All fluorescent lamps require ballasts. Fluorescent ballasts send an initial jolt of electricity strong enough to arc from one end of the fluorescent tube to the other, anode to cathode, to excite the gases inside. The UV rays that result from these excited gases are turned into useable...

Thank you folks. I knew someone else had to have asked this before my crippled ass.

So quality of light versus quantity of light, I'm sure it's a delicate balance. If I was a plant attempting to grow indoors under artificial light I'm sure I'd be craving a quantity of light with properties that most closely imitate the natural seasonal sunlight that inherently triggers my...

See this is where my knowledge of lighting fails to help me answer a question like this. A 2700K lamp is going to be heavy in the red, orange and yellow light wavelengths and short on the blues and greens. Is that the preferred spectral distribution when you're in the flowering stage or do you...

Some other information about HID and fluorescent lighting that might help you. Average Rated Life: They determine the average rated life by sticking 100 lamps in a room under ideal conditions, meaning controlled ambient room temperature, not being jostled, etc. When half of the lamps burn out...

That is correct, there is nominal lumen loss of approximately 1000 lumens or 4.3% (23,500 versus 22,500) IF you are burning these types of lamps in a vertical orientation (base up). However, if you are burning these lamps in a horizontal orientation then there is no difference (20,500 versus...

I had to laugh because I've always wondered how the Topsy Turvy tomato planter would work. :confused:

I would also suggest getting your friends to help you contact a "dealer" they trust. For God's sakes don't just go down to the barrio asking random strangers where you can score some smoke, that's a sure way to get busted or rolled. I'm almost positive you already knew that, but just in case.

It looks like the local "Head Shop" chain in San Antonio is called Planet K. I recommend following timsatx1's advice and shopping at the Planet K nearest you to purchase a one hitter, small pipe or small bong. This will allow you to experiment in small controlled amounts to make sure you don't...

WooHoo!! My first post. I have only recently become interested in the cultivation side, but as someone who has worked for the last 15 years in commercial and industrial lighting I feel qualified to provide you with some information on the subject. As stated previously what you have is a coated...
