bs500, both had same pot size and medium, only difference is pic1 plant had the ap6 panel added about 5 days into flowering, its now day 38 on a day 55-60 strain. I've also added 2 new organic nute additives to my nute regime, they might be playing a role in nutrient uptake etc, but the growth rate, size evident over the plant just grown with 430watts of LED oposed to 600watts of led with added white spectrum (3k,5k,6.5k,10k,12k LEDS), Also raised the panels from 7 inches to 15 inches and the plants still stretched teh same as oposed to 430watts at 7 inches.

FranJan opened a thread about how blue can effect growth due to specific hormones being present due to the extra targeted blue spectrum, im sure higher ratio of blue is detrimental to growth rate when it comes to flowering, its seems logical to replace most blues with whites and having only a very small ratio of blue.

Happy growing, peace to all and stay safe.
