LPS lights produce 190LPW but do not grow plants well. par and ppfd are used by led makers to confuse ignorant buyers

sodium plasma lights are the closet to natural sunlight. when the price comes down they may be the next new fad. if anyone here wants to know the truth about LEDs they should read what nasa found after studying them for 30 years. the best they could come up with produced less antioxidants...

I think nasa knows a little more about led grow lights than folks here and most led makers follow their guidelines which is why most commercially made leds are multiband.if the data from the manufacturers is correct the efficiency of some of those cheap lights is around 35% which is not bad...

I hope the people responsible for these murders are prosecuted to the full extent of the law. maybe we need to bring back public executions for cases like this so that these people will understand the consequences of their actions.the internet is not anonymous. anyone posting on it could be...

we created devils and demons to avoid responsibility for our actions. it is easier to blame a devil than to accept our own evil and take responsibility for changing ourselfs. you do not find serial killers in the animal kingdom.only man kills for sport.

there are no demons or devils. there is enough evil in the hearts of men to explain all the evil in the world. this is the hell we must transcend

the small amount of alcohol in tinctures will not harm you and helps your body absorb cannibanoids much faster. and average dose for me contains 1/20 of an ounce of grain alcohol. I put it in my coffee in the evening and start to feel the effects almost immediately. with edibles it take about an...

probably not you need atleast 50 foot candles to stimulate any activity in you plants

I found that running 25 watts/SF in a 2ft by 2ft closet gave me the same yield as a 150 watt HPS. some test using only red leds shows saturation occurring at 1700ppf while others show that it occurs at 700ppf with natural sunlight. hope this helps

seems like LEO is always crossing the line with MMJ patients. in my state MMJ patient are allowed to grow under certain conditions. my local sheriff raided my home and tried to charge me with trafficking. the DA reduced the charge to growing without a license and then dropped the charge when I...

I used metal cloth hangers to make hooks with long shaft that I stick in the soil. as the branch grow I move these hooks toward the edge of the pot

perhaps because they were considered a separate nation.and controlled half this country at the time the 14th amendment was passed if you had an education you would know this. use of works like "libtards" gives proof of your ignorance and hatred.

I run 13% deep red (660nm peak) and it does seem to give a slight improvement in yield have you considered adding UVA leds to your array?.

that seems like a lot of money for a light that cover 4 sq/ft. most closet growers use HIDs or florescent. I have grown with HPS,LEDs (diy) and T5s and for a small closet grow see no difference in yield. adding a little UVA did improve taste and quality. I prefer T5s because I can easily adjust...

you need atleast 25 watts per sq ft to flower plants. that appears to be an aquarium light that would have a lot of blue and very little red. without knowing your budget it would be hard to advise you but stay away from cheap chinese LEDs on e-bay and amazon.if your budget is limited you may do...

had the same problem with my summer outdoor plants. I took a clear plastic pan put a hole on the center for the plant to come thru.cat could not get to the soil because of this thin plastic pan. problem solved
