Hello Everybody,

I am getting a 125mm Cool Tube but was wondering if it is ok to use with a 600w HPS. The fan I have is a S&P TD160, only a small space, so heat will be a problem.

Anyone who's using a 125mm c/tube, what do you think has it helped.

Cheers Everyone.

they are the dogs balls m8 could not grow with out them! here are 2 x 600watt in a room in the loft the box is 1m x 2m x 1.3m high. i use a 6" ruck fan to pull air over the bulb
p.s there are doors on that box that close the temperature is spot on 75f it can get up to 100f in hot weather,but if run at night its around 85

Sure it helps mate,if u take air from outside to go trough cool tube and let it go out without carbon filter it works great i use this type of vent. for cool tube its ck 100 ,and 16cm rkv for whole space 1.6kw on 2m x 1m and it works ok,hope it helps(btw my tubes are 125 to)
-on summer it gets a bit hot 32c at peak then i kick one lamp out...

no prob.man i pull it from outside cuz its could air at night but with one 600w think u will have no prob.but u better have a bit stronger airflow than weaker

Cheers Nuts and HK,

Nuts, running 2 600s in that space ..my heat worries are no longer.!!! Good looking grow space, how much you yielding.?

HK, sucking air from outside over the bulb, I like it, will have to re-think me space but cool.

Thanks for quick replies guys Appreciate it.

not as much as i used to when i was doing SOG that space would pull around 1300/1400/1500grams but Paranoia has set in and dont do it that way anymore ill be happy with 30oz from those 3 plants. if i had 6 plants in there it would be around a kg. the plants in there are about 3 weeks flower
