are you using a closetmaid cab.? i built one with a 150w/hps and a s&p fan and it run 78 all day. any pics?
i dunno its a small wooden cab from target i spent like 25$ on. im still waiting on my 3000rpm 130cfm fan to get here. im gonna use the 130cfm pc fan to exhaust and the 87cfm i have as exhaust now will be used to circulate air around the bulb.

what do you think would yield better, 150 watt hps or 250 watts of cfl ( 6x 42 watts actual)

Most likely 250 watts of CFL.

I'm growing with 120-130 watts CFL and the grow is very similar to when a grow using 150w HPS. Both feaure a single, LST trained plant, both where mainly sativa, and same nutes and growing medium. I guess what I'm saying is, this will provide us with a very interesting comparison between CFL and HID. I'll let you guys now, in about 4 or 5 weeks!

oh, and pics :D this is 4 weeks into flour, another 4 or so to go...

A huge crack of thunder just erupted...gotta log off now. pease!
 
u should yeild more with the 250cfls over the 150 hps. if i was just one bulb id say maybe not, but if its several n u can get source point light via cfls to all your plants then u should be golden, and if mix spectrum or atleast get some blues, your weed will be a higher quality in smell, taste and resin production. hps is strictly yeild.

:yes:

Disco - BEAUTIFUL example of training to reduce height. The pictures alone tell a whole story. One of both method & loving patience. Kudos & Props my friend. PD

DB .. how tall would those girls be if you didn't train them so perfect? That's impressive training right there!

To everyone else : Looking good on the updates!

BC, that 150 is good for about 3 square feet. Light is distributed better if you'll orient the element parallel with the short dimension of the footprint. If your footprint is square, orientation isn't an issue. You'll get about a foot of penetration and you'll need additional headroom for pots, hydro res, etc. If you plan to LST or SCROG, you won't need but a couple or three feet of headroom. Some growers have 4 to 5 feet and have the option to let their girls get leggy. Either way, you're going to get the same amount of penetration and you might get a little less with substantial canopy.

So if I have a 4ft long x 2 ft wide I am better to put the bulb like this

I dunno, it looks like disco has wasted lots of time, not to mention bud sites. You could have flowered and harvested by the time you put that mess together. Or perhaps put lst to good use and spread the canopy out? That would allow you to flower the buds that are now gone.
This surely isn't a good example of "footprint" management.
:dunno:
Or was this for photo op only?

hoosierdaddy: I've considered you a friend here on the boards for a long time, but that's a pretty serious dig there Man. Maybe you just don't have all the facts? IDK. If you have dirty laundry w/DB, why air it publicly? If not, why knock a guy for growin his own?
Jeez, I rep everyone trying to grow their own and having the were w/all to show their attempts in this thread, and no offense to anyone, but I'm sure you'll agree you've seen worse here. But, we're here to encourage one another!
At worst, DB's let a stretchy strain get a bit out of control, and it's quite odvious I'm not the only one here that thinks he did a pretty damn good job roppin em in! And even if you're right about the photo op, so what? It's not all about #s yo! Sometimes ya just got to have fun w/it. See what happens when ya do this, or try that...

Wasted time? Growing bud is not wasted time. If DB wanted to save time and to grow a lot of bud he would get a bigger light. Simple as that. Your comments are unwarranted hoosier. That strain is a cross that heavily expresses Acapulco Gold so you should have at least considered that regarding your criticism.

Look at her without training. It puts things into perspective.

No, they may be harsh, but my words were not unwarranted, nor are they wrong.
I called it exactly like I see it. Maybe someone could tell me how that training could help anything at all? Especially growing with a 150. What it did was put those buds higher up and closer to the light. The time and effort it took to put that together robbed him of bud. I would estimate you could get twice the buds shown, in probably half the time those took by spreading the canopy out and keeping it lower. That is why I asked if it were for photo op purposes. You know, how some greenhouses sell plants all twisted together or in fancy shapes?

Anyway, perhaps we can get Disco to weigh in? Maybe we can find out from him just how upset he gets at a valid critique? Or perhaps he can fill us in on how he critiques others grows???
:dunno:


Again, my critique was spot on, and if anyone thinks what I presented was off base, or wrong, then do please explain it to me. Maybe I am really missing the genius of that procedure?
I appreciate the concern, catman, but I have plenty of perspective, and have a fairly good handle on what is involved with growing sativa.

Looking good in here guys, some very strange plants indeed!

I'm just getting together some equipment for a 150w grow, the floor space is 40x40cm which is roughly 1.3foot. I'm wanting to make an octagonal reflector for the space but I'm unsure of the dimentions to be used, does anybody have an idea what I should be aiming for?

I currently have some Killer Skunk and some Mazar germing in a small CFL box, need to get things sorted quickly.

A 150 gives good light penetration up to 10-12" (24.5-30.5cm) from the bulb. So, no matter how you plan to orient your bulb, you should get good coverage everywhere in the cab you described. If you plan to make a reflector yourself, try to make it fit the dimentions of your cab as closely as possible. If you plan to permanently mount your bulb close to the top of your cab, painting the inside of your cab flat white will work nearly as well, and will be cheaper and less time consuming.
You're cab is a bit on the small side. I'd focus on good ventilation before I put my energy into a DIY reflector. But, that's just my 2 cents.
Good luck, and keep us posted on your progress. Remember, tell NO ONE what you're doing! Stay safe n :smoweed:

Hi guys...another 150 user.

Somewhere in this massive, beautiful thread, I read about someone shortening their lamp/mogul/hood cable that goes to the ballast and hooking up a regular three prong plug, so they could take out the hood by unplugging it. I did mine that way and it works great. I want to buy that 150 digital ballast and use the same connection if I can. I started a thread with pictures here:https://www.icmag.com/ic/showthread.php?p=3521683#post3521683
Would you guys please check it out and let me know if it would work? I can post the pics here too, if anyone wants me to. I probably should have just posted here in the first place....doh!

Thanks a lot all of you badass 150 growers that contributed to this fantastic thread.

EDIT: I'll throw in some pics here..

Hi Vinter, thanks for the reply.
Venting is already covered with an RVK100, I always sort venting before lighting as it saves hassle half way through the grow.
You say the reflector wants to be almost the size of the space? Well that gives me something to work with, cheers for that.

SlowStone, those are beautiful. Hard to say about the size unless you're familiar past yield. I've got a 150w hps and their good for 10 to 12 inches from the bulb.

Depending on ventilation, you can get a 150 within inches of the canopy. This gives much more penetration and makes a big difference.

The only problem, heat is also inches from the canopy. That makes ventilation even more important. A good pc fan blowing on the bulb or between the canopy and the bulb is worth the time and expense, imo.
