Got a journal? Pics?

The science on this is sound. Been going on for a few decades now. If you want to read more about the particular methods employed above, then check out this paper by Zwenger published last year. He has made it available for FREE (no $35 just to buy a study posted to a science journal here...

Moash is correct. Same reason SubCool uses the planting mix he does; different fertilizers have been shown to increase Anthocyanin production/expression, also - usually at the expense of that of Chlorophyll (production). The ratios are generally inversely proportional. Keep 'em green =...

What strain are you growing? Cat Piss? :) -TL

Here, READ THIS. Then read my above response. If you don't know your strain, a good rule of thumb is to train your plants to the screen in veg and flip to flowering when the screen's roughly 50% filled. All strains are different, once you've grown it you'll know how much that particular...

You should be ok with the 250W, just make sure you've got great airflow. And if they start burning once they're near the light, just stick a piece of tempered glass between them and the lights like I did. Works well. The one I got custom cut with nice round beveled edges for the system above...

^^^^^^^^^^^^^^^^^ Any particular reason you just posted the exact same thing in three different threads? Afraid no one's going to see your pics? ;) -TL

10" is not a whole lot of vertical space, merc... Anything over 250W will burn the hell out of your plants with your clearance, and a 250's still gonna be hot/too intense even with a cool tube. I used to run a 150W in a 2' x 3' x 3.3' (see attached), had good airflow, and still used a...

Excellent! What temperature are you using? I would note that some of the studies used a lens to spread the light over a large enough area to accommodate the seeds they were using, so perhaps a focused beam at a lower mW would have a similar effect. And if you're happy with your germination...

Thanks sg, not sure that's going to do much though. I'm assuming that was a red laser also? Most lasers in distance measuring tools are rated at less than 1mW, even for the ones that run a couple hundred bucks. The ones you'll find in laser pointers used in business tend to run 3-5mw, sometimes...

Interesting work, Mr. Ballz. I'm assuming the wavelength used was around 630nm or so; please let us know if you find out the actual stats of your particular model. Its benefits in germination with mj at least may prove valuable. I've seen some of the other studies but to date haven't witnessed...

I would add that all white LEDs are simply blue LEDs with a phosphor coating on them to change the output spectrum, similar to fluorescent lights (which are UV-->white/colors). You will always lose a certain % of the initial intensity in the conversion from one spectrum into another (in the case...

Nice pics there ewo. Growing issues from this time around aside, do you have a final yield # yet? Thanks, -TL
