Ventilation with Wing Reflector Question

I’m going to start my first grow real soon and needed some help with ventilation in my grow room.

I’m doing DWC. I will be doing 4 plants. I have a 600 watt MH and HPS with a wing reflector. The MH is for Veg and the HPS is for flowering. I have I made my own room in a basement apartment. I have a 6.5(L)x7(W)x6.5(H) room. I will also have a fan or two inside the room.

I know plants need constant air exchange and I know it helps with the humidity and heat of the room. I just wanted to know if could I still some how use the inline fan and ducting to take out the warm air and the other one to bring in more air?

I tried looking online but nobody is really talking about air exchange with wing reflectors much.

Can someone please help me or explain to me if this is still possible?

No I’m not going to get a vented hood or at least not yet. I already have this light so I’m going to use it.

I’m really new at this so anything would help.

Ventilation 101

Read it,learn it,live it,love it.

And remember that 600w is probably best suited for a 4x4 footprint so keep that in mind, you have a lot of room to work with mate.

Read the 101, but to try and answer your question...

With hat set up I would personally get some kind of extraction kit for getting rid of your heat and then use some passive intakes for new air.
Them lights get extremely hot and its also not about just expelling the heat. Like you said you already know how important air exchange is.

I would also maybe get more lights as the person above me said you have a lot of room to play with....this also being said you heat issues should be less than the average person using the same lights as they would have a smaller set up

Pretty much what hiddenkoncept had to say except:
I don't think you need more light, you simply need to reduce the area of your growroom
4 x4 is a good size for 600w AND a perfectly adequate size for 4 plants.
(I grow 9 plants in a 4 x 4).
You could use mylar curtains to partition the area down into a more appropriate size
(Unless you're planning on raising some monster sized Sativas any more than 16 square feet is inefficient for your lighting).

I also agree that passive in-take does the job fine
and using fans to bring air in is usually unnecessary (unless you have a sealed space for CO2 or something).

Here's the equation you need for working out the size of fan needed.

First-convert feet to metres
4 x 4 x 6ft = 1.2 x 1.2 x 2.0m
then
1.2 x 1.2 x 2,0 = 2.88m3 (metres cubed)
2.88 x 1,25 = 3.6m3 (this adds a 25% margin for error - better to be safe than sorry).
3.6m3 is the amount of air that needs exchanging every minute
3.6 x 60 = 216 m3/h 216 metres cubed per hour is the minimum fan capacity you would need for this space.

BUT taking away heat is another objective
for this reason I use a 6"RUCK and a $10 dimmer switch (cheap fan speed controller).

Here's a link to the RvK In-Line Duct Fan airflow rates list:

I can vouch for that website, use them all the time and have great customer service.
The set up I'm building is
H 2.5m
L 1.8m
L/D 1m
Odd sizes I know but its the space I have to work with.
I have some nice 1200w LED grow lights that really do not produce that much heat and have 4 in built fans for cooling. I have a 5" ksa aucostic fan for extraction and 2 clip on table fans fore moving air...Add this to the fact I live in england and my heat issues are quite the opposite, had to buy a grow heater with built in thermostat to keep my temps at the right level.
I have been in your shoes (kinda)and fully suggest a test run to check your heat,airflow etc until you get it as dialed in as possible.

Really helped me in 3 ways
1) get everything dialed in
2) have learnt so much more in past few weeks
3) just managed to get a move so if I had not done a test run...I would be halfway through veg by now and have no chance of a house swap haha

Thank you all for the help I’m going to probably just add more lights and just put more plants since I have more space to work with. I will probably also use a passive intake.
