Hi dude You say the Cool-Tube allows you to run open bulb style, Do you mean like I have it at the moment?,,,, Is it possible to run the above air cooled hood in the same manner? .. Open ended? In theory it should work the same only in the hood the lamp is below the 2 air-duct holes but both units are enclosed so the air's passing through, I would have thought would cool the lamp just as efficiantly, maybe I am wrong - Thoughts please
Yeah I got the SCROG in there, I thought it would be fun to do and also seems like a good way to produce way more buds,.. In my old unit I had to ladies under LED and CFL lighting and got 7.5oZ I wonder now I've increased the size of the unit, changed to HID lighting and added a SCROG whether I'll pull the same weight upon harvest or how much more... The joy of waiting to weigh The 45oC SCROG did and still does seem like a good idea, not so good in my setup but.. it would work.. but would require 2 HID lights staged at different heights to give out an equal coverage of light. Lastly I would love to get busy sewing my seeds asap, I just wanna finish the project now! lol But need to inject a few more quid to finish it off and make it all worth while, I say 1 Month and counting and should be good to go - STELTHY 
The 2 light Cool-Tube would be good and easier, I would only be running either 2X 250W = 500W bulbs, or 2X 400W = 800W bulbs, in there running 2 600's would be over kill in this unit infact 2X 400 would probably be over kill, But saying that If I doubled up the tube lamps I would need a new 250W ballast and need to drop from a maximum of 600W to 500W But if I change the hood (less money) + better light coverage I can keep to than plan of testing out both a 250W, 400W and a 600W grow and because the reflector hood would be more central the light coverage should be more even
Temps arent too bad at the moment, sure when the 600's in it goes up but I havent gotten around to modifying my loft (room above - outside) to pull in fresh cold air yet, but since I have 2 grows (250W and 400W) to do 1st its not important to do just yet, I see your point about light bleaching though... I may look into adding a tinted Perspex screen when doing the 600, to take the edge of of the light but still keep it above the potential lumen output of a 500W setup,...Just and idea (and needs looking into 1st) Ultimatley least wattage/ least power and biggest yield will win for my future harvest but I have a minimum of the experiments to do 1st 250,400 and 600 and what ever comes out shining I will keep as the prefered power/wattage for my future harvest's etc - STELTHY

Hey man, yea Open bulb is pretty much like you already got it except your tube has a small reflector on top instead of all clear tube. a hood would make for better light efficiency because you wont be losing any lumens going sideways or up instead of all down to the plants. I would run a hood with the glass in it and run the ducting to it like done on your tube. I was thinking for the 45 scrog to angle the light 45 with the screen somehow...With the HID and scrog you will definately make bigger yield my friend.....Hi dude You say the Cool-Tube allows you to run open bulb style, Do you mean like I have it at the moment?,,,, Is it possible to run the above air cooled hood in the same manner? ..

Hey Stealthy, which hood is that?? because I have a simalar one called the blockbuster, it covers a 4x4 area very well and I love it.
Or this one? ...I like cooltubes but if these bad boys deliver more light per foot take up less space and still allow a decent air cooled flow to pass over the lamp this maybe a better option, If I do choose to go down this route I am thinking I will most likely go for this 2nd one due to its angled reflective sides and the fact that i can only position it one way around. What do you think ? - STELTHY
i also got a similar one called an aerowing, i upgraded from the cool tube, never looked back. i love the upgrade, the light spread is perfect in my 4x4 also
I am not 100% sure which hood this one is, But its most likely the one I'll upgrade to in the near future
I ve heard good things about this one - STELTHY
Again... Most likely I will upgrade to one of thesei also got a similar one called an aerowing, i upgraded from the cool tube, never looked back. i love the upgrade, the light spread is perfect in my 4x4 also

!!! I wont bother with a sliding door over the CCTV - Because I am going to cover it with 2 layers of Perspex and tint the outer piece with Limo Black Tint to keep it Stealth! It will also help to keep the top section quieter I am working on a way to send a live feed to my laptop..Or even my HTC Android Phone that would be really nice... Most importantly I want to finish the unit soon but I mean subtle upgrades are always do-able in the future! - STELTHY 
1st of all HI
lol A random thing to post in my thread but hey! lol, I'll help you (This once) Ok Yes the design would work BUT.... you'll need an in line fan that moves air fast and is quiet a SYSTEMAIR in-line fan should do the job @ 5 or 6" (if you plan on using HID lighting ie MH/HPS for the size of the setup I would be more inclined to tell you to use either a 250w Envirolite/Envirogrow light or A 300w Envirolite (CFL) since CFL dont put out anywhere near the same ammount of heat a HID and you could getaway with using a 4/5" low powered in-line fan... much quieter and it will cool the CFLs nicely! ......With a bit of adjusting this would work fine but from experience double the height of the unit, when the plants get bigger and fill out there is not as much air movement in the grow space and the plants WILL SUFFER expecially if its your 1st go and your learning...Hope this helps dude - STELTHY Thank you Stelthy for a well thought out responce. I put my little drawing in your thread because I have read most of this thread (now up to page 39) and your knowledge is apparent, and your ability to make an amazing grow cab is obvious! I love your idea of doubling the height.., so that I can make bigger bushes and get a lot more bud from it. I am thinking that this cab could be nearly any size to eh? not just 2*3, but maybe even 3*4 and put in 4 plants instead of 2? or would you say 5 or even 6 plants in that size of cab? Id think it would be easier to go with 2 light tubes and have 2*250 watt or 2*400 watt bulbs in there? Then to keep the temp down I just need to keep adding more PC fans until the temp stays consistently 26C right? I think for my first cab I want to go as simple as possible so that I dont kill the plants. I will def go with soil. Thank you so much for your help there stelthy!1st of all HI
You will need an air intake fan, and an air filtered outtake, so 2x CPU fans will do...1 at the bottom left drawing air in and 1 right at the top blowing air out, wire them together and attach to a timer, do this for your light too (on a seperate timer) and have both timers set the same. Ie Lights on.. Fans on..........Lights off.. Fans off! Job done whilst in veg smell wont be much of an issue but give it just over a month and the smell will get stronger, be advised its a good idea if not essential to get a carbon filter for your outtake fan as this will keep you room smelling normal.
The moving of the shelf seems like a good idea, just remember if you hold your hand under the cooltube n it feels hot....too hot then the plants wont like it so a bigger fan maybe needed! BUT if its barely warm and the ambient temp of the room id 26oC there abouts the girls will be loving it! 21oC min 28oC Max is what I go by and as close to 26oC as possible the rest of the time
Plants need fresh air, it helps them grow and bringing in fresh and blowing out old also prevents mould and other nasty thing that can pop up n piss you off in your grow room! So although you light tube would be seperate...you WILL still need a seperate air in and out to keep your girls healthy, Obviousley in veg it 18/6 - 18 Hours of light 6 Hours of darkness (complete darkness) and in flower 12/12 - 12 hours of light 12 hours of complete darkness! And you need to keep the soil (if your using soil ) - DAMP not waterlogged and not bone dry, you'll need to PH balance your water you give them PISS YELLOW On the PH TEST is the preffered test colour about 6 - 6.5 then low quantities of nuitrients that are intended for use in soil grows.. (NOT MIRICAL GROW!!!) lol a grow shop/site can assist you more on this
In this setup I would leave CO2 alone...its do-able but for the effort/expense its not worth it good nuits..good light and good air will provale here Thing to remember is plant can grow big.... If you put them into flower early (6-8") they'll be fine in that sized setup if you wait till they are 21"+ then they'll get pretty big ie sometimes 40 - 50"+ and bigger than that too, So my friend
But G-HETTO STYLEE lol....ah man it shows money is there to be made and once I've finished this project I will start my own on-line business selling my work efforts, either my own custom cabs or 1's made to order, You gotta check 'em out But my Cabs will well n truely beat the crap out of his [video=youtube;Z9fTIp9sTkM]http://www.youtube.com/watch?v=Z9fTIp9sTkM&feature=player_embedded[/video]
