315w is it really comparable to...

106 posts in this topic

I was looking to buy into these CMH's myself tbh :g: but I dunno so much now see, the LED work I'm seeing about the boards and also with the rigs that can be tailor wired for all sizes and shapes seems to put them at an advantage from my pov...

 

If I'm honest I think these CMH are too expensive at the moment to sway enough people, even though the lamps may last longer and better flavoured weed etc, it's that initial outlay and when you're skint as fuck.   A 20 quid Sodium is a guranteed lamp that will provide buds that can run on an old mag ballast that can also be purchased cheaply and of course being simply engineered, longevity without technical incidences are reduced accordingly.

 

I'm swaying more towards LED more and more for the future of my growing (and I NEVER thought I'd say that a few years ago lol ), They are definitely comparible, from what I've seen, with other systems and look to be the future for most lighting applications :v:

@ratdog, yeah, me too. Well, no, I'm 100% sold ~ just a case of When! And what with? I tested out Mrs L's reaction yesterday. Was expecting her to point at the emptiness that is our kitchen, and the absence of carpets throughout the ground floor and the same in one bedroom, a bathroom (with a leaking bath) and the landing. Let alone the fact we need rather a lot of furniture. Or maybe she could have pointed at the yet to be done wet-room?

 

But she didn't. Asked why, so I trowelled it on a bit (could smell the possibility of the impossible actually happening), and mentioned increased potency and yield, and then wielded the hammer-blow "Even @oldtimer1 has changed all his!"

 

Silence. Hmmmmmm, the glimmer of a smile as I pointed to our jar of pennies (one of them big old jars that used to hold toffees and sweets ready for weighing out when I was a nipper, which is now pretty much full with all change 20p, 10p, 5p and so on).

 

She's not said yay, she's not said nay.

 

Now what the fuck am I meant to make of that? Could get messy if I get this wrong ....................  :fish:

 

 

 

5 Minutes later....

@botanics Aaaaaaaaarrrghhhh!

 

That's torn it, I'm off oot with my dogs!

Your house sounds like my house! I had one of those big jars for change, £200 in there when full! Just buy one! As we know, it's easier to gain forgiveness than permission!

@Joint hogger, Do you mean "Fox-tailing" or are you talking about stacked calyxes? Blues will stack calyxes like mad if left in 12/12 long enough (say 9 - 11 weeks), but I've never seen her produce fox-tails. Lots of people use the word Fox-tail when they really mean Stacked Calyxes.

 

 

is stacking of calyx a good thing a bad thing or just a plant specific trait? or does it indicate something else?

@Badders I thinks its a good thing. More to smoke, how could that be anything but good.

Fox-tailing isn't "bad", mind. Most Sativa sizzlers look dreadful , but hit way above anything more "eye catching".

 

So called "Bag appeal" is just plain marketing talk.

 

Folks need to learn that what you see tells you very little about what you smoke.

@Arnold Layne and @botanics

 

Hmm the advise I gave Arnie, is based on my personal observations, ie its anecdotal on my part, my breeding over the years has used these same observations in selecting the most psychoactive parents carrying the traits I prefer.  

 

I test and select each plant I keep and mother up. I have grown each line under just HPS, just MH a 50/50% mix of the two types 600 +600w, same clone line grown in the south of france, cob lighting and CMH.

 

The most potent was grown in the south of France, close behind was CMH then quite a bit behind the mix of hps/MH mix very close to that were the Cob panels Then MH and last and by a long long way HPS with the poorest psychoactivity of the lot. 

 

All this has absolutely nothing to do with yield, only the reason most people smoke weed ie, what it does when you smoke it, its potency and psychoactivity.

 

My conclusions are that the more genetic potential within a specific variety, the more the potential is expressed the nearer you get to ideal growing conditions. Light is one of the biggest contributors to ideal expression.

 

A lot of plant lines bred for generations under the limited spectrum of HPS no longer have much in the way of potential psychoactivity and will show little difference in expression no matter what light or sunlight they are grown under, its very difficult to select for psychoactivity when breeding under the limited spectrum of HPS lights, you can easily select for lots of trichomes, large buds etc but hemp grown for fibre can be loaded with trichomes, but they don’t/can’t get you high.

 

I am not denigrating LED lights, but the buds they produce just don’t make it for me compared with buds from the same clone grown under CMH. So CMH are my top recommendation  at this point in time. I understand that cash croppers  may poo poo this but thats not what I’m interested in, this info is for those who want and appreciate connoisseur quality buds.

 

As a side issue I use white led’s for mums, they are not quite as good as fluorescents but cheaper to run and cuts soon pick up when under a good wide spectrum light.

 

I hope this helps explain part of my reasoning. Ot1.

 

PS on sats I put  oldtimes mothers cutting in the greenhouse border at 4 inches tall in early july, it went up like a rocket, I tied her to horizontal, today she has spread to 7 ft wide and the tallest sidie is over 6 ft high

you can see all of her as some is round the corner behind the tomato.

Well, that's me convinced. Only reason I smoke is effect so bring on the cmh , nice one @oldtimer1 brilliant summary 

 

Peace

@oldtimer1 thanks for that. :) Did you use the 942 Daylight lamp for veg and the 930 Agro lamp for flowering? I was wondering if the 942 Daylight lamp would be sufficient for both veg and flower? At least for a while anyway, until I can afford the extra lamp.

Hey, @oldtimer1 love your work. Which cob panels did you use? 

 

A Photons a photon. 90cri CMH and 90 cri l.e.d photons are the same. Theres no two ways about it.

 

The only difference between CMH and the newer l.e.d's like cobs or pcb leds is efficiency. Thats the ONLY difference...and for the record, the new leds are head and shoulders ahead in the efficiency game. 

Oh and their lifespan too...

 

Hortilux just announced led/de hybrid btw

such a charmer. But it's actually you with your head in your ass, sir.

 

@Badders is right. l.e.ds are leaving CMH behind

@oldtimer1 Out of the thousands of different cobs and endless kelvin and cri combinations which ones did you test out of interest?

 

Cmh has limited options with bulbs, leds are endless so just saying "cob lighting" isnt giving the full picture.

You know the score @Key4 

 

LED > EVERYTHING ELSE

 

Better efficiency, so that's more photons and less heat per watt than CMH or HPS, single or double ended.

 

More spectrum options, including fully customisable light spectrum controllers, so you could if you like, mimic the time of day to have redder mornings and evenings.

 

No bulb changes.

 

Better in awkward small areas. 

 

Better light spread for a more even ppfd, particularly with the PCB style leds - offering penetration in every corner.
