Stelthy's 600W Hps Project! (New-Cab)

stelthy-your taking out all of the air too quickly for your small cpu fan to give any beneficial intake. either you need to move that big self thermostatd fan so its bringing the fresh air in and get a fan to expel the stagnant air threw the cool tube and out the cab. or you need to leave the inline fan there and just buy a good intake fan to bring in lots of fresh cool air from your loft. if those ideas dont work looks like your either going to have to go back to a smaller ballast or buy a air conditioner of some sort either window or portable that can be placed in your room or loft to cool the intake air as much as possible. also they make the Lumatek digital ballasts that are dimmable which i am currently using, its a 600w ballast that can be dimmed to 400w and 360w, as well can be turned up from 600w to superlumens. according to my local hydro guy, superlumens only hirts the amount of time the bulb last, it doesnt change the spectrum but will increase heat for sure. haha shit you can even try turning the inline fan you got in there on its side so that the open end which is sucking from the side of the wall will be more open to the top of the cabinet and can possibly exhaust more air, the ducting will have a pretty good bend in it though. just some suggestions, hate seeing this stupid heat problem, almost beat me but i came out on top haha. hope this helps.

I am going to play around with my setup and update again in a few weeks have got so much to do now but I hope by my next entry I'll have a number of problems fixed, thanks for you input I am off to the hydro store to spend some big cash now ...wish me luck :) - STELTHY
 
If ya want to hang it use big elastic bands, I used ones from a camping shop there for tent pegs. this stoped a little vibration and noise

Cheers man, :) I 'am trying to keep noise minimal as well cos of nosey next door neighbours also the grow cupboard is in our bedroom and the loft is bog standard except wood panel flooring, so fan in the loft isnt out of the question but I would prefer to find another way :) however the way the system is setup at the moment when the cooltubes big 6" fan is sucking the air out it is also helping the CPU fan pull air in, and when attempting to open the cupboards doors there is a good vacume , I am honestly contemplating changing my giant cooltube for a smaller air-cooled hood and that should allow less of a bend on the left sides insulated ducting, if that still doesn't work then I'll replace the Prima-Klima 6" fan for a really hardcore fan .. I'll have to do some research though as to keep noise output to a minimal! and then finally if still no success then I'll temperally drop the 600 and use a 400 or 250 until next time when I go crazy and build my Ultra Cabinet from scratch, (with this one I really just wanted to get experience and knowledge under my belt..as with HPS etc Am still learning... its very different to CFLs which in all honesty I had mastered! Well as you can see there is a lot of tweeking to do but I will get there in the end, I am not too concerned about cost cos I know in the long run I can make it back :) but cooling these lamps is a fucker!! anyhow.. I bought some plastic number stickers and just mounted them in the 420 order on the Mylar.. the numbers had sticky backs so I just had to present them correctly, very nice and effective look I thought, still gotta plod on :) - STELTHY

Very cool man. Hang in there with the temps bro, it's gonna just take a lot of tweeking things to get it down. i'm havin similar issues in my tent right now with my 400W in my tent thats about twice the size of ur cab. got the fan on the light pullin air through and an ac in there and can't seem to keep it under 80oF. only runnin the light durring night time to help keep temps down. I used insulated ducting and it helps the temps and noise out a lot!! also adjusting the speed of your fan can also help with noise. my 2 cents. i'm sure you will figure somethin out bro. either way, it LOOKS great! haha
 
I was daydreaming earlier about the idea of like someone mentioned "starting from scratch" and building a whole new cab as big as my space will allow... and have it hide everything within it. It would be my ultimate grow cupboard the one I'd stick with for like forever... I could incorperate all the ideas Ive had for this one but with bigger space etc a lot more is possible. Its not to late to do it but I really need to go crazy measuring things up! I could still continue this thread since It will still be a 600 project...however I am still tempted to have a 250w and a 400w in there also.. so I may be as well to start a new thread.. Anyhow I am still pondering this idea as SO much work is needed but once done. . It will be the absolute best thing ever, am so tempted tell me what you think or am I just being mental - STELTHY

Hi dude, I've just been to B&Q and the wood is going to cost a fair bit... SO I'am going to stick with this unit for a bit and after completion play around with the positioning of the in line fan, then I may reduce the cool-tube length to allow better flow from the ducting and may add a 2nd in line fan to really vac out the heat. In the long run I will do a build from scratch but the cost is to much at the moment.. I need to do a few more grow's 1st :) If after my alterations the heat is still too high then I will down grade and use the 250 or 400 for now I looked into a AC unit but it uses 800w and frankly is going to put my leccy bill through the roof.. CFL's were so easy compared to this :( any how this is an experiment and I do want to get magazine (HIGH-TIMES + WEED-WORLD) quality bud plants so its persiverance... I know once its finished everything will look better and I am determined to get this working right and am going to give EINSTEIN a run for his money LOL :) "I will succeed"!!! Ok I'am fired up I ve had a beer and I am on a mission now!!! this will work! watch this space, cheer me on and wish me luck I WILL DO THIS !!! ... :) - STELTHY
 
A good way to cool your light is to pull cold air from the outside.....run your lights at night so you can take advantage of the cold air....this is how mine is setup outside--->ducting---->cool hood--->ducting----->inline fan---->ducting-----> back outside....keeps my 1000 pretty cool.......Stealthy if you use the same air from with in the cab to cool your light your cool tube won't work as intended,,,your blowing the hot air right back through the light ultimately defeating the whole purpose of a cool tube........

2nd get a second fan to pull air from your cab....hook up your filter to that fan for smell......that'll take care of smell.......and if heat still is a problem then you will have to get cold air from outside as well and pump it into your cab.........
 
You got this stelth u can still build another ultimate cab but I def want to see this working with some lil ladies in there. They would just be feeling all the love and hard work u put into building there sweet little home. I mean do u have anything currently growing? since you r keeping it will u use this thread for ur grow or start a new one? U might as well keep this going since u have so many watchin already. Whatever u decide I'll be along 4 the ride.

Ah here its is! :) this way the fan may ware out quicker but, BUT it should reduce the temps alot better, We'll see :) - STELTHY

This is basically how the tops going to look but this will all be covered later on, I've had a tough week stressing about this setup and have decided some good things, also some expensive things .. but hey :) I am getting there bit by bit :) - STELTHY

The light leeks aren't top priority at the moment, I will block them out but really wanna suss the temp. issue's first :) top fan and filter are looking nice though :) - STELTHY
 
Looking great, STELTHY. You could hang a curtain in front of your cab with how it sits in that recessed section of wall.
 
stelthy- that fan is going to make alot of noise sitting out there. not really stealth any more. but hopefully youll get around to covering it as you say and maybe that will help with the noise, not just the obvious sight of the fan haha. keep up the work and let us now when you get it all running and have a stable temp to report!
