Can I add 600w hps in with 2 led

Can I add a hps 600w in with my leds?

I think temps are all you'd need to worry about.

Will an extraction fan and duct be enough and let it go into another room if so how high power fan for one 600w hps mate ?

Yup you'll be grand u gonna run a hood?

I was thinking of something like this but what size extracter would I need or what power ? My heat is up and down as it is because I use a fan heater to get it to 25° c . It is automatic so comes on and off every 5 to ten mins it does keep it around 25 though but a hps is obviously going to upset things ?

a open hood 600 hps . this is some serious heat . about the same amount of heat as 6 of your led lights . you need to get a hood like this and hook a fan to it blow air into it . https://hydrobuilder.com/8-cool-tube-reflector-w-wings.html dont buy the one i posted shop around for lower price .

Thanks mate do I get an extracter to pull air from it ar a fan to blow air into it

And does this one look any good mate

I use a 600w hps and 2 cheapass LEDs which work great together. Buds are dense; rock hard and super sticky. I use my leds as targeted side lighting & the hps as the main; works very well to expand the footprint. I can easily bloom 8 plants at a time.
You will need a good ducted exhaust fan to pull off the heat unless you plan to run an a/c. It's best to get an inline fan that is slightly more powerful than you need & use a manual speed control or thermostat to adjust temps up or down as needed.
Calculate the sq. footage of your grow area length x width x height to figure out how big a fan you will need. You want to replace the entire mass of available air in your flower area every 2 mins. Inline fans are rated for cubic ft or cm per min... not smart enough to figure out how to convert this all to metrics but you get the idea.

Thank you rich I get most of that , would it be possible for me to get around 2 0z per plant with 600w hps 600w viper led and 450 w viper led ? And also the fan that you advised me on , does it have to blower air into the light or pull air out from it .

Cooltubes are ok but I think a good angled hood distributes the light better. Depends upon your space: cooltubes are good for tight squeezes in small tents but if you got some space to light get a wider hood. My bloom room is 10'x5'x7' Here's what I use:

Absolutely; I am using slightly less wattage and I pull an avg of 2-3 oz of premium cola bud per plant plus lower material & trims for making concentrate or medibles. Inline fans pull the air from the hood to an external exhaust.

You've been a great help rich thank you

push air into the light and it blows out . here http://encinitashydro.com/wp-content/uploads/2015/02/053.jpg i suggest the 8 inch reflector not 6 . major cooling difference . the cool tube posted you could put it in the middle of the room and your 600 would cover about 3.5 foot square and your led would be on the sides of the tube. a square reflector is a great unit but it will shine the light very strong in one spot very intense and it will be hard to get a good coverage with the led lights . think about it a long and skinny tube will cast that light wide and its only 8 inches around . the flat reflector is 2 foot or so long shooting the light straight down . so the led will be on the sides but 2 foot away and in this case its hard to shine the led on the plants unless they are a angle and your wasting a lot of light . i own a lot of reflectors been through this lol .

looking at your picture that 600 watt hps tube will fit right in the middle of those 2 led and it would be perfect .

That's the plan mate exactly how you said it hope it works and thanks for the help I am going to expand the space from 2x6 approx what it is now to 3x6 so when I top them etc should be more space and hopefully all three lights should cover

Is that mylar or similar... not tin foil? Can ditch the mirrors, too many cheap alternatives are a lot better/effective

It's tin foil and one mirror is in there . I have been worrying about this plant which started drooping down heavily all of a sudden last night about 2 hours before lights off . And another one is semi doing it now

throw that mirror out ! with a hps light in there it will BURN your plants I guarantee it .

I will do today . I just seen a small bug crawling around the rim of one plan it was a light colour . Do you know what soloution I should get for that ?
