Mixing 6500K and 2700K during each phase. Mistake?

Added UV definitely does increase resin production.

Look into some reptile lights(UV-B to be more prosise ), they produce UV-B which is very useful to plant life! its the only UV rays plants absorb and is suppose to cause higher THC production within your plants just by using the extra light for a few hours a day! look it up on google, it will relink you to here about UV-B

well i added a 6500k to the grow box... so I will see whassss uppppp.... lol

I flower with an 8 bulb t5 unit. I use 4 red bulbs, two Florosuns, and two blue bulbs. I got 4 1/2 oz wet from two Mars OG plants, and there's still the smaller popcorn buds on the plant that weren't ripe yet. Maybe another 1 to 1 1/2 oz still to harvest.

As compared to my first harvest with only 4 red t5 bulbs, this was substantially better.

I can't say it was ALL the bulbs though, as I changed nutes, frequency of nutes, and amount of light all in the same change.

All I know is I re-enacted the scene from Harold and Kumar with the threesome of Kumar, the girl, and the fat sack of weed.

you can see one is blue(white) the other is red(orange) which is the different times of the sun whether its morning and afternoon or June or September.. that is just what i've heard and read i'm not saying you are replicating it.. that would be impossible... ..... but as you can see from my pic.. 2700k's work pretty darn good for me during flowering. that is at 30 days and looks like its at about 50.

  • For Vegetation you will want to use 6500K or 5000K, and when you flower you will want to switch to 2700K or 3000K . The reason being, throughout the year the plant’s outside receive more 6500K light because the day’s in summer are long and hot and as Autumn/Winter get’s closer the day get’s shorter, and gradually receives less 6500K light and more 2700K light as the plant flower’s. Do what you can to avoid bulbs within that 3500K – 4000K because they emit very little light that Is useful to your plant. Notice here the difference between the CT of these lamp’s "

what was your yield after doing that ?

ike the same concept as growers who replace thier hps bulbs two weeks before harvest to increase the potency . I know that if you go pure 2700 k that you`ll most likely get the best yield and nice non leafy bud , but will changing one quarter of your lights to 6500k increase the resin production and thc ?

When people swap their HPS back to MH for the last two weeks before harvest, that's not to use a higher kelvin spectrum.
MH bulbs put out more UV than HPS bulbs do
