In my most recent purchase from mars hydro, I also...

Using UV, IR, and deep red lights can improve your grow, but the impact may vary:. UV Light: Encourages resin and terpene production, improving aroma, flavor, and potency. The effect on yield is subtle but can enhance bud quality. IR Light: Helps with light penetration, promoting deeper growth and potentially increasing flower size. The improvement in yield is subtle but can lead to more even growth. Deep Red Light: Most effective during flowering, it stimulates bud production and increases overall yield. This will likely give the most noticeable improvement in your grow. Conclusion: Using these lights on their recommended cycle should improve the quality and yield of your plants, especially if you focus on deep red during flowering. The effects may be subtle, but with careful use, you should see better buds and possibly a higher yield.

type-o that needs fixing last paragraph "...effect on the amount of branching seed," seed = seen

probably not. confirmation bias, small samples, genetic diversity make this impossible to assess with your eyes. The science behind uv creating a something positive from the damage it causes is not confidently provent, yet. It may or may not improve areal density of trichomes. Important to use them properly too... depending on intensity you run for a short period of time each day and only in flower phase when trichomes are developing, otherwise it's a total waste and use in vege will only allow the plant to grow resistance to the uv and then their effect is zero. This is why testing with field craps showed no benefit - the exposure to uv from early stages of life meant the plant built up resistance to the effect of uv. Indoor testing has been less conclusive in that regard and not confident it helps, either. This is more trustworthy than someone with no education/experience backround looking at something with their eyes... simply not something the human perceptions and context of home grows can resolve unless you lie to yourself about it. i've never bothered, so i can't give any suggestions as to how long or exactly when in flower to apply the UV. Even if you do find specific instructions, it's based on whimsy at best at this point as there is no reputable answer on this, as of yet. UV diodes die much, much faster than your typical lm301 diodes, so it is pertinent to longevity not to use them all day long all grow long. Within a couple years of constant use they will be 80-90% as productive and dimming much faster over time at that point too. ~10,000 hours on longevity curve typically is "L90." and that assumes they are not over-powered compared to original manufacturer's spec sheet (not the grow light maker) Far red: I'd use the far red the entire time. I regularly use half 3400k and half 2900k and the effects, while measurable, are irrelevantly different, lol. So if you ened a fe w more umol/s of light to hit a target DLI, then keep the far reds going all the time. I have a personal preference to warmer CCT grow lights, but again.. not something any 1 individual can resolve given the varity of genetics and small sample sizes in a home garden... and i grow 10-12 at at time. you won't see a huge jump in yield unless it is the cause of adding a good chunk of DLI and you were giving too little before. DLI = yield, not quality. Genetics = quality. Can't put lipstick on a pig no matter how hard someone tries. i don't like cooler white even in early vege. I have always liked the growth pattern under my 2900K lights more so than my other lights with higher CCT (more blue). My diy 2900K lights are far superior in growth rates to my xs1500 -- i use it simply because it's 150w and saves a bit of power, but it definitely seems to take looger before i can do my first transplant than in the past when i used the 2900K for that stage of life. It's bugging me so much lately, i might stop using the XS1500 altoegether. Way too high CCT. I don't notice a huge difference in outcomes comparing the 2900k to 3300k lights. (can't recall if 3394 or 3294K, lol.. but same difference) My grow platform is 1/2 each. It may have a statistally signficant effect on the amount of branching seed, but remember this does not mean it is a large efect.. it's actually a very small effect that is never going to change a lanky or bushy plant into the opposite of what it's genetics dictate.

Yes you will i have used these before and i am currently using them to date, i have noticed increase in quality and also 15% in yield

I don't think you will. its just sprinkles on the icing on the cupcake. But I could be wrong.

No you wont, unless you go for a very heavy HST and use them as sidelights or underlights, and even then for the Cost you pay on power it will maximum increase yield by 10-15%. Also the reds are not for the full cycle of the plant be careful. I would not use them unless you go for Plants as a "show off".

Only use the deep red light bars during late flower don’t use the up and it lights there is tons of info out now showing they don’t help your plants
