new grow room 250w or 400w hps?

I highly recommend you get all the info online and PLACE YOUR ORDER ON THE PHONE..!!!!

I can't stress ORDERING ON THE PHONE enough...

Every time I ordered from them ON THE PHONE, I was given an even better deal than online...

PLUS.. if you have a problem... you can deal with the EXACT PERSON THAT SERVED YOU BEFORE...

but that's just my experience...:razz:

I have dealt with HTG...

Other than that...:eyesmoke: it's pretty much your choice...

I'm running a 400 watt hps in a 6" cooltube. My cabinet is located in the garage and so far this summer I have been battling heat issues daily. I have to run the light at night due to the high daytime temps. My flower room dimensions are 3' x 2.5'. The flower room is Cooled by 2 x 4” axial intake fans, 2 x mini fans for circulation, 1 x 465 CFM exhaust fan w/ carbon sock. I expect that I will have an amazing yield come harvest time but it hasn't come without the constant burden of heat buildup. So I guess my point is, I have a shit load of air circulation but still have heat issues. Here's a link to my newly posted first grow if your interested. :peace: OUT! https://www.rollitup.org/indoor-growing/220054-first-grow-400-watt-hps.html

May I ask what the ambient temperature in the garage is?

I mean.. what temperature is the air in your intake?

A properly ventilated tent/cab usually runs about 5F higher that the room it sits in... and MOST of that is radiant heat...

It runs almost exactly 10 degrees hotter than ambient when the light is on. It runs about 5 degrees cooler when the light is off. To answer your question the garage ranges from about 65-80 degrees between 10pm and 10am which is when the light is on. Do you have any suggestions of how I could ventilate it better?:confused:
 
yeah i like to order over the phone, i hate putting in the credit card through the internet. even though i'm close, shipping is still like 20 bucks.

man i hope i dont have the same heat issues as you do jrp, i have way less ventilation than you do. is your ballast outside your grow room?
 
I have no idea how your set up is ventilated...

But if you are exchanging the air properly, it should be closer to ambient...

What makes it hotter inside during lights off??? it should be the same as outside...

And I am sure you know.... but even if you only have 1 CFL... if your intake is at 80F.. it will never be cool in there...

I had a 600 HPS in a 20"x36"x54" tent inside of my room with no issues... I just kept the room at 70F...;-)
 
here's some pics of my girls

I wish I had the option to keep the cabinet inside the house but I don't. The ballast is inside the cabinet but in a different section than the flower room. I use Sun System digital ballast and cooltube. I think you misread, the cabinet is 5 degrees COOLER than the garage when the light is off. I'm running 2 105 CFM axial fans for intake and a 465 CFM squirrel cage fan for exhaust but yes I know the cabinet can only be as cool as the air being circulated so I'm just going to have to tough it out through the rest of the summer. With that being said though I still think the cabinet would heat up 10 degrees hotter than ambient temp even if I kept it in a room that was only 50 degrees. How can I get it down 5 degrees?
 
ok... my bad... I must have mis-read...

you say you have a cooltube... it should have it's own fan... and the air for the light should never mix with the op's air...

then I would use every last cfm you have available for exhaust... believe me, if you exhaust it, more air WILL COME IN...:lol:

Here this is the best way I know to describe how to vent an op, ANY OP, properly...

Is this how you have it?

as a note... the intake blower is optional on 99% of the cases...:razz:


​
 
and I know that you have them and that you should use them... but AXIAL fans have no place in your op... other than the circulating fans...

Get a 4" centrifugal fan FOR YOU LIGHT... set it up like the drawing shows... and you will see a drop in temps...:razz:

The axial fans are only for air intake. I have a duct booster hooked up to my cooltube. The cooltube is definitely not hot to the touch, the glass is just barely warm so it leads me to believe that I have a heat buildup problem but I don't really understand why.

Here's a crude drawing of my flower room. I had to resize it to be able to post it so sorry if it's too small to see.

Well, the only differences I see in what you are doing is using the axial/duct booster fans and that "box" on top...

I can imagine that it adds considerable drag to the airflow...

And I would bet that you would get more intake if you removed that fans and had proper sized holes...
