Missing trichomes with LEDs?

Angus I am new and I am using LED...why so many dont understand why I did post my question and what I am really asking for...

> Because I have seen some threads that led is not able to produce real trichomes.. Don't listen unfounded claims, I have great results with current generations of LED fixtures, I made my own concentrates and don't have any issue with trichomes (wtf is "real trichomes" anyway?). I guess they are using old tech (like CoB or blurple or just shitty noname quantum board), don't understand that LED have to be used differently than HPS lamps, are just covering for a bad harvest or just trolling around.

why I am asking ( answers didnt help really except the sunlight of course)... I plan to switch from led to cmh for the final stage of flowering... Because I have seen some threads that led is not able to produce real trichomes...reffering to both...size of the heads and the real milky or amber color. Thats why I wanted some comments from experienced led growers

Nothing, I repeat, NOTHING, beats sunlight! But there is no truth to stalks and artificial lighting, it ALL comes down to genetics.

> The only thing I have seed about trichomes with different lighting styles is if there is UV involved. That's right. But more specifically UV-B, which has an impact on terpenes and flavonoids and not directly on the quantity of trichomes. But it's a very powerful form of radiation that needs to be handled with care, both for plants and for humans. UV-A, on the other hand, emits very little energy, particularly in LED format, which can be found in certain fixtures or booster bars with IR-A diodes (nicknamed "neoblurple"). And as there are no UV-B LEDs… ^^

Light is light. Spectrum is spectrum. The differences is heat. Light intensity that isn't accompanied by the heat does cause a negative outcome in some instances. According to Harley Smith.

The only thing I have seed about trichomes with different lighting styles is if there is UV involved. UV causes trichomes to be produced as a defence against the UV, Its not needed indoors though the plants will still produce just fine. I also agree genetics are a massive factor on how well it turns out. Good Luck!

I totally disagree. But I'm curious to known what make you think that. On the contrary, the arrival of LEDs on the horticultural lighting market has made it possible to question old knowledge about photosynthesis (from PAR to ePAR). Because LEDs emit a narrower range of frequencies, they have made it possible to carry out more precise tests on the best ratio to use to promote photosynthesis (researchers have even gone gone as far as refining this knowledge on the ISS). So we've gone from incandescent lamps with a gas chosen because the radiation is closest to a need supposedly linked to chlorophyll, to modern fixtures made up of SMD LEDs whose light spectrum has been specifically designed for horticultural applications, with higher electrical efficiency and greatly improved homogeneity of coverage and temperature management. That's all. And the quantity or colour of trichomes has nothing directly to do with light, since the former is a self-defence measure and the latter a sign of maturity.

Hello my friend, I used to grow with HPS and now with LED lamps. The only difference is that with led the grow room stays a lot cooler, I need to water less and the Led is more efficient. So I get more grams per used wattage from LED. I use pocket microscopes to check the trichomes and did not notice a difference between both type lamps.

More likely genetics. Plants don't look bad, but also seem to only pop 3-5-fingered leaves which indicates some imbalance in nutrients, but even so, still think it's 90% genetics. can't polish a turd. no matter how perfectly a plant is grown, it's ceiling is its genetics. You are too early to worry about trichomes. when the buds are plump and physically resemble something you'd smoke, then you can worry about trichomes. If you look early you can find amber early, because taht's normal degredation that is occuring at all times. the 'trichome' signal for harvest is more art than science. Trying to guesstimate an average over the entire plant when you cannot see 95% of the trichomes buried underneath newer growth. The old stuff probably isn't clear and digging around in a bud isn't wise. If you harvest and don't mine experiementing with a bud, pry one open and scope the internal calyxes. bet it has more milky/amber than the outside. trichomes, pistil coloraion and density of nugs are 3 things you can observe to help determine a harvest date. They are all useful to some degree, but none are perfect.
