I can see how 24/0 is better than 18/6, but my theory is a bit complicated...i'll explain. Photosynthesis creates food energy, but Respiration turns the food energy into energy to grow and for other life processes. Photosynthesis, at ideal temperatures (60-86F for pot), creates more food energy...

Answering the following questions will help us growers stop wasting our time finding the best bulb to use. This will help us find what bulbs not to use with certain ballasts and what bulbs just aren't worth it. 1. What ballast do you use and how old is it? 2. What bulbs have you used and...

I will be doing several experiments for indoor growing to see what brands swear by their advertisements and which ones should be repped more. This one will be on fans. I will be doing it on 6" fans since they seem to be the most popular. I will be tesing the follwing: can-fan 6" HO...

Found this cool light distance chart from www.vertigrowsystems.com. Thought people would find it useful. its measured in foot-candles which is the same thing as lumens per square foot. It proves that the equation posted everywhere isn't correct at all. its not (distance from bulb)^2. Its...

I was doing some research on plasma lighting and got this sweet experiment they did when comparing 10 different lighting options. One thing i noticed was that the 600w HPS was just as good as a 600w HPS/400w MH combo. And a 1000w HPS was hands down better basically because it had a lot more...

I just found this new company that makes vertical growing trays, so you can easily make your own vertical growing system. I did the calcs and you can get 18 plants spaced 6" apart and 27 plants spaced 4". If you did 6 levels with 27-12" plants a level, I'm sure you can pull off 5 pounds.(if you...

What is the tallest plant i can grow with a 600w light, so that the plant will bud all the way to the bottom. I have used a 400w and those suckers can only yield decent sized buds on the top two feet.

Because there is alot of arguments between hps and fluorescent lighting for microgrowing I have decided to conduct an experiment to see which one is better. I will compare several different qualities of the plant; look, taste, smell, yield, high, and overall. I am doing three 16.5" x 24"...

Do enhanced spectrum bulbs make a difference in the yield or bud quality?

I am thinking:idea: of having 2 2x4 tray lined up lengthwise and having a light mover run a single reflector across the whole canopy. The reflector will have 1 standard 250w hps(28000lumens) and 1 standard 250w watt mh(23000lumens) to yield huge high quality buds. This air cooled reflector will...

Has anyone used the xtreme LED 130w Grow light by CAP? I cant seem to find any proof, post, or grow journal that it works as the advertisements say about it.

Should I ventilate a grow room if i use a co2 generator, air conditioner, and dehumidifier?

I found these great grow cfls on the net for cheap. 125w 6500k CFL I'm thinking of using either the 125w or 200w cfl in a vertical grow, sog method and they can get extremely close to the light and heat wont be a problem. I basically want to set it up like heath robinson's vertical grow...

I want to get some info on some led grows. what led lights not to get. what led lights to get. the yield you get from using an led. Any information and pictures on led growing would be awesome.:-P

I'm looking to set my grow room to an optimal CO2 ppm. What ppm do you set your grow room to and could you tell me the difference in yield when you didn't have one?

I've been reading up on how increasing the co2 creates a tremendous increase in yield. Is there an optimal ppm for the amount of co2 in your room? What ppm do you set your room at and can you state the increase of yield you got from adding a co2 generator to your grow room?
