That exact info really isn't in the manual.. For a 3 x 3 400w HID equivalent.. I've guessed at 125w of Blue 425nm and 440nm. Aprox 300w of Red 660nm, and you can also use some Red 630nm (because it's cheaper) and for the Far Red aprox 75w.. That's my guess for a 24hr 3 x 3 flowering area.. I know it looks like 500w total, but under the 24hr flowering method that wattage will actually use less then most 12/12 400w HPS setups.. It's kind of tricky to explain, but if you got an understanding on the timing for a 24hr flower. Then it's relatively easy to run the numbers.

Starting out 12/12 or 10/14 depending on your strain, will be easer for you as a beginner.. But you still will have to have the timing correct between the three spectrums if your going try 24hr flowering.... Kind of tricky at the present time..

The easiest thing to do and get great results is Raubers substitution method.. Blue led's and Red led's only.. The blue led's stay on for whatever duration of 'on time' your using i.e. 18/6 or even 12/12 and the red 660nm cycles on and off in 1/2 hour cycles during the same 'on time' wile the blue led's are on.. No far red in this mix.. Just Red led's and Blue led's... With this setup you use the same amount of wattage between both colors.. Example 150w Blue led's and 150w Red led's... Or you could run a MH and cycle the 660 on and off every 1/2 hour wile your MH is on.. Same thing..

I have not tried any of these timing sequences.. So I don't know..

Sal and Rauber at TP are coming out with a timer.. I'm just waiting to buy one myself..
Dogznova Reviewed by Dogznova on . Selling 600w to go LED, need help with PAD/rauber technique I'm getting rid of my 600w HPS because I'm moving into a studio apartment and don't want super high electricity bills. Normally I can yield about .6-.7g/w. Because of the high cost of LED's I know I'm going to have to seriously downsize in terms of wattage so I want to maximize my yield potentials by manipulating the photoperiods. I'm going to be constructing a few of my own panels and was looking for input as to how I could successfully make a veg chamber and a flowering chamber both using the Rating: 5
