Have you looked at my thread? Ever? I kicked HPS to the curb years ago and my per plant yield average has never been higher.
2x400w versus 1x1000w

He's still trying to cram two bulbs in there, and he can use these just as easily. 315W bulb n ballast kits are $200. Wire it to the reflector of your choice.

actually, i remember when you joined this forum. i did not have this account, and you did not have this led experience. I've been trying to justify spending money on led's, but since my 8 year hiatus, i'm going with what i've used, and what i know that works. It may not be a 14kw system, but we're working on it. btw, did your vertical goodness ever pan out the way you expected? as i said before, i'm curious if the baskets give you a vertical canopy equal to above lighting (as you can't turn plants when you scrog into vertical screens)
you and i used to be friends in another life (and with a different name). can't we all just get a bong?
seriously? fo rilz b, i swear, you and me were tight a bunch of years ago...

HOLD IT. LED? The light to which I am referring isn't an LED.
315W CMH lights are still HID lighting.
I'm on record in my thread and elsewhere that I'm still halfway thru a disappointing first run with COB LED, but these ain't those.
Trying again, 315W CMH lights are like mine hanging in the foreground, and that's a 600W HPS in back;
As for the rest, things are a work in progress.

Hey, I just saw your post. Which COB (Chips on Board) LED are you referring to and can you post the link to your thread here?
There are lots of COB LEDs coming up and a lot of the companies advertising them don't advertise the actual draw - they just advertise total watts.
LEDs don't run at the total watt amount but rather 40-60% less. Companies from China, Amazon, Ebay listings will advertise total watts so they get more short-term sales but end up with unhappy customers. Always make sure you know what the actual watts are before buying something. If you are unsure, contact them. If they don't reply then you shouldn't even deal with them because if your product that you bought stops working then you are SOL when it comes to getting your money back - stuck with a paperweight.
COB LEDs aren't bad. 550 Watt Scorpion COB side by side with a 1000 Watt HPS

If you want more photos /closeups just pm me and I'll send the latest.

That side by side study really means nothing unless there are no variables different between the 2 rooms meaning
- same strains of clones cut from the same momma in both rooms
-the same feed schedule
-same feed strength
-same medium
-same temps/humidity, etc.
This side by side mentions none of this.
Also, can you provide links to the rest of the side by side grow?

2 400's. Considering also what everyone else said as well regarding heat ventilation canopy penetration and space. I was reading about running a 2 light cycle for seperste veg and flower rooms and getting half pounds every sixty days. That's where I would upgrade. Or rather...will.

The feed schedule, strength, etc was more or less similar. The temp/humidity is not as accurate since they were done literally side by side next to eachother so heat from one might have affected the other. There were more tests done a few years back as well. The bottom line is that we already believe it ourselves since we've seen it with our own eyes. It's not something you can really convince someone of with photos.

We're going to send you one to play with, and another grower also wrote and wants to try the Allstart. I think it'll be a good project!

so there is more intensity and light quality coming out of a 1000w? because this is what i am really trying to figure out.
beside any heat issues and shit.. i know about all of it
but, is the 400w never going to equal the benefits of a 1000w no matter how many i stuck inside the tent? i mean, even if i get more watts from 400w, let's say, i would stuck 3 pieces inside a tent, will the intensity of a single 1000w still be better for the plants? for bigger buds, actually, cause that is the goal..
i know that the canopy penetration is better with the 1000w. but is it something beyond that? or if i get the same number of watts, the results will be the same?
and, aside from this, do you really think that 2x400w are running hotter than 1x1000w? i keep reading everywhere how hot the 1000w are. and now, running 1x400w i can manage the heat really easy and i don't have good exhaust.
so, i thought that 2x400w would be more manageable than 1x1000w. but, hey, this is just my impression, i'm not saying i'm right. i am a noob, that is why i am asking.
and, can you please tell me what is your exhaust set-up and what hood? you made me really curious about it when you said you have your plants 4" below. that 60cm was just an example, but 4" is really close
)))) i bleached some top leaves of a bud at 5" under my 400w.. but as i said, my exhaust is really amateurish, as is the light, so i know for the next run an upgrade is a mustthank you!!

now this is too big to fit inside my tent i guess, but i love the pyramid shape. i am searching exactly this kind of hood. i never understood why the smaller hoods have the sides parallel to the walls, only the front and back are in a diagonal plan..

yes, the 1kw is much more intense than two 400ws. i'm using a 8'' ipower fan and filter, 765cfm. keeps the glass on the hood cool to the touch.so there is more intensity and light quality coming out of a 1000w? because this is what i am really trying to figure out.

the sunsystem hoods would fit, they are six inch... we have two of these, but are switching them out with the raptor 8'' hoods

My hps ballasts are getting old and ive been thinking about replacing them... and with both you and Gro Err raving about these LECs... think im going to go that way.
So... how to cover a 5x9 space with those? And... what might i need to cool em? As i understand they dont have a/c hoods...

They 'can' ..... I have seen some OG hoods that would work...
Issue is the LEC/CMH or whatever they finally choose to call them..... Mount vertical, not u need a hood designed for vertical bulb mounting.

I can make them work one way or another. I just not sure how many i would need for 5x9... and how many a/c btu id need for cooling...
