No crystals

I just harvested my first crop under led lights. Wonka bars was the strain. The buds did not frost up at all. The buds are dense with a lot of hair but no frost. I'm not sure what I did wrong. My humidity was around 50% the whole flower cycle. I used floranova bloom, koolbloom. Water ph proper. Strong light. Good airflow. I think it may be the strain. Cause a few other plants got crystals. But I'm kinda down about it. Not gonna have that much good quality. It smells real gassy though.

Not necessarily true.

Trichomes are great, but not all strains are frosty.

Smoke and see, might be a delightful surprise.

My HLG Rspec boards don't make the buds as frosty as the CMH, but they make them more dense. I like to run them both together when I can. QB's with CMH is my favorite combo. Dense and frosty.

I see. Are led know of making buds less frosty?

Yes. CMH is known to make the frostiest buds. I think it's the UV rays.

I sometimes get strains that lack the frostiness but have more of an oil to the bud. They are usually sativa based with a ton of hairs. You may have to try a different strain next grow. If it smells grassy you may have harvested it early. I like to hang branches and let the buds dry on the stem before trimming. It seems to keep the aromas in the bud. You might have harvested early and wet with too fast of a dry.

Its a learning experience, I would suggest a different strain. It might have been a really long growing sativa.

If you don't have trichomes and the plant is in an otherwise healthy environment then it is going to be the genetics, not the light.

I've had plenty of frost on plants grown under led, and HPS, neither of which has any UV in them.

The whole myth that you absolutely have to have UV in your grow comes from the idea that THC is used by the plant as a kind of "sunscreen", so by giving it uv you force it to create more "sunscreen". This is, of course, a ridiculous notion as it would mean that HPS lights wouldn't produce a good quality product, which they most certainly do.

Also...I should point out that using lights with significant output in the UV spectrum can be harmful to eyes and skin if you spend too long exposed to it.

UV=Woody stems from what I have seen.

I wouldn't immediately blame the lack of perceived frostiness on the lights. I have an OG Kush under some spiderfarmer 1000s that has trichs so thick I keep checking each night expecting to see it actually develop into powdery mildew/mold lol.

Could be as simple as that's the phenotype expression under whatever conditions you were growing in.

I've grown cannabis under Mars-Hydro TSW-2000 LED panels for 2 years and the statements that LED doesn't create frost is complete bullsh*t. I grow under HPS, CMH, LED & T5 and FROST is strain specific so long as everything else is dialed in (water, food, environment)..

Room Humidity & Temperature are only the very basic environmental factors when it comes to Cannabis Cultivation. There are many other factors like VPD (correlates with RH/RT), co2 content in the air, light distance/output, medium growing in, airflow etc..)

I would say you maybe didn't flower them long enough or it just is a non frosty strain. I had some Gorilla Glue #4 from GrowersChoice seeds and it was trash. Grew huge nugs but they were completely resin free weak. I threw it all away. I'm a cannabis medical user so I can't have weed that doesn't work and I'm not going to pawn it off on someone else.



Here is an example of some frosty Gelato I grew for a few runs under the Mars-Hydro TSW-2000 Panels.

No, that is a myth.

If LEDs make less frost than CMH I must be dreaming. Proof or its bro science.

lol...Any chance to show off ...I'll play, since I'm showing this off everywhere I can anyway I'll add my current HPS-only grow

I just did a majority of the wrong strain. This was a different one under the same light. Turned out good
