150w HPS Club: Inspirational Resource

Anyone have a link to a DIY cooltube for the econolight hps + ballast?

I am just growing 2 plants in my closet setup (14'' x 21'' x 42''+), do I even need a cool tube for this setup if I have intake and outtake fans?

Thanks for the help guys
 
I need cheap mylar where can i get about ten feet or so of it cheap???? Help please.....rep for answers thanks
 
Thanks a lot for that link smokey, and would people here suggest a cool tube for my setup? Any input from the veteran 150w club peeps would be great hah
 
and you dont need a cool tube for a 150 at least i dont for my 2.... and can get them 6 inches away..... i was told 26 inches and 6 is no burn perfect but good luck with the whole grow
 
cooker - cant help ya bro, i dont use mylar..

letsdothis - in a cab that size you shouldnt need a cool tube, but it would have its benefits in a cab with limited height esp if you're growing a strong sativa dom plant, as it could stretch alot, and using a cool tube will allow you to let your plants grow closer to the light without burning.
150w hps dont really throw out too much heat, mine are around 79degrees @ 7" away from bulb..and some of that is trapped heat under the reflector.
If you currently have the heating on, your cab temps could be noticably higher for obvious reasons, but a good 4" fan installed in the cab as an Exhaust will pull the heat straight out.
thats what i use and my temps are steady 75-77* during summer + winter.
 
Thanks for the tips frosty and yeah I'll have 2 4'' fans (1 each for intake/outtake). Also you mentioned that yours has a reflector, would you suggest getting one of those no matter what to make light available? I'll have white reflective siding to my growbox/tent and I'm growing afghan kush-indica in case that matters.

Thanks man
 
Yeah i use a dimpled batwing reflector..Using a reflector makes use of the light that would otherwise be lighting up the top of your cab and not your plants...and we all kno every lil bit of light counts, so why waste it?
white reflective for the sides is good :)

A bulb reflector is not necessary for colloseum/barrel grow styles, or those where the HPS bulbs are hung vertically

just put a fan on the bulb. my light is with in 2in of the top. but that's cuz i'm out of space.lol
 
Does anyone have a link to where I can either purchase a cheap reflector or make an easy DIY one? I don't have many tools to work with so the easier the better.

I've searched the whole forum and this seems like one of my options, but how would it perform?: https://www.rollitup.org/do-yourself/109235-building-cheap-light-reflector.html

[EDIT]: Might be important to note that I am working with limited space (14'' x 21'' x 42''+), since some reflectors might be too big for this space

Thanks guys
 
Yeah at first I think I am just going to try and use a reflector w/o a cooltube and see how the temps are, but thanks for the link.

Still debating on whether to make the DIY reflector made from mylar/posterboard or something else..
 
here's another link to a batwing reflector. shows a cfl in the thread, but all you'd need is a ballast to use a 150 watt hps.

or you might even consider this. compact hps, i've got one myself. it's about 16" long x 9" wide x 5" high. not bad for $70. i'm not sure on this, but i'm sure that having the ballast in the reflector doesn't help at all with controlling temps. could always turn it into a remote ballast.

Perfect, looks like I'll make one of those batwing reflectors then, I like the intuition behind it; more light for the plants :)

Thanks for the help bc
