Club 315w lec

Riggs, if youre planning on going with a other light anyways, try opening the hood like I did with the hood I have. It's the same hood and I get much better spread and cooler temps now instead of the hotspot directly underneath. My Grandaddy purples are going nuts into flower further than I thought. I only get to see them in person once a week because of work schedule. I usually spend all week watching them through wireless cameras in the tent.
 
I like the theory on cmh making more use of calcium and magnesium from the available light spectrum. Im going to look it up and let you know what i find. Im pretty good at finding things.
 
Not exactly what I was looking for, but it does look like certain far reds in the light spectrum, such as those found more in cmh bulbs and certain specially designed LED boards directly affect nutrient uptake of different minerals like calcium and magnesium.
Hmmm, interesting.
I like thst they used an HPS as a control as the generic red is what HPS is all about, but looking at the pic I'm posting below you can clearly see clear evidence of how the cmh bulbs contain the far reds like infrared that causes such uptake differences.
Have we ALL learned something new today? I did!
 
I guess this only promotes using gradually increasing amounts of potassium, calcium, magnesium, and phosphorus (maybe not so much this one) when using cmh lights over other lights.
I use flower fuel. It's powerful as hell and fairly cheap! 1-34-32 can easily do a ton of damage if dosing plants at full strength right from the start. I'd recommend starting low dose and increasing dosage each week as I've been doing. But definitely calimagic instead of calmag+ during flower cycles. Sound reasonable? I'm sure tinteastwood could find you a cheap easy way to just add potassium, calcium, and magnesium....if you're able to have the patience to dial in exact needs for your particular strains. I just don't have the time to devote to dialing something like that in. I go with a brand and stick with it to see the end results. I research my nutrients, take advice if i can get behind the idea, and read endless reviews before ever purchasing anything. Im just prone to anxiety attacks over little shit like that tho. Lol

This, while it is about LED's, is exactly the type of information I was hoping to find. It still helps because CMH's spectrum, similar to led's, is much more widely available and hits many spectrums that conventional HPS/MH does not. Particularly with UV spectrums. I appreciate the info, please send anything else like this you find my way if you happen to stumble across anything :) And don't worry I get overly stressed out about spending $ on grow stuff as well...sometimes I just have to clear my mind of the idea and come back to earth for awhile, then think about it again! I'm going to try and make do with my Calimagic, but if I keep running into deficiencies using the Calimagic and Floranova, I'll have to start considering the possibility that it isn't calcium/magnesium I'm lacking. I can always go back to adding Armor Si if it's potassium I'm lacking in veggy, or kool bloom in flower. Appreciate your thoughts on this!

What's your nutrient profile look like? PH? Grow medium? System?
 
Just asking because I like to see how others do things. I'm not the kind of guy that "knows the best way of doing it", and I don't have "the secret recipe". Truth is different ways work for different people, environments, strains, etc.
I'm doing Grandaddy Purple clones from actual Ken Estes clones, in coco from Canna pre-buffered, 2x315 dual 4200k bulb cmh, AC Infinity T6 fan through 6 inch charcoal scrubber for smell, in 5ft x 5ft x 6ft8in grow tent. Canna coco 2 part nutrient, Canna Rhizotonic, Cannazym, CalMag+, Flower Fuel 1-34-32, and Humbolts Sweet & Sticky. Growing in Root Pouch fabric pots, and feeding 3/4 gallon a day.
I'm 3rd week of flip to 12/12. Going pretty well despite setbacks.
Making some changes next grow for Calimagic instead of CalMag+, and other major change might possibly be to use one 3100k Phillips bulb and one 4200k. Not sure about that one. I'm pretty happy with the 4200k bulbs. Might maybe add small wattage light to boost blue spectrums for the veg cycle only. I'm wondering if maybe a 3 foot blacklight might work on either side. Cheap, but effective maybe? Is a blacklight really even countable as blue spectrum?

All you guys using 315cmh bulbs or multiples of, does anyone know what a burnt out bulb looks like?

I lent mine to a mate for the last year, don't even think he plugged it in til last week, then he said it tripped the electrics.
So I took it back to take a look.
Just tried firing it up and it does nothing.
The ballast has a slight noise , like ballasts do, it then clicks every 5-10 seconds like its trying to fire up.

The bulb now has a green/grey tinge to the globe bit in the middle.
I just want to know what a burnt out bulb looks like so I can determine if its the bulb or ballast.
For all I know its been thrown around in transit or he could of half screwed the bulb in or something.
Im hoping its just the bulb. Its a Philips.

One bulb looked like a spent fashion bulb when it died, no denying it was bad, but the other looked normal, I'd say sure could be the bulb, mine died after 4 cycles Phillips bulbs, using eye hortilux now..
 
Well it’s on now, went ahead and ordered the Vivosun 315w ,w 4200k Phillips bulb....I’m running a 3x3x6, think I should still add the blurples (2x 300 galaxyhydro =280 from wall) or is this overkill?:leaf:

Id suggest not adding blurples..why not just add a far red like a HLG QB18 or the flowering initiator kit? I think growmou5 also does a red puck.

This inside stuff is totally new to me... and I’ve damn near studied more on lights nutes soil pots etc etc...overthinking shit...but thanks man... as well as all the good smoke, I most definitely want it to look good..checking into it now
 
I cut my hood around the edge and undid the tabs to open it up from a ( shape to a { Or [ shape. Gets rid of the hot spot under the cmh bulb and you can run light lower and not worry about height problems. Gives much more even light disbursement also
 
I can see the spread reflecting... seems to let heat escape as planned.. also I’m a barber.. so my eyesight is extremely Important... will my led glasses work or do I need glasses for a cmh.. and covering the skin from the UV rays are all safety precautions.. like OSHA
