Buds quality LEDs VS HPS

[ttystikk]

I ran the same numbers as you suggest and come up with about 8 years.

If I factor in the loss of heating propane savings and add in an electric heater to make up for the hid heat lost I would never recover anything really.

And I do use high line equipment and bulbs.

And I expect a complete reliable pre built lamp. I don’t want to build. And I am positive the lights you are suggesting will be old tech soon anyway.

'insulation'.

I totally understand why HID is your best choice right now. Anyone who's using the waste-heat from their grow to supplement their home heating would be well-served to remain with HID. I've said it before.

However, I am a bit perplexed by your "old tech" argument. After all, HPS is old tech.

Edit: If we were to use more realistic figures for this comparison, that 8 year ROI estimate would be reduced even further. So I in no way consider HID a clear winner on the cost-front.

Water cooled LED did a fine job of keeping my home warm last winter.

Low power specific color diodes are what is needed to customize a horticultural led spectrum. And what is being designed by the light manufacturers. Not full spectrum high powered cobs. Pretty sure they are only sold to weed growers.

And of course light bulbs are old tech. I couldn’t even buy a twisty bulb for my kitchen at wal mart. Only led replacements.

Anyway. I don’t Grow for greed and I would have to put out almost 3k for the led lamps I want if I was to rebuild.

I’m so slow to upgrade I only got a cmh last November. And it was no upgrade like the forum consensus states. It cut my yield in its space 30%. Please understand my caution.

'insulation'.

Yes you keep saying that and I keep telling you I live in an almost 100 year old rebuilt cabin with an open to upstairs rock form basement.

Only so much we could do here for insulation.

And the numbers for the lamps I want I stated did not include the heat savings is what I said.

You are the only led proponent here that has not offered any proof or even factual numbers to consider.

Just your word repeated over and over.

The other growers here show results worth considering.

I am sad that no one has commented on the conclusive testing and info from the university links I put up.

But no one ever does in led. The info does not support cobs.

To each their own.

Do any of you legal USA growers know the cost of sending a sample of bud to be tested for THC content? Or any other testing that can be done to solve the argument of "which is better".

 

[hillbill]

Before I totally switched to high end white COBs and LEDs each minute was costing me more each day every day. Every week and every month. Now I just use the extra $ for seeds or crankbaits or something.

You said it cooled the lights too much and caused problems and had to shut it down.

Stop bending the truth to sell led. You don’t even have a company and you sound like a half trained rep.

Perhaps that's because at this point in time it simply doesn't matter. Any advantage that mono-diode based LED fixtures have does not negate the value and performance of COBs, boards, or strips. They still rock a garden like a motherfucker, and they're still an improvement over HID for many growers (not for all, clearly). When the mono lights start hitting the DIY market at prices comparable to the current white-light, full-spectrum LED options, then it will matter in a practical way.

If thc content is the only factor in a perfect grow the lamp with he highest uvb will win.

Unfortunately there are too many variables even in a side by side. They are all over the Internet.

Cmh usually wins for thc potency alone. Led usually wins for terps. Why? Science. Uvb is present in cmh (and hps and mh) and not in led.

But led runs less radiant heat and cooler temps promote terpenes.

Now factor in the individual grow and we don’t know what caused what.

True, and even the LED manufacturers think we are nuts for using them this way, but even so, it kinda works.
The millions of tiny LED options are a nightmare thermally if you want to remove the heat from the room.

Spend 20 bucks and get a UV fluorescent tube if it bothers you that much.

I hadn’t thought about diy multicolored diode lamps. That is a complex diy.

And any production Greenhouse or indoor set up today would know exactly the spectrum their plants are getting and why.

They supplement the sun or control plant growth with light science.

And I have never seen cobs in any of them. Some are using lumigrow and some other multi diode led’s

Most use de hps and cmh still.

You think that's the only way I ran them? Did you ever stop to think that maybe you jump to conclusions a lot?

And they're not for sale. You can't handle the truth! Lol

Have a look at some of growmaus's shit, he makes a nice far red initiator with 3 3W 730nm diodes.

I am good as is for now is the point.

I would need 4 tubes to cover my garden and the fixtures for them and I don’t want all that either. You all want me to spend so much money for no reason. And time.

It’s kinda weird how important it is. You just agreed with my main point about the warehouse led’s being repurposed even.

I only am repeating your words. Too bad you make them up as you go.

 

[ANC]

What do you think HID is then?

I saw that. Don’t the expensive pre made horticultural lamps have that and uv already?

And please ANC. I am not arguing about the lights being able to do the job. Just if I would invest in them.

You are making my point about tech now. The small diy style builders will not be able to compete. Or even keep up.

 

[MichiganMedGrower]

What do you think HID is then?

What do you mean. Old tech from street/ warehouse lighting originally?

They have already evolved and still are.

And they still work great.

 

[Buba Blend]

Points, condenser, bias-ply, drum brakes, generator, sealed beam, vacuum wipers and HPS.

Fax machine, modem, DVDs, CD writers, VHS and Betamax

hilarious my brothers!
IMHO some generators will be loved long after we are all gone!
Until then Happy Growing!

Post them up then. Been asking for weeks for people to post side by sides. Post aways my friend.
