Is This To Much Light For This Room ?

We are nearing completion of our room and are ready to buy a light. The room is 45" x 45" and 50 inches from the floor to where the light will be. The room is underneath stairs so there is additional room just no additional growing area.

I have seen several links to this; https://www.htgsupply.com/viewproduct.asp?productID=47981 and want to know everyone thoughts. It just sounds to good to be true, ballast, reflector, MH lamp, HPS lamp.

I have installed a 4" duct with an inline suncourt fan to get some of the upper air out of the room.

Is this to much lamp for my little area ?

Will I need a another 4" duct pumping air into the room ?

Should I have gone with a 6" duct and inline fan ?

Thanks,
SuM
 
Can you vent to the outside of the dwelling? Any fresh air in?

the light isn't too big..it's too small. I would go with a 600 and an aircoooled and would figure out a way to make the ventilation work.

you won't be sorry at harvest and the extra $$ upfront now will seem like nothing.

Currently the 4" inline fan is venting to garage, its the best I could do. I could get air from

A) The garage but the temps are never constant
B) The furance / AC room a little better, but I am unsure how warm this gets in the winter
C) Between the 1st and 2nd floor is about 12 inches with insulation. I could clear out some insulation and pull from here. The air is always cool.

Can you recomend a site ? I loved the combo on the other site but am willing to pay more if a dealer or mfg comes recomended.

If I understand correctly you want me to feed fresh air through the reflector and possibly pull air from it as well. What about the rest of the room if I do this ? These ducts eat away at my space :)
 
Thanks for the link above I will check out their site next. I am assuming you meant hydro.

Here are a few pictures and my plans which will hopefully spark some other suggestions for my build. Keep in mind my wife and I dreamt this up late Saturday night.

We have an 8 foot deep coat closet on the middle floor, I cut a 2ft x 2ft hole at the back for access under the stairs. After a few hours of vacuming and wiping down we were here.

We began by removing ONE support from the ceiling to give us an extra 7 inches, painting, and re-enforcing the entrance. We used eggshell white thinking it would be the easiest to keep clean and dust free.

more painting and removing of overhead nails.

Ran a 4" duct from the garage to the room to air out.

NO pictures from today but we finished painting and have added a 4" inline fan to what you see above and ran it to a high point in the room. Also added 4 outlets to the room.

Tomorrow I guess we will work on getting AIR into the room from where I am undecided at this point. Plus we have vinly flooring to lay down and seal with some cheap trim to catch water overflow.

The entrace to the area dumps right into the heart of where the plants will be. I am working on something that will have all the plants on pallet of sorts with wheels to slide out of the way to gain entrance.
 
maybe this?

Lumatek 400 ELECTRONIC ballast. Burns both hps and mh. Silent running.

Hydrofarm Value Cool Tube - Lumatek ballast grow light system from 4 hydroponics.com by Growco Indoor Garden Supply

Cool Tube---would ROCK in yer space. Takes up less room that a boxey/square hood and jettisons heat from the space well. With a 4 to 6" adapter the fan you have might work.

I'd still go 600 if I could swing it...but the 400 will be fine and WILL stay cooler for ya. Some of yer space...way up under the lowest stairs in unusable
I wouldn't figure this into my calcs...and would probably mylar it off at some point so not to lose light in an area where there's no bud.

Check Ebay too. Lotsa deals there...

temperature will be your challenge.... at least that's my guess.

good luck

600w in that tiny space? You're insane.

It's not the square footage that's the problem - it's the height, he's only got just over 4 foot to play with! Even a 400w HPS will probably generate too much heat in that area. He needs to be looking at 250w HPS's and possibly CFL's or linear fluorescents.

One of the biggest advantages of 600w and to an extent 400w HPS's is their light depth penetration - he's only got 4 foot! So it's hardly an issue is it?

This guy needs to have a rethink about his lighting and ventilation.

Looks like a vote for 400 watts or lower. Today I returned all the 4" duct and fans. Going to 6" with 2 inline fans and a stat to watch the temp. The first fan will blow out to the garage while the other will pull air from a small space next to the furance room. I am headed up now to keep working, I may be able to post some pictures tonight.
 
Yes..I am insane. Thanks for noticing.

And YOU use WHAT type of light yerself...babygro?

RECAP....it's 45 x 45 and he has 50" of headroom...

Ya remember tearin my room apart and telling me I had no clue..blahdeeblahdeeblah, babybro??

Prolly not..you *help* so many here it must get confusing keepin everyone in line...offerin up advice as ya do....huh?

Anyway...KIA..*my* space is exactly 50 inches tall....and I run 2 1000's and a 600 (all hps) in 3 seperate cool tubes in there. The footprint of the space is just over 8 x 8'.... In my veg area I run a 600...same headroom. In the clone area...2 4 ft t-5 4 lamp fixtures... roughly 4000 watts in a 12 x 12 space....all with 50" of headroom or less...(I have the scars and scrapes on my back from 15 years down there to prove it)

In another thread from today you HARSH on the entire thread full of posters...telling them to NOT RESPOND if they don't know what they're talking about... Same goes here babybro.

Im NO EXPERT...never claimed to be...but I will assure you that if I comment I've tried what I'm talking about and have the experience...successful or not..to back up my words. Have you EVER grown in a 50" high space with HPS lighting? If so...carry on... If not...STFU because it is now YOU GIVING SHIT INFO AND TALKING ABOUT THINGS YOU KNOW NOT OF...

Glad to see goin forward/goin 6" Sunshady..moving air will be the key to utilizing MAX light. MAX light will give you MAX yield.

Take my advice or leave it. Or you can follow advice from those who've ONLY used CFL's but speak towards hps as if they use em daily and have years of experience doing so.

good luck w the space

i say go with the 600watt system with a glass coverd air cooled reflector...if you can swing it eathier get a switchable mh/hps ballest....this if grown right will give you short thick budded plants...
 
Thanks for the replies, I will keep looking for a light tonight. Here are some pictures from today.

The floor and trim are done, we are debating on a system for drainage.

Finished up the electric

The inline fans are currently in the room for a dry run, they will be placed elsewhere. The outbound will go under the floor and the incoming will go in the furance room. Alot louder than the 4"

ImageShack - Hosting :: room006xk9.jpg

This should give you an idea of the height. The ceiling is 57" tall but I am growing in only 50" assuming the light will use 7".

Thanks again for all your help, I just wish I could a more direct answer on exactly what MFG and model I should be buying.
 
Ok heres a little candy for you I will share my secret place to get 600 watt switchable digital ballast. Maryland Hydroponics they sell the 600 watt digital dual ballast the mh600 for $119 here then grab an enhanced spectrum 600watt bulb 95000 lumnes on ebay new for $22 and then get a sunleaves lightwave reflector for $29.99 and there you go.My 2 600 watt lights with no glass or cool tube raise temps about 8-12 degrees in a 12 hour period
 
Yeah, I remember your setup, 2600 watts of HID lighting and only getting what - 0.6g per watt of lighting? I'm getting more than that from my fluorescents, so your advice isn't really worth listening to is it?

It's no wonder you're getting such a poor return from such high wattage lighting - you're having to use those shitty cool tubes to control the heat being generated by them in such a small space and of course anyone with half a braincell knows how shitty cool tubes are in terms of their light spread - no wonder you're having to use so many watts of light.

Many people with far less wattage than you are getting far better yield returns, and you honestly expect people to follow your example?

You rock, I am going to place an order tonight...

I still can not decide on 600w or 400w, I am planning on growing 3-4 plants...
 
Yeah....I only get rouglhy .06 grams a watt... 1100-1200 grams per 8 weeks. And you? You get what..an ounce? Woohoo.

But it was all done with a 45 watt CFL...1 grqm per watt...right?
Big fuckin deal. Ask folks here if they'd rather have 2-5 pounds or a few ounces and see what they say...OK?

Oh....and I also told ya I'm medical/can't get to my room as much as I'd like to/on a daily basis due to ***chronic back pain***...(much like you are to many folks here..it's 24/7) I wouldn't expect ya to understand tho..understanding just doesn't seem to be in your nature...

FWIW...I'm in the process of building a new room. I'm sure it'll be CRAP compared to whatever you have goin...so I won't bore ya with it.
My yields will probably suck in there also as I'm not doing CFL.... oh wahhhh.

but enough of me...let's see more of *your* set up. Show our friend shady how it's done/how to fill that sppace with CFL buds....

No one else here *obviously* knows as much as you do, babyblo.

Shady...SORRY for that. My advice stands..and I can see from your pics that you have it UNDER CONTROL. VERY nice additions/electric. Get yer light...set up yer ventilation..and let that thing RUN for a cycle...watching the temps. I will tell you that I'm not sure those fans will be strong enough ..they're really "boosters" for other fans...but maybe.

Anyway... Get it all dialed...THEN plant the seeds...etc. It'll take off like mad.

PM me if you need anything else.
