Trichome Production By Different Lights

Agreed, you also add can use sulphur additives too

Thats more for flavor.. And we can add synthetic hormones for a boost too... I dont like adding stuff. Fruits like sulphur but we dont smoke em...i don't like terp or anything but a dry booster

Uvb increases oil.. Gland and changes the chemical make up of the trich cuticle

Double ended is the superior choice from what ive personally seen, ppl pulling 3 per light, with quality as well. Different strokes for different folks, sixstring kills it with cobs in just about every department including yield.

The DE hps has more of the Uvb than the 630 cmh and any SE hps , correct? I dont have ceilings for a 1k gavita but ive been looking at gavitas 600/750w DE... do these 600w de gavita give the same quality as a regular 1k de gavita and theres just more 600s needed to light the same space?

Hey, I was just being honest about my growing skill. The skill of the grower has nothing to do with light physics. I am doing whatever I can to increase yield including building a lighting system and a UC system. Each harvest is bigger than my last and that is my goal. However, when it comes to light I have the engineering credentials to back it up but I am not interested in dick wagging about yields but I am interested in the science of horticulture and making each grow an improvement over the last.

When people use gpw as a barometer of light ability, it always tickles me. Shove one moe plant under it and BOOM goes the dynamite

There will always be a few growers hitting it out of the park with big numbers (they are the least likely to brag), there will be some who hit the good numbers and a bunch of us struggling to get there. I just like to be straight up about real yields and real issues. I hate when people exaggerate the numbers (not pointing at any particular person). It makes it harder to figure out where the bar really is. I think in a community of people one person's success is everyone's success and I hate it as well when someone rips into someone else about their achievements or lack thereof.

I like real data. I keep a really detailed daily journal and record every bit that I can. I like the challenge of growing this plant though. It's never as easy as it looks. I am experienced in light technology and some physics etc. (been a farmer, greenhouse builder/operator, orchid grower/breeder, grafting specialist (roses)....) but as a cannabis grower I feel I am into it far enough to recognize common problems and solutions but need lots of refinement to get the numbers up.

Dee, I couldn’t agree with you more. Like you, I’ve never reached the insane numbers I’ve read people getting. I know more is possible and welcome the challenge. Since I grow mainly for myself, weight is not the be all/end all but it’s certainly fun trying to get there.

I don't need your approval for shit. You sound ignorant to the light game

the light game? ha okay.. let me check out your diary

Yeah, my first priority is quality which has not been an issue since my first cycle but even that one was better than dispensary stuff. I also grow for a veteran that has some serious PTSD so my concern about yields is mostly borne out of the need to grow enough so I don't run out before the next harvest.

Keep in mind it's just a weed, and an extremely resourceful one at that. It find ways to survive the harshest environments and the most egregious of pilot errors. I certainly screwed things up big time stubbornly sticking with the NPK RAW nutrients, but learned a ton in the process. This knowledge plus the great results from my new lp aero seedling/clone starter system should pay huge dividends once the plants are transferred to the flood totes. I am expecting to have 2 plants transferred tomorrow morning

I don't grow for numbers by any means. I grow quality first. I don't even keep track of total yields anymore either. If I got homies that need, then we can make a deal. I only grow for myself, and my friends and family. I got tired of buying crappy herbs for any amount of money. Been growing my own for over 2 years at this point straight. Harvest once a month

Not an expert here but I have seen some evedence that UV stimulates some trichome production as a way the plant protects itself from too much sunlight but then there is some evidence that some LEDs like quality COB systems increase trichomes. One thing that LEDs and CMH have in common is a very high CRI in the range of 90 or more out of 100. When you see high quality COBs or CMH the first thing that stands out is the white color like midday sunlight.

One thing I do know from studying phytochemicals is terpenes are all about defense against bugs, mold, mildew and animals that want to eat the plant. since plants cant run away they use chemical warfare in the form of monoterpenes, diterpenes...etc. So, one big factor is genetics, then stress. Some people stress the plants to increase terpenes but IDK if the light has a big impact or if there is any conclusive data. I recently completed a couple of flower cycles with COB 90 CRI lights and was delighted with the results but what is really needed is several side by side runs with differentm lights with all other conditions identical.

Dee

I agree, terpenes are increased by stress . I stress my plants by rubbing Branch's and stalk also cut random leaflets off , not hole fan leaf.

some of what you are saying i agree with. But you are forgetting spectrum. plants grow differently under different spectrums. I said i don't think LEDS are quite there yet, meaning with technological advances i think they can and will be. what you said about cost is definitely true. it a high cost of entry. i worked as an assistant manager at a hydro shop and ran a warehouse and delivery service so i have experience in every facet of the industry. only thing i don't know and wont do on my own is set up the electrical work. i leave that to the professionals as i don't want to burn down the building. we sold every time of light and every type of set up... i have had hour long debates with sales reps, customers an coworkers. nothing could produce weight like a 1k hps. hortilux was the best back then, but things are changing now. Numerous DE hps(with mixed in LEC/CMH ) like a 70/30 splits in a stationary high point area is the best way to do it in a warehouse. which is the only way to go as residential electricity is too much money. this is strictly indoor though. i would love a greenhouse with supplemental lighting. that is the future for most. a couple niche indoor brands will survive and flourish though. as far as a closet grow LED would be a great choice. it doesn't run as hot and will cost less to run. but for anything serious LED is not the way quite yet. hopefully it will in the future. would be interesting to see how it turns out.

hopefully you will find the year 2018 ..and learn how you are incorrect

and of course you are saying this because you have leds yourself and know this to be true

and you are saying this even though there are piles of people who have switched and will never go back....

And even though the person you are telling that "leds are not there yet "knows the difference and even posted

photo's of his buds..

there is nothing more leds need to do now except become dirt cheap..however the drivers never will

so i would say they are ready now..and I had my first HID/HYDROPONICS SETUP in 1979..

the light game? ha okay.. let me check out your diary

Where is your diary or at least a pic of bud from your 1000watt de,maybe your gpw????

People that brag are fuckin idiots... Hey do a big bud and then a grinspoon... Yup... 3 a light ok

 

[Leew421]

I don't grow weed for numbers by any means. I grow for quality. I merely reference numbers as jumping off point as to the performance these light can put out. There is a reason big operations like MedMan run these exclusively. It's not because we are getting shitty results. I did shit tons of research and have used cmh, hps, mh, t5s, florescent, cheap LEDs, spydrx plus, spydrx. Note, I put them in a category all in their own. These lights are next level and not for everyone considering price point. By all means run your bulbs, all I'm saying is don't throw blanket ignorant statements out like, "LED is not there yet" it needs to be, cheap led and blurple lights aren't there yet. Anyone that cuts corners on lights and goes the cheap route will get cheap results. While you figure out how to manage the heat from your open bulbs, I'll keep mine 6 inches above my plants so the lowers get nice and huge. This is an open forum to express opinion and antidotes of success and experiences. I hope your grow is bountiful, and everyone here I hope can get what they grow for and not feel bad sharing it. This is a great site.

 

[iloveyoutoo]

as far as a direct comparison to DE HPS they just are not there yet man. maybe you are the ignorant one for thinking that. medmen is running their grows from a business perspective and it makes sense. it will cut the electric bill by a lot and lower heat issues... im not saying LEDs are bad, but they just arent the same as DE hps.. like i said earlier i think they possibly will be the future.and with moore's law in affect, it will get there. but not yet.

 

[Leew421]

You keep telling yourself that.

 

[iloveyoutoo]

same to you

 

[Leew421]

When you can afford one, you will see.
