250w HPS Club And Help Guide

**Wretched420** · 11-08-2008, 07:43 PM

Hello 250w HPS users,and browsers.
This thread is made to help 250w users to share pix, journals, or any information that helps a user in a 250w enviroment. Most information given is most likely from another source.This meant to be a guide to help and share problems and solutions.

ill start off with some basic information on a 250w HPS.

Lumen output on a basic 250w is around 25,000 - 35,000.this also varies on type's of bulbs.

Best amount of space for 250w is "3 x 3" but ive seen great grows in bigger areas though.

distance from tops of plant varies due to cirrculation of air in the room.
about 5" - 16" is a good range to stay in. the further you light is from the plants the lumen intensity decreases.so keep at a good distance.

also some 250w system's can have a cool tube set up to minimize heat.

250 watts are not as big or a hot as other system's so they can be used in small places great for stealthy grows.

all users welcome to share any information that would help a 250 watt HPS user.

ill share anymore information i find that will help.and please share any information you have..thanks

any please keep the drama out this thread.. thank you

Nice to see you are setting this up. I'm sure there are a lot of folks out there that are thinking about using a 250w setup or currently are an could use/give some advice. I know I for one am on the fence right now between 400w and a 250w. If i knew how to give you what ever points this board uses I would

I sometimes use a 250 watt MH for early vegging for my 3 x 3 x 5 grow area. But once there is some substantial vegging growth to penetrate I switch to 400 watt MH / HPS. I'm sure 250 watt can do the job on a couple small plants, dwarfs of scrog, I just find the 400 watt works best in the space I use.

Hey guys, I recently got a 250 watt HPS bulb, reflector, and ballast. My grow area is small!: 1.5'x1.5'x4'. I'm planning on growing either 4 Lowryder #2s or one dominant indica. I really can't decide.

Anyway, I'll be using CFL 2300K bulbs for vegging and then the 250 for flowering.At first I thought my space would be too small, but others have told me it will be fine with good ventilation. I don't have much money.

Currently I was thinking of have 4 3" holes on the bottom sides of the box with screening over them. 2 on each SIDE of the box. Then putting 2 120mm 110CFM computer fans on the same side of the box near the top on the BACK side. Each fan will blow through its own carbon filter as stated on my post under Indoor Growing(swing by!). Will this be enough?

Also, will the smell of my sweet babies get out through the intakes? They will be kinda close to the plants.

Nice Man, that is a great area for a 250 like you said as long as you have good ventilation youll be fine.. i dunno you would have to try it out. It gets pretty hot. My areais 4 x 4 and its pretty warm in there and i have 1 big 1 1/2' floor fan.
i would go with the lowryder #2.. if you do got with the 1 indica you should top and fim the plant and do a LST method. if you can your area is kinda small ... good luck

Thank you! Some say go 1 big indica, others Lowryder. So, I'm still in the market. I agree t is a small place and I feel ever one big plant would fill it up quickly even with LST.

I'll keep you updated and will be asking many questions I'm sure!
