Purple stem problem

[TurboNugs]

Been searching and lurking found some good scrog info...damn i think i veg'ed to long oh well....learning curve is a bitch:jointsmile:

Im also thinking of lowering my Cooltube a little bit more .....damn thing stays really cool.

Check how close you can get the back of your hand to the tube without discomfort. This is the approximate distance the light should be.

Well hell i could rest my hand directly on the glass for awhile...so i dropped them to about 3'' above highest point of canopy. Very Nice....i like the cool tube, but the footprint on it seems to be kinda small...and when i take the "attachment" reflector thing off the light is more spread out and less concentrated on the ladies. So im gonna go with my current plan and keep it close .

[Rusty Trichome]

Shoot. I just noticed...You're using four foot fluoro tubes, right? There's a huge difference between cool tubes and fluoro tubes. Cool tubes are clear, tube-shaped housings for HID bulbs with an airflow to remove much of the heat.

If you keep a fan on the plants, heat from the lights is rarely an issue for fluorescent tubes. The closer the better, but obviously keep an eye on the plants for burn spots or stress.

Light from fluorescent tubes are only effective within 4-6 inches, depending on wattage. Reflected light hits the reflector (or wall) and bounces back to the plant. If those two distances added together are greater than the maximum effective range, the reflected light isn't doing anything for the plant.
For instance...if the reflector is 1 inch from the bulb, but the reflector is 5 inches from the plant...you are at your (approximate) maximum distance away from the light. (5+1=6) The same goes for walls and Panda Film stuff.

But if the reflector keeps the light out of your eyes, then I guess it could be a benefit. :thumbsup:

For better results, you'll want lights with more 'oomph' for flowering.

Ok hold the phone, in this thread I'm having "problems" in my veg room with two plants(purple stem). That room has the tube fluorescent lights. I was asking about my flowering room lighting (Cool Tube 19"x6" with 600 eye hort hps and Lummatek switchable ballast. Light is cooled with a 430cfm inline) I should of been more specific.....so for the record im in two different rooms with completely different lighting.:thumbsup:

I cluttered my own thread LOL:jointsmile:

Rusty sorry to confuse!!!

[Rusty Trichome]

Difficult to keep track.

If you do keep the cool tube that close, make darned sure the inline fan is reliable.
Effective distance is what...4 feet? There is a point of diminishing returns and possible light bleaching, so keep you eyes peeled for damage.

[TurboNugs]

Light bleaching ? Some of the new top leaves are yellow/neon green surrounding the bud sites. Damn I'm a newb . I cant post pics yet.

[canniwhatsis]

Having the same issue as Rusty,... It's hard to track,.... which side is having the yellow new growth leaves?

[TurboNugs]

Im just going to make a new thread on the indoor growing area. I just got to question/concern happy and didn't give you guys all the info. Sorry fellas

[TurboNugs]

Ok made another thread to give you guys a better idea of what im trying to do.
