If you can't manage marking the centre of a sheet of aluminium, rolling it up, partly unrolling and bending a 90 along the centreline and drilling 2 holes in it to fit it to a cooltube- then you are excused. Otherwise, you're just a stoned slacker with more money than initiative.

About $AUD220. Too expensive to just buy with the intent of throwing away the lamp mount/socket.

i think imma get the cool star plus.

I have owned the cool star plus before...I was not a big fan of the dimpled aluminum. There were more hot spots then the pebble-finish of some other brands..

i thought the csp were new???

I bought mine "NW US" last summer...

mmm...i've never heard of it (the hotspot problem)

are we talking about the same one?

anywho thanks for the info!!!

Hey Al, I have been discussing an issue with a buddy of mine, and I thought you might give me some insight to this "issue"...Do you think running an exhaust fan the full 12 hours of "lights on" causes any type of co2 deficiencies? The thought is that with constant low pressure in the room "besides the time the intake fan kicks on" which is almost twice as much CFM as the intake, causes stagnet air some how...

Hey blunts, yeah I double checked to make sure we are on the same page, and yes for me, the cool star plus was abit of a let down due to some hot spots. I placed the problem on the "dimple" design, and taking to more of the pebble finish. The cool star works well on a light mover though..I like the idea of a straight tube to create less resistance to air flow, but I will stick with the cool sun for now.. Cleaning is much easier also...

Hey AL here is my set up. The only thing i left to do is set up the CO2 system in my flowering room. The pics with the plants in the small Homebox is my vegging room. I am vegging my mothers and hopefully they will be large enough to start taking clones from by the end of April. I will probably just flower some of smaller plants on the left and keep the larger one's on the right for mothers. Do you have any advice for my set up when i start flowering the clones ?

AL,

Did you ever mention how much more you were yielding by installing the cool-tubes?

The AAWs use a dimple finish, squillions of perhaps 1mm dia dimples, a round headed punch of some sort used to make the dimples. No hotspots.

For a reflection to focus on a point and cause a hotspot, the reflector would have to be of a size large enough to collect sufficient light energy to do some damage if focused on a single point and also be of a convex shape to facilitate focus.

I would worry more about the 'pebble' finish I have seen in other reflectors, but in truth, I'm concerned about neither. This is something that would be weeded out in very basic performance tests in prototyping at the manufacturer. Few commercially made horticultural lighting products are all that slapdash anymore, but there's still some old designs being made that really should die (i.e. Euro hoods, china hats) because of inherent design flaws.

In the early days of the automobile, pundits theorised that if one drove faster than forty-five miles per hour, driver and passengers would be suffocated as the air would be sucked out of the lungs.

Same nutty theory.

Unless your exhaust blower is an Ingersoll-Rand screw-type air compressor capable of 6000CFM which drops your air pressure to around -200psi, stop worrying.

Make sure it is fully operable and tested before you need it. Assure it will maintain 24-26C @ 30-50%RH by running it with no plants, just a towel dipping in a bucket of water, placed under the light. Make sure that all electrics are off the floor and protected from wet. Check for light leaks, make sure your op is inaudible where passersby might hear it. Get your scent controls ready as needed.

Too soon to tell. Haven't gotten a batch out yet that has been in the room only since the cooltubes were installed. However, the next batch to come out has been under the cooltubes for the last 6 weeks- and it's looking really good.

tell how u use 4 trays, i see the method but dnt understand how are u lighting all areas, so im assuming you have 4 trays and they all have hps 12/12, please help me with how do use light i see the rotation but i still dnt see how its poppin out every 2 weeks??
