Honestly I'm surprised 1.5 is perceived as an outlandish claim at this point in the game. There are factors that limit yield, PH to high or low, to many nutes, not enough nutes, root rot, too much water, not enough water, humidity too high/low, canopy temp to high/low, insufficient air exchange, etc. but when everything is dialed in there's no reason why people shouldn't be hitting those numbers from mid to high yield strains if the lamp output provides at least .5 par watts per watt.

I went from .7 GPW under CFL to 1.25 under 35% efficient Vero 18, just like that. Results under gen5 Vero 29 at .7 amps was always between 1.45 and 1.68 GPW over various strains. I had some experience under my belt at that point but I'm not a master grower or anything. Perhaps my expectations are unrealistic

These people are just old school and stuck in their foolish and incorrect understanding as the world moves on. I wouldn't be too concerned about it.

LEDs and COBs are two different animals. COBs were invented to replace HIDs in highbay/lowbay industrial applications. LED panels weren't. Your ignorance is showing hard.

We have been talking about COB's the entire time buddy. You're back tracking and playing semantics now trying to deflect.

A cob is a form of white phosphor conversion. Just as are many LED's...1w 3w 5w, 1/2w...
A cob is 130 to 200+ single LED's put onto the same substrate and covered in one silicone LES. It is simply a tight group of small single LED's.
The fact that you don't know that and try to use COB as some mystical form of led is just adding to your delusional status that you have been expressing for the last couple of pages. And if we really want to get down to it...COBs are made from mid bin wafers...single dies and smaller packages get the good wafers...that won't change anytime soon.

Please learn what you are trying to "teach the world". And please complete a grow and get some experience before you go making a fool of yourself. It will help you, to not embarrass yourself, and help others by not having to read loads of false bullshit that you have no experience about but put forth like gospel.

Speaking of deflection, has anyone seen Hybridway's 10-12 lbs. under HID or 2 lbs. under a 600w SunCloak yet? Pretty sure I asked for proof he has yet to furnish.

25-35% of the forum had seen my 10 & 12# HPS room, (& I regret being that sloppy) as well as my 2# SunCloak harvest. That's why nobody but you is calling it BS big guy.
I don't play when it comes to growing.
I'm sorry Rahz has you believing your 241w of tasty is a 600w HPS equivalent.
Actually, I highly doubt he told you that. Show us the e-mail.
@Rahz , you never told this guy that the light data #'s on your site are hypotheticals based on math equations using Cree data-sheets as your foundation?
Those #'s are not from an actual par-meter unless he has updated his site or something.
I'm sorry Olive. You're plants are no bigger then my 6" Potts.

His plants are smaller than the ones i grow in a tiny veg tent under 2x 60w Equivalent CFL's.

Output is based on the same type of data bulb manufacturers use to rate their output and efficiency. It's mostly apples to apples if everyone is providing manufacturer data.

241 watts output at 50% efficiency = 120 par watts. Very nice for his space but that's not going to be the same as a 600w bulb, nor have I suggested it. I do agree that Olive Drab is shooting from the hip which isn't doing him any good but that is not my fault.

I think it's going to turn out pretty damned close, especially accounting for overlap.

241W COBs at 50% efficiency is going to produce 600umol/s at best. A 600W HPS produces much more light than that.

You are probably comparing a matrix of PPFD measurements in an open room. Common mistake.

This is incorrect. Mine are producing 830-932 micromols of PPFD per light at 14-16".

This is the shooting from the hip I was talking about. PPF is a measurement of umols, but there's no such thing as micromols of PPFD.

The 50% efficient lamps I've sold run around 2.3 umol/j, so 241 watts of it will provide about 550 PPF. This puts your PPFD around 735.

735 PPFD in what size area?

I provide the data I would like to have access to if I were purchasing lights for myself. Using manufacturer data is as real and fair, and free from opinion and personal bias as it gets. I wouldn't purchase an LED based lamp without knowing the radiometric efficiency.
