Disagree.

My research tells me that:
Low Kelvin/warm spectrum (3000k) or so-called "warm/red" light is best for yield.

However, high Kelvin/cold spectrum (4200k and up) or so-called "daylight/blue" light is best for overall potency, flavor and particularly terpene production.

Several sources have told me that the only thing low-kelvin/red/warm light is "better" for is the yield. Everything else, cold/balanced light is actually outperforming the low kelvin lights.

So I will definitely look into the Hortilux fixtures. Thanks for the tip, I lost sight of those!

I will go with high kelvin or daylight spectrum throughout the entire grow, both veg and flower.

I kinda figured this out a long time ago. A buddy of mine was always changing lights, configurations, etc. I began to notice that the weed that was grown under the 1000w halide was ALWAYS stinkier and more potent. There's obviously many variables involved...but it became pretty obvious after a while...to the point that I would go over to his house and ask which weed was grown under the halide and would buy that.

The HPS weed had bigger yields...but always lacked that magic punch and taste. .02

It's really strange how this seems to be common and even ancient knowledge for many yet the majority seems to have never heard of this.

It's looking judgementally at me and asking me how long till it can fulfill its purpose in life

My next step is mixing my soil, testing, getting the water tested, hand in both results here and ask the smart heads if the soil/water combo be good.

Parallel to that I have to continue construction on the room itself and then prepare the veg chamber so I can start.

Still a bit of work ahead of me before I can fire the dimlux up.

lol … sounds like a bit to do, but nice doing something that is fun, eh

Seems this 'hobby' gives the most of any imaginable … get to research cool gadgets, look at amazing canna porn to pick the seeds of choice, play with tools and dirt for hours. And at the end … ahh

have fun mate and enjoy the dimlux sparking up for the first time … centre of the sun time.

Has anybody an idea if a 315w bulb would work propperly in a 210w ballast?
And have you any idea in wich way the spectrum would possibly change?
I am thinking about tryinng it out but im also afraid to damage this expensive gear

personally i wouldn't brave it and try.... get the right gear to run the right bulb.... reap the rewards for doing things "right"

Hi AV ... I was reading through the threads again and a couple of your grows ... wow ... nice one.

I really like the different type of setups you've tried and used. Your advice above is a good reminder for me as well.

I was wondering what your thoughts are about the welthink all-in-one fixture that you've been using for awhile now ... I think you mentioned that Rocky Mountain Hydro sold them.

Thanks

I wouldn't try it. The lamp is the load, the resistance in that side of the circuit. Voltage being equal, higher output lamps designed to use more power have lower resistance & will therefore stress the ballast more than the proper lamp. They may not operate properly at all.

Philips went the other way with their current lineup of CMH, offering lamps that give the same amount or more of usable light at lower power than the lamps they're designed to replace. They're marketed as easy money savers for commercial lighting & def work well as grow lights. I get excellent results using a 330w to veg all sorts of seedlings.

i got my wellthink all in one (non-remote ballast) from Rocky Mountain Grow Lights.... a single guy in denver who basically only sells th 315w CMH with wellthink ballasts.
they are working really well for me, i love the cmh especially for veg. they beat the pants off the t5's i was using previously.

thanks for the advice, and looking into my threads, hope me sharing my exp. helps you... in some way.

pug1010 · May 15, 2016

Thanks AV … your posts have helped greatly.

cannaisok · May 20, 2016

Thx to rives and AV and all the other people thet provide us with necessary information.

@AV i have seen u use bamboo sticks in ur grows as support for the stems. As far as I know even plastic sticks are better than this bamboo with lots of herbicides and fungicides in the upper painting. All my Plants started to feel better without!

Thats all. Ty

Just got a 630 lec and a 315. Rooms covered in panda and was wondering if some of you think those lights can efficiently cover a 3X7 flower room. Runs 12 ladies.

Now they only sell SunPlix CMH grow lighting.

You can use SunPlix dimmable 315W CMH ballast/lighting.

Been telling them sunplix for weeks, all they see is "cheap chinese ballasts".
I was behind welthink and I'm now behind Sunplix.
But you seem to be dealing with a different distributor .
I believe mine (the distributor lives a couple blocks from me)
Catalyst Lighting. Watch for the soon to be released digital lfsw ballast to run the allstart 860 or most any lamp for that matter .

The "cheap chinese ballasts" have sold many thousands of units internationally and proven their ability to stand behind the product while revising their design. That's a pretty good track record for a product rollout.

I did a yahoo on "sunplix" and got 6 results. And you know the distributor personally?? "I was behind welthink and I'm now behind Sunplix". It sounds like you have a horse in the race.

Y'know, If you do an Alibababa search on cmh grow lights you might recognize some of the chinese reflectors and cmh lights. So, if someone in California bolts a ballast to a reflector........

Take a look.

I have no horses in any race but my own, I am not affiliated with anyone that doesn't hang commercial ductwor or appreciates Sauvecito anejo tequila.
Yes I've met with the distributor twice to buy 315 ballasts but other than that I've talked shit on facebook about their distributors/customer support and how they don't seem to appreciate the customer unless he's buying a crate of complete lights.\
Anything I didn't address?

dbkick · Jul 4, 2016

Also I've dipped toes into cmh 315 other than philips due to a hydrofarm phantom issue thatr I'm sure only the select few that got the defective units know about.
Sunplix so far has exceeded my expectations if you compare to phantoms.
I run 315 gear from pargrow to philips to ushio to solis tek to sunplix.
At first I went with the overpriced (unless you buy at the shop I do) SS lec and must say these are nice units but I want more than that.
The featuree of a sunplix ballast and a decent vertical hood fit the bill even more than the SS lec but I'm still in the testing phase. Next up is the og hoods and sunplix 315 ballast with wtfever lamp I choose to run.

Nope. We're good. I just had a "hey wait a minute" moment there. You bring allot to the table with knowledgable and well founded info. In fact, when I first suspected 'the flicker', you confirmed it and that got me on the phone with Hydrofarm. Your cred is excellent.

what is the recommended light distance from the plants with 315w cmh with air cooled hood
thanks

this is a photo of my current setup, is there enough height for 315w CMH.
any opinions on moving the filter outside the tent for more room/height?
