Hi guys,

I am new to LEC/CMH.

I have only used HPS. I have used a 600w hps for over 5 years and always got nice dense buds that were full of crystals and plenty of taste.

I recently purchased some DE 1000W hps.

I have been doing research and it looks like 2x 315 CMH are similar to a 1000W hps.

I am guessing to match a 1000W DE hps you will need 3x 315CMH?


Now to my question! :

I have no doubt the spectrum is better with CMH, I am concerned about penetrative vs 1150W DE hps. Ultimately you only have 315 w vs almost 4x that from the HPS!

Anyways my question is will 3x CMH out perform the DE HPS?

Is it worth me changing? Are the results that much better??

I mean if it makes plants finish a week earlier then I'm already half sold...

You won't have any issues with penetration or bud density if that's a concern, as long as you have decent coverage over the whole of the area you're trying to flower out you'll be fine. My experience is they'll cover off up to about 3.5 x 3.5' each, with some overlap from multiple units they'll perform even better.

As far as outperforming a DE with 3 of them, I think they would be close but no experience with DE''s. You should do a run or two to get a feel for what they can do, I think you'll be pleasantly surprised. 2x can come close to a regular 1000w, probably more like 900w. I think you'll find the quality, quick flowering times, lower draw, and lower temps will sell you on them. I'd run 2x 315's vs. 1x 1000w any day.

OK... I'm going to invest in 3x 315 CMH.

Once I have done a grow with those, then only cobs are left for me to try (have used LEDs with mediocre results).

i would use three 315's to cover a 4x8 space/table. Most people i know would use 3x 600's or 2x 1000's to cover the same space.
I must be honest i have no experience with double ended Hps. What i would suggest is if you are in a legal state and are not worried about electricity run the Double ended's.
With the double ended Hps you will need A.c. and high ceilings. I can say i have now heard of people in my area setting up small scale commercial grows 100%on 315 LEC.
I have done alot of growing with a standard 1000w bulb in my day and i used a 4x4 max area for a single ended 1000w, but if i under stand double ended hps correctly it will cover a 5x5 space and then some if your ceilings are high enough.

I think the perks to LEC would be cover the same amount of space with less watts, runs cooler, better finished product. Penetration is not an issue with LEC
As long as they are spaced about 3.5 feet apart or less you can not go wrong with LEC and you wont go back to HPS.

My results may not be typical but i can crush 1000w hps with two LEC's.... That's just me i have them well dialed in.

Im not really big on taking pictures but here are a few. All plants are in different stages of growth i run perpetual for the most part.
This is a 4x4 tent with 1 lec. Most of the plants in these pictures are pretty early in flower so you dont get a good idea of what the canopy will look like.

I would take Gro's word on this matter.

(but 3 will do even better.....and still use a bit less energy)

Also looking to upgrade lights Best prices iv found were 280 for nanolux and another 80 for the bulb so 360.the phantom for 380 and the sunsystem for 440.wnted to know if anyone would recommend one light over the others and why

I've got a Phantom and some SunSystem LEC's. Both are good and can get the job done. The main difference that I noticed was that the SunSystem had slightly better canopy penatration.
Other than that, the only difference is that the SunSystem has its ballast built into the unit, where as the Phantom's ballast is not.
The SunSystem would be my first choice but the Phantom is still a worthwhile purchase for those on a budget.
