should I use this cool tube or wing reflector?

[texastiger707]

I have a grow tent that is 24x24x60inches. I have a 250 watt hps light. I plan on growing 2 plants in a scrog style grow. I was wanting to know if this cool tube reflector be good for my size tent. Or just use the wing reflector with a 4inch carbon filter and inline fan for the heat? I am not worried about the smell of the plants. So would the cool tube reflector have enough light coverage for a scrog grow? And if I use the wing reflector would the 4inch carbon filter with the 4inch inline fan pull enough heat out of the tent? thanks for the replies.

Place exhaust at the top and your intake at the bottom and you should be ok.. That being said, if you run an air-cooled hood you can put the light a lot closer the plants= better results.

You're talking about my exact set-up almost to the tee...
I would rock the bat-wing reflector... they're cheaper and in my opinion they offer the same or better light coverage than a cool tube. But what you have pictured there is not a cool tube, it is an air cooled hood, there is a difference. I can tell you from personal experience, as long as you can keep the temps under control in the room that your tent is in, you should be more than fine with the bat-wing and carbon filter... and then you have a carbon filter just in case smell becomes an issue in the future. I keep the temps in the room my tent is in around high 60's with the lights ON and that keeps my tent in the low 70's.

ok thank you very much. so if I use the bat wing reflector. The 4inch carbon filter and 4inch inline fan should be good for the heat in that size tent?

 

[PersonalJesus]

Yup... I keep my room in the upper 60's when the lights are ON and the temps in my tent stay in the low 70's... and it works great for me cause I like to sleep in the cold anyway, not that upper 60's is all that cold. My only issue is that my wife is always bitchin'!

I run a 400w hid and use a 4" inline and 4" carbon filter. Temps are 60s-low 80's.


Here's mine.

ok thank you for the reply. I will be using just a simple bat wing reflector. So would a 4inch filter and inline fan still draw the heat out of my tent?

Of course it will. Just not as efficiently as Mr2shim's sealed setup. Most of the heat generated by this bulb is being immediately evacuated in this cool tube setup. The heat from batwings has to fill the tent and rise to the top for evacuation, much longer and less efficient system and more heat exposed to the top of your plant canopy. My 400 cool tube allows me to my hand right up to the glass with minimal heat transfer. This is important in short rooms with limited height clearance and when you are trying to get light penetration to the bottoms of your plant.

Look at how bushy these plants are. I can keep the 400 right up aginst the tops with no issue the entire grow.

so would you suggest that I get the cool hood that I have pictured for my grow tent? Thank you for your reply also.

 

[PersonalJesus]

I would also suggest you get an AIR-COOLED HOOD over a bat-wing, unless you're trying to save money... I thought you were asking about a cool tube and just posted the wrong picture.

I was just thinking the cool hood would put out better light coverage for a scrog grow than a cool tube would.

That one will do the job very well. Spend the money here, because later on sealed fixtures make a big difference in keeping heat under control and plant tops from getting scorched.

 

[PersonalJesus]

Yes... an AIR COOLED HOOD will definitely give you better coverage than a cool tube.

 

[prosperian]

Yes, your 24X24 will benefit from a hood vs long tube. My grow room was longer so I opted for a cool tube with a batwing, lol.

ok 1 more question if I may ask. So would I still need a inline fan for a cool hood or can I get by with a 6inch duct booster fan? something like this?

 

[prosperian]

When I did my research last year, in-line was the right choice for me. Most of the closet and tent growers I see are using in-line fans for exhaust purposes and like me, do not require any additional fans for intake. The in-line exhaust fans are so efficient they will create negative pressure in your closet. It's hard to open my door until the seals give a little. This keeps all the odors going into the carbon scrubber and not into the house.

I am not worried about odor. I was just curious if a duct booster fan would be enough for the air cooled hood?

Inline will cost more but is far more efficient. Just buy it now because a grow or two down the road you will want one anyway. Maybe get a larger cfm than you think you need and a speed controller. Overkill when starting up pays off most often.

Shiva and I think alike. Invest now in inline, use a speed controller to tweak it for your room.

ok thank you everyone for your replies.
