LED vs. HPS

[Loganr888]

are leds better then HPS and do you need differnt lights for each stage does anybody know i think im going to switch for power purpose but i need to know if you need differant lights and which types of leds anything would help and what siz LED will grow the same area as a 600w HPS thanks for any information

you can look at my album or my thread in my sig..i got some nice LED's :smokin:

[Loganr888]

but do the colors make a difference for stage or is it the same color the whole way threw need help on this i have to change from hps everyone said its the best thing since sliced bread any suggestions

From what I have heard, LED's are good for supplemental lighting, but NOT for primary, you should never stinge on lighting because yield will show you that you are lacking by the end.

HPS is definitely the right choice, start off with MH for veg, then when you go in to flowering, switch to HPS.

MH uses more of the blue spectrum of light, imitating that of the summer sky. HPS for more of the orange/red spectrum which the plants will use more during flowering (imitating the fall sky).

I would say stick with the MH/HPS, and if you wish, add LED as supplement. Growing solely on LED would not yield anything worth mentioning.

In this you are quite incorrect.
I have personally had excellent results.

See, now you have heard mention that they do produce.

Check out Str8s grow, then you will have at least seen that they can, indeed, produce.

Please do tell us what you actually know though.
That, is much more useful to everyone, yah?

No offense intended.
There is much to learn here.

Yes, Logan.
Whatever light you choose, a little extra red during flower helps trigger maturity and seems to add bud bulk as well, though I have no proof of the latter, it's just what I have read.

I have, however, personally found that cranking up the blue at onset of flowering can limit the pre-flower "stretch".
Changing the Red:Blue ratio is easy to do with LEDs.
It's the 3rd reason that I use them.

The first 2 being;

1. >half a buck per KWH.
And.
B. It gets hot here.

The 4th reason, I gotta admit, is the ness factor.


Aloha and good luck.

HELL NO! LED TECHNOLOGY WILL NEVER CATCH UP TO HID FOR GROWING CANNABIS! THERE IS NO REPLACEMENT FOR DISPLACEMENT, THE END!

Tsk!
Inside voice B.W., inside voice.
But, thank you for your opinion.

the problem is most people that have tried LED have fell into the "snake oil" sales of promising more than they can deliver....then there is the skill of the grower....i am glad we got some experts here to let me know that these LED's won't flower

Where do I begin?

You're dead wrong.

LED versus HID in the EXACT SAME WATTAGE, LED wins every time. Proven time and time again.

For example, there's a video on youtube, doing a solid 90w LED versus 400w HPS.

At the end of it all, the 90w LED yielded 31g. The 400w HPS yielded 93g. Assuming yield increases linearly with power increase, a 270w LED would do THE EXACT SAME as 400w HPS.

That's just a bit over 5/8 the power usage for the same amount of product.

Also, for purely visual purposes, there's not a single HID on the market that can compete with Cree's 200+ lumens/watt LEDs.

Any further statements you'd like to make without posting any proof?

Hang on, I'll post a picture as well. Looks like my plants are doing just fine (minus the nute burn on the ones in the back right.) and starting to bud just as well.

I'm going to have to agree. BW, ur a DB. If you are just going to regurgitate the same BS other people are slinging, do yourself a favor and zip it. You just make yourself sound like you wear a bib and a helmet.

Pic is day 20 under LED flowering.

BW, where's a pic of your show?
