ok guys I have a question for you. I have a tiny cab. 30"Hx26"Wx16"D. Do you think I could get away with a 250W cooltubed HPS in there with an ambient temp around 75-80F? I already have a ballast and bulb and would rather not buy a 150 or cfls.

Use a 6" inline fan and maybe. I'm running a 4" inline no cooltube but aircooled reflector in a 3x3 and I have to dial my ballast down to 175 to keep it below 90 Ambient temps 80-85

Dont have a cool tube I have a sealed reflector... But it goes like this Carbon Filter ----> Reflector----> out of Room So its pulling air out of my tent through my reflector and out of room.

for the 250watters who scrog. How tall are your shoots when they stop stretching during flower?
I understand that some strains will grow taller, but how tall do you prefer them to be?

Here is a couple plants that i got going at the moment. Pics 1-5 are of one that only has a couple weeks to go and the couple are of one that still has about 5wks left. I grow with the light hanging vertically and the plants placed around the light. I can usually fit 5 plants that finish around 2ft tall and i can get around 1oz per plant. And these plants are 12/12 from seed. For the height limits that i am faced with growing in this little flowering room 12/12 from seed works great. I'm not going to go into much about what strain i grow. It is a local strain and i am the only other person besides the person that has the clones and seeds. I have mainly been growing the seeds and so far i have gotten 100% females with them. I am planning on moving up to a 600w hps setup and i have a spare 5x7 room that i will be growing in. But i may still use this little 250w setup and just use them both. But i want to be able to supply myself a year off of just a couple grows a year. I never sale any and it is all for me. But with using the 250w i am having to constantly have a grow going and since i grow from seed they never finish at the same time. I want to move up to a 600w setup and push for as much of a harvest as i can with it just a couple times a year and that would free up alot of time for me. I have never really went away for a vacation for more than a couple days in the past 3yrs because of constantly having something in flowering. I am going to go ahead and start 4 more seeds tonight. Hopefully by the time those finish i will have the 600w setup running. I will post more pics of these two plants within the next couple weeks when they are closer to being chopped.

Not sure I understand the question. All the stretching takes place under the screen, so it is hard to say how tall they are when they stop. The screen is 8" above my Blue Cheese, so that's as tall as they get. In terms or length, I would say they stretch 18" or so. Another way to think about it is that when I switch to flower, the plants fill 2/3 of the screen; the rest is filled in with stretch.

My question goes a little beyond the filling the screen 100% part which is usually the goal. If i am able to figure how much to fill the screen completely, but want to have longer budsite, 6" instead of maybe 3" for example. How long would each budsite/cola, would you prefer it to grow to?

I don't stop training the branches until 10-14 days into the 12/12 cycle. After that, I let them grow uninhibited (except for tucking some fan leaves back under the screen). Except for the buds around the edge of the screen, they finish off about 6" long. The buds should be more uniform, but my current reflector sucks-- an upgrade is in the works.

I'm 2.5 weeks from harvest-- tomorrow morning, I can post a photo with a ruler to give you an idea of where I am at this point.

The 250w gives 6-8" of useful light penetration, which constrains the size of the buds. You can routinely get that size, particularly if you use a cooled reflector and get the light as close as possible. Sadly, I singed the tip of one of my buds under the hot-spot in my grow-- which is the price of not having a cooled reflector.:cry:

Would a 250 watt mh be good for vegging in a 4x4 room? If so how many plants could be comfortably vegged under that for a 6 week period? Thinking of getting one for veg in the future, at the moment using 3, 90 watt ufos.

i have a 250w with a internal balast. its got a slot where i can put a sheet of glass or whatever they use in there. but i am struggeling with heat issues. there is no hole in the light system for ventilation. i mean i cant hook a inline up to it what can i do? i got 2 106cfm fans one for intake and one for outake. what can i do to bring my heat down?

What size of a space are you growing in? Is the space in a small closet or a room? What's the ambient temp of the room as well. I've heard of heat issues with the internal balast systems. You may have to get better fans for a faster air exchange due to that balast being enclosed and giving off alot of heat itself.

thanks nitegazer. Don't got no pics but my shoots are definately too long. A lot of the fan leaves are yellowing and dying off, but no buds really on that area. I read a chart that said 5" to 16" optimal penetration but my bud sites don't look like it'll be 11" of herb, although the shoots r longer. any other input from other scroggers?

Wow....I've been in the aerogarden thread. Nice buds guys...check mine out. SCROG cabinet with 250 HPS. Just ordered the agro 270 watt bulb. Any opinions on it?

kinetic im growing in a 36in height 36width and 20depth cabinet i topped my plants so they are about a foot and a half tall and stay about 5-10in under the light. do you think if i throw a household fan in there up towards the light on full blast that it will be enough to push the heat to the exaust better to suck it out of the box

I would get a clip on fan, set it on high and aim it up. It should definitely help, from my experience 5-10 inches is a little close, if it's hot to your hand underneath the light at that level it's hot to your plants. Happy growing!

image494i.jpgTHIS IS MY FIRST GROW WITH 250W HPS AFTER A FEW UNSUCSESSFUL CFL GROWS WHAT A WASTE OF TIME/MONEY AND EFFORT THAT WAS IM BUZZIN WITH THE OUT COME OF THIS GROW THE ONLY BAD PART BEING THEY HAVE BEEN FLOWERING FOR OVER 11 WEEK EVEN THO THEY'RE 8 AND 9 WEEK STRAINS 100% CLOUDY TRICHS A COUPLE OF AMBER ONES HERE AND THERE GONNA CHOP SOON

SEEDSMAN MAMA MIA:hump: at the beggining of flower it exploded with growth faster than the big bang i actually had this strain mistaken with bigbang for the first 3-4 week of flower coz the big bang was said to have explosive bud growth this strain has a spicey hash/skunk smell it has also threw out a few male bananas:cuss::!: right at the end of flower nothing bad tho just single ones here and there i just plucked em wiv the missus' tweezers i love the way this plant gives solid buds even on the lowest braches they are all solid im not keen on leafy bud prefer some solid nugz


GREENHOUSE BIG BANG:hump: this strain stayed small i picked the 2 strains coz they supposed to stay relativly the same height i had to put the plant on a upturned bucket to give it some height there isnt much smell to this plant in flower yes it does smell of an apple cut in two but not much else really now in the later stages some purple has started to come thru looks kinda neat the buds have really swelled up in the later stage of flower my buds n this are kinda leafy not too bad but pretty leafy the other day the cola looked done i didnt check it for a few days and when i went back in the grow room the cola had produced a load of new bud growth and new pistils:confused: the big bang is the one with the fatter cola on the left in the last 2 pics

:joint:when its dried il post some pics and smoke reporton these strains id just like to say THANX to all the members for all the help you have dished out to me and all and all the other people with sticky green finga'z :weed:
