Club 315w lec

[ThaMagnificent]

My clones go from t5 to 315 cmh 4200k and I raise the light way up(3 feet) and after a few days I lower it a little, I continue this until I get to 20". I do not run cooled hoods. Some strains react better and some react worse.

Yea I went back to the 150mh on my moms and they bounced back. I ordered the 3k bulb so will install that tomorrow

It's called the first law of thermodynamics, you might want to pickup a basic science book bro you have zero understanding of how heat works.

Watts are a measurement of energy.

read this thread if you still cannot grasp this

Here's a quote you might want to read to get a better understanding of heat.

I love how when people disagree online there first actions is to insult the others intelligence. You do not know me, nor my intellectual capacity. As far as I'm concerned this conversation is over. Can't be respectful then I don't have time for you.

It must be nice to be that ignorant.

Good comeback. You feel like a badass yet for attempting to talk shit online?

I own and operate over 22,000 square foot of medical cannabis greenhouse space.
I own and operate one of the largest industrial hemp farms on the east coast.
I've consulted over 50 farms ranging from 2000 light indoor cannabis operations to 25 acre corn fields.
I regular give speeches at two local colleges that focus on agriculture about organic IPM.

I have more real life experience with horticulture than the average... I will stick with my conclusion that it isn't as simple as a formula.

Disagree. Agree. I honestly do not care but do not disrespect me. Not once did I disrespect you. Can't have a conversation without name calling I'll simply block you. I get on this site very rarely because of the way people act. People have other opinions, and are allowed those opinions without be bombarded with names.

Next run, instead of smoking your stuff, just go ahead and burn your enitre crop and see how much that burning plant material can heat up a CC of water. That would give an approximate measure of energy your plants consumed and converted to chemical potential energy from your fancy heat makers

Isn't this about the same process we use to find calories in food?

So, I wandered into my local liquidator store to pick up a seedling mat....
There in front of me on the shelf, is a factory sealed box, containing a Sunburst 315 CMH with a Phillips 4200k bulb.... for $150....
There's no way I could leave that just sitting there right? I didn't. I brought it home. I had to.
As a DIY LED enthusiast, I have zero experience with CMH, but I've been quite curious, and tempted to get one for some time now, so I feel like today was a bit of a stroke of good fortune.
Had plans of a new build in the works, but now? This honey ought to suffice for at least 3x3 of a 4x4 tent right?
Absolute worst case, these are fantastic VEG units?

I love my Sunburst 315-have the 3K lamp . . . Paid like $375 for it.

If you have all that space and setup how do you not know how to calculate basic heat loads....kinda makes me think you must not be that great a grower.

Following a elementary math formula isn't the problem. It's the fact I do not think that formula applies to this situation. We just gonna have to agree to disagree.

It's a law of nature, it's why it's called the first law of thermodynamics, it doesn't matter if you think it applies, it applies in every situation because laws cannot be disproven.

Anyone like to talk about the 315W CMH?
Heat is an issue only if you let it be.
Environmental controls are the key, get your room is order an you should not have a heat issue. It took me awhile to learn that and even though it is not perfect now it is close.

My ac barely.runs in the winter, basement setting with 4x 315 in ac hoods. It does cycle more last 2 weeks when I'm dropping temps to finish my girls off for harvest.

 

[gr865]

I set the AC that is in the room I draw air from @ 70 degrees when lights are on, that keeps the tent @ 78 to 80 degrees. Lights off, I do not use the AC, just the house temp pulled into the tent. House is set at 76 degrees so by the time it is pulled through the tent, the temp is in the low 70's high 60's. I will be running the AC with lights off starting this week, my 7th weeks of 12/12, to get the temp around 68 in the tent at lights off, as I want a good 10 to 13 degrees difference between lights on and lights off. Get them buds tightening up nicely.

Platinum Purple Candy #8 bred by InHouse Genetics.

Light dep supplemented with 315s.

Plants put outside February 12th supplemented till March 21st. Deps pulled April 16th to keep flower schedule. Harvested June 1st. Greenhouses refilled and supplemental lighting started again. Shouldn't need as long of a veg this round before flipping again. Trying to get 4 runs out of each houses this year.

Co2!

The power/ ac cost saver. And more yield to boot. It's a win win!

I only get down to 70 my last week of flower. Freeze them girls.and they bust out their purple coats (leaves for those of you who can't keep up)

Update:

Day 49 about two weeks left to go.

Buds are just fattening up.

The heart of this plant. Check out the growth around the crown of her trunk, should I try and re-veg her after harvest. I don't think so, this is a lot of work.

That is an amazing spaghetti bowl of branches there!

I know LSD. You will enjoy this product, I am thinking.

Yeah Java, this is my 3rd grow of her and her sisters, 5 pheno's to start, then 4 of pheno #1 and one of pheno #3, and now this monster crop which is pheno #5 of this strain. It makes some of the best medicine I have made.

I had to go to a slightly bigger fan and seal up my ventilation system. I absolutely love my 315 . . . and I would guess the heat is only slightly greater than a 250 HPS.

Are you running your ballast in the same tent as your plants, if so you should look at separating the lamp and ballast.
I did, only took an extension cord.
