You need to choose your favorite of those three and kill the other two or at least attempt to transplant. I know it's going to be hard to choose, but those three will NOT all survive to harvest that close together and if even just two of them survive they'll both be competing with each other and definitely harm your overall yield.

Oh and if you go with HPS light id get a Cool tube and run a intake line threw that and out. That light is going to be your heat factor. you also want ventilation for fresh air intake.





Cool tubes are the worst.  Just buy a standard sealed reflector and you'll get twice as much light efficiency for your plants and only a very slight decrease in your cooling power.

Also, if he's running a 6" or even a 4" vortex in a 3' x 3' tent then he can definitely save his money and just use passive intake. All tents will have flaps at the bottom you can open and they will more than do the trick for fresh air.

An exhaust would go filter in room duct to hood/tube duct to fan.





The most efficient way (in terms of minimizing chances of odor leaks) is Filter --> Fan --> Ducting --> Reflector --> Ducting outside.  This way if there are any leaks it ends up blowing filtered air back INTO the room due to the positive pressure in the ducting. With your setup it'll be pulling unfiltered air from the room into the ducting before being exhausted outside because you're pulling negative pressure in the duct.

I'm not sure you can :shrug:

In your post you said you just transplanted. Does that mean they were separate and you just put them together like that? If so then it should be easy. If they grew like that from seed then I'm not so optimistic....

huh, all that is shinny doesn't reflect light reflect light efficiently. I wonder how well these work. I guess in a thought experiment your just reperising them while keeping them doing what they where desinged for (if that makes seince) but wouldn't a gallon of paint be easier/cheaper. unless of course you need something you could take down in a hurry leaving no evidence.




Yea flat white paint has a 60-70% reflectivity. as where that shit... doesn't reflect much of anything and what light it does reflect is all over the place.





Actually shiny DOES mean it's reflecting light. That's literally the text book definition of something being shiny.  Things that aren't shiny can still reflect (ie, flat white paint actually has a reflectivity efficiency of >90%) but basically all that is silver will reflect a vast majority of the light. 

Additionally, the scattered reflection is ideal and preferred. Granted you'll get a much better (read; even) diffusion from matte white than from a specular silver like that, but it's better than nothing.

Calm down homie.  It's not an achievement to correct people, but as a MODERATOR (you may have noticed that) it's my JOB to make sure that we're presenting information with the highest level of accuracy possible.
