LOL, I'll just leave it and be wrong. I'm okay with that. :mrgreen: So I'm guessing you, like myself, spend some time stoned watching the History or Discovery channel.
your analogy was completely fine and accurate. there were plenty of folks who did think the world was flat (i'm sure some still do) but i thought you'd like the trivia. Yes, i do watch documentary DVDs (and many are from the History channel) but don't have a TV (I watch them on my computer) but spend a lot of time reading.

I'm not familar with the new bulbs, how do we know they will outperform the CMH bulbs?
Because of the spectrum that they operate at.
Its nothing to do with anything else.
Anyone who knows about lighting knows that a 72ook MH bulb will do well in veg.
Previously the old Mh bulbs were 4000k and they did really well so you can imagine what 72ook can do for veg.
Basically thats how you know:mrgreen:

Right, but CMH are usable in both veg and flower, considering they have somewhat different uses isn't it hard to say that it is obsolete. While recently I've heard of some people using MH for the whole grow, isn't the bulb you're referring to mainly for veg?

I just didn't want to be the only one out there to bring it up.....
I don't know about the newer MH blub, post up whatever you have about them. But if you want to compare, compare 'em bulb for bulb don't forget about Flowering, Heat, UVB output and Cost. Are better for more than just vegging?

Henery Ford said all cars will only ever run on gasoline.....then diesel engines came out, now electric, solar, hybrids......
I doubt henry ford was trying to make a disambiguation between diesel and gasoline when he made that statement, i think what the statement is meant to convey is petroleum products.

Hybrids still run on gas, or do you know otherwise?

Do you know anyone who owns an electric car?

Solar? Lol.

Despite the advantage of having all the information up to this date in history, you got it so wrong!

Henry Ford said this 100 years ago, and he's still very right. Maybe that will change, but what enormous standard are you holding him to? I mean 100 years!

Henry Ford appears a very intelligent man, as do the many experts on this forum who continually give out advise for the benefit of others. Perhaps you should listen sometime instead of reinventing the wheel, or at least consider that someone who's done this 100's of times probably can tell you more than a spectral intensity curve. I suppose henry ford would have told you to know your role.

I can have a total grow space of less then 8 square feet and still keep the cab in the high 70's/low 80's......and I'm not using a cool tube or an air cooled hood. My plant tops stay about 6" from the bulb, at 4 inches I had slight light burn.

For cooling, a 4" inline fan and a 4" fan blowing on the bulb. That's it!
Um, 8 square feet is not a volume, it's an area.
If you mean 8 cubic feet, of course it's running cool, you have the same volume as a 6"x20' run of ducting, lol. LOL 8 ft^3, you're cab doesn't need an air cooled hood, it IS one!

I mean that is an a tiny space to be growing in, the volume of an 18" cooltube is over 1 cubic foot, just inside the tube!

Even with the tiniest fan you'd be evacuating the air in that cab 10 times over in a minute. Lol, man you come to the wrong conclusion on almost everything, I'm interested to know what you do for a living?

Your plants are ok at best, i do see the conclusive proof that cmh are a waste of time. A 400W 6500k MH using ebb and flow kills that all day son.

Yeah, that cab is a pretty cool design, Thanks:mrgreen:
As for the plants being "ok at best"...... I hate to kill your credibility man but this is what was already said about them a few days ago:
"Nice grow! Bummer about the high ratio of males—luck of the draw sometimes. Like the lemons/lemonade analogy; when presented w/ pollen—make beans!

The extended floral clusters are a sativa trait expressing themselves on an indica structured plant—looks interesting, actually. Will see how these turn out.

As for flushing—the longer the better IMHO. Less productive, but increased quality. Keep up the good work.

Enjoy!

~dj~"

.......that's what the breeder of the beans, DJ Short had to say on my grow thread.....well, like I said before Hash Plant, thanks for stopping by.

I tried to upload some pics that I took tonight but the server must be down. I'll post 'em this week.

This has been an excellent read. Sometimes I get on here, and it's like I'm involved in a soap opera. It's so fascinating-- there are the politics of ego and personality-- there is technology-- there is speculation-- there is learning, there is feedback.

I find threads like this addictive. I have not done anything but read this thread for the past 2 hours.

This thread is like a commons. I was listening to the local college station talk about the abandonment of the commons... places where people gather to talk and exchange information, places increasingly overtaken by corporations, places increasingly small and disappearing due to people retreating into privacy bubbles.

But what the discussion did not even attempt to disclose was that the commons is alive and well.

It's happening in hyperspace, it's happening here, and for me, it's just as real if not real-er (is that a word) because I am listening to people who know a lot more than me on a particular subject and I get to pipe in every now and then and if I want I can send them personal emails.

Whatever rollitup's drawbacks, I really love the format of this site, it seems the most accessible. I went to those sites mentioned above, ICM (International Cannagraphic Magazine) and HG420 (Home Grown 420) but they didn't have the immediacy and accessibility of this site-- I was very turned off by their ugly interfaces. If the creators of those sites aren't thinking about something as simple as that, they'll lose users.

Which is fine, people go where they go-- I personally prefer this neighborhood to those, this one resonates better for me personally, at this time.

As for the egos and bickering... we're humans and this is life. It's still good.

Very well said. Hopefull you were able to gain some knowledge and you were entertained, it sure beats sitting around watching TV.

Here are a few shots from early last week, these plants are currently 3 weeks 2 days into thier flush and stil have time to go. Pics taken under the CMH bulb so true coloring is bleeched out.
Hey man i don't want to rag on you or for you to take my comments the wrong way but you can see from the structure of the buds and the leaves that the cmh bulbs lack the correct spectrum of light for growing with properly.

Even phillips themselves state that they are not efficient for growing with.
Sorry dude to be negative but they just don't have all the needed colours in the correct amounts.
I got my store to stock the bulbs but even the owner and phillips state that they are not good to grow with.

I know its a blow but if you want to put some trust in me get yourself a switchable ballast and use the new 7200k mh bulbs for veg and then put a dual spectrum hps bulb in for flowering.
I hope i haven't offended you as that is not my intention:peace::joint:

No offense taken, we are all trying to learn. I've used the bulb through a full grow at this point, I'm not sure what the spectrum issue is supposed to cause but I haven't seen any problems. There is a number of people growing with them now, Ive seen grows where larger growers used both HPS and CMH using clones. I've also seen people using both together, CMH and HPS. As for my own grow, I've had some pretty heavy hitters watching it, as I posted before, DJ Short commented. If something was up or the bulb caused a problem, I think it would have been pointed out to me at that time but, it's not just him either. I've had 2 different/other breeders that asked me to do a "test grow" for them after seeing my results.....or just to get the attention that the CMH grow thread draws. Either way, I've been offered free beans to be grown under CMH. If all goes well, in another month, my cabinet will just be for vegging and I'll have a 1600-2400 watt flowering room depending on what I work out and with who.

It's not at all that I'm not hearing what you're saying Nat, you've been following the thread very objectivly and you've done a good bit of research on your own. I can only have a great deal of respect for that. We all gained knowledge and that's what the forum is about. Right now, I just have to much backing it up and it's drawn a ton of attention from some well known people/breeders. Phillips didn't produce the bulb to be a grow bulb but with what is taking place, maybe they will look into optmizing it for us.

Email468, I have to say, you have the most orginized grow threads I've ever seen. I got some great ideas from your format. You once made a comment to me to do a "detailed" grow thread, now I see what you meant. Im not even close to being that orginized but your thread helped me get started in that direction. Thanks!

Yeah man i hear what your saying.
I actually asked my net supplier to stock them and check them out and he is now stocking them.

My point is just that they exhibit a strange growth pattern during flowering from using solely cmh and that they are less efficient than using the new MH bulbs in conjunction with a dual spectrum hps.

Heres a link to where i among others got the cmh bulbs stocked at and i hope you get some good results and have fun with your experiment:blsmoke:
