Nice cab, Krakatoa. The bulb will distribute light better if the fixture is hung front to back. Don't know if it would fit that way or not. Looks pro and stealthy.

true true nice work krakatoa very stealthy
Thanks for all the kind words guys! Just fired up the 150 HPS, and WOW! Temperatures are 70-72 degrees. As of now, I just have a high velocity fan for cooling, which seems to be pretty effective. Although the temps are steady, I plan on purchasing better ventilation/carbon filter, but in the meantime things are looking good. I understand that the 150 watt is effective for about 4 plants. However right now, I have about 9 just until sex is determined....is this okay?
Also, I should note, that they have been outside vegging for about 3 weeks, and are each about 8-12 inches tall.

Yo amigo! Congrats on the 150! Remember it's not about plant count, it's about square footage of coverage. If you could fit 100 plants in the space that gives 50w/sqft, then in theory, you would be fine. (You'd be trimming all the undergrowth and fans to keep the light on the buds, but it's in theory)
I currently have 5 lollipopped under my 150 with room for about 10 more. But... I'm running single- or dual-cola lollipops; when I scrogged the bitches (6"x6" screen attached to the pots) I only ran 2 in the cab per run.
Keep playing and asking, you are right on track!

First any amount of plants (2-10) will work under a 150. It all depends on if your growing variety really. Instead of the buds being more concentrated on one or two plants it'll spread them out over nine plants. Also a 150's light penetration is only like a foot foot and a half if they're 8-11" then I'd recommend switching to 12/12. Height is a big issue usually you don't want them to get to tall. Also as I'm sure you probably know that they stretch to 2/3x's the size they're at now. just trying to help
Wish my temps were that good, FIRSTIME. Depending on the stain and style of growing, 9 plants might work just fine and 4 may fill the entire grow space. Some strains flowered early will make a nice cola w/o taking up too much room. Others will look like a bud on a stick and need more veg time, a different grow method or both.
You mentioned your veg plants are a foot tall? A general rule of thumb estimates anywhere from 2x to 4x stretch with average being between 2 and 3 in my experience. LST is a good height control method and SCROG will get you a more even canopy with the potential to maximize the sweet spot of your light and grow. Since you have the potential for multiple females, you could go with a SOG or natural grow, taking advantage of the stretch. With some strains, a 150 will get you colas and the highest buds on the plant. Lower growth won't benefit from the light as much and yield will suffer. If you don't have the benefit of headroom, some type of training might be the way to go. Stems are easy to break so be careful. A thirsty plant trains easier than a fully hydrated plant and will result in less stress IME.
If you don't have the benefit of knowing what your strain(s) is gonna look like, take your best shot with what you have. If you grow the strain again you'll have a better idea how many plants you want to fill the space. Keep in mind that some states may penalize you by the plant numbers, not total yield.

With just one or two plants, the 150 can do real nice stuff with a properly cared for scrog.
You can get by with other methods and do near as good with the higher wattage bulbs, but the 150 is best used over a scrog if you want the most bang for the buck. More than 4 plants can be disappointing with the little 150 if you don't take extra care in training, unless you 12/12 from the first set of 3 fingers.
Just me 2 pfennig...

i agree completely. also after the third week does stretching continue or does it start to slow down?
Stretch is strain dependent.
Zombie Virus 3 weeks veg from seed. The little one is a T-Haze clone just getting it's roots on.
The ZV is Indica dominant. I'm told it doesn't stretch at all.
The T-Haze is Sativa dominant. It'll stretch a good two weeks, maybe a little more.
The parent, Haze is a full blown Sativa that will stretch throughout the grow.

Once again, thank you all for the valuable insight. Head room is not much of a problem, and because I am so green (pun intended) I am pretty reluctant/apprehensive for LST. After reading all your helpful responses, I think SCROG is the way to go, in order to maximize efficiency. I pretty much understand the concept, as I have done some research. I was wondering if you guys knew of any other guides/threads to look at, or just any general knowledge.

Thanks Disco I'm growing nirvana white widow and was wondering where to go to get that information.
Sorry Firstime, I'm a LST man myself.

Hey First, I did a search in advanced under "scrog" in titles only. I got this as a return.
Happy reading! Oh, and look at posts by pico in the thread - "I dont understand the scrog seems like a waste of time" - some great scrog pic in there, and only 3 pages!

I was just examining my girls and noticed that every node from the top to bottom on one plant is female but on the second plant all from the top up are female but i noticed one ball on one of the bottom nodes. Whats this mean?
It means yer gurl swings both ways, lol. Seriously, it means the plant is capable of pollinating itself and or the other female. The trouble can range from minor to critical.
Keep an eye out for nanners. These are pollen flowers that look like tiny bananas growing out of the bud. They're usually lime green or yellow and fairly easy to see. Remove them carefully to keep pollen from spreading.

Thanks disco do you know where i might be able to find a pic
Hey Guys,
Odor control? I have done plenty of research, and understand the carbon scrubber is the way to go. However, at this stage I have yet to buy/install one. I have read about the DIY ONA bucket/fan, and was wondering if guys think its a practical solution, at least for the time being....thoughts?
Also, I have read that when using SCROG you should switch to 12/12 when 70-80 percent of the canopy is filled during veg. Because of my height, I switched to 12/12 a few days ago....I was wondering if it is to late to incorporate a screen, since the plants have yet to be trained around the screen.

Check this link, in the post he has a couple pics of some of his buds with a nanner or 2. make sure to click the pictures for a bigger view. They are hard to see in the pictures, but you can easily see the difference in color vs. the buds. And if you catch them earlier on they will stand out even more. Hope that helps, DB may have some better input or pics for ya.
Peace

Look at the scrubber RedGreenery built on this thread. I use the exact same thing, works great and easier to build than a DIY can to me. Plus it holds more carbon....
When you flip is strain-dependant bases on the stretch of your girls. If they stretch a lot, then flip earlier and keep training till they stop. If minimal stretcher, then flip when the screen is fuller. If you just flipped, then I would build your screen and position it so that when you are done weaving and tying the growth you currently have it is 75% of the screen (I am assuming that at this point you have no idea how much she is going to stretch.) If it stretches more than you expect and the buds are too close to the light, then reach under the screen and pull it back down a little to keep that canopy even.
As long as you are just starting your flower, the plant is still transitioning from veg to flower (takes 2 to 3 weeks) and you should get on it now. If it's more than a week or two into flower, then it's too late and plan your scrog for the next run.
If I didn't explain this well enough, let me know. I'm at work and thinking about my chemistry analyzer more than training a scrog right now! lol!
