Another question as I was reading your post you recommend full spec bulbs over over hps do you mean the dual arc bulbs or ... I greatly appreciate you teaching and answering my questions

No I meant cmh, induction, or led. Hps is dead tech that has barely been improved on in the last 40 years. All others are killing hps. Ironically led has been around since the 1920's and induction since the 1890's .

Id say dense nugs can be grown in any soil/medium, but not with any light. U could have the best genetics, nutes and environment but if u dont have enough light u cant grow dense shit. We use HPS and LED's for a reason, the rest just simply dont work as well to flower cannabis.

I don't agree. I have 4 induction / led combos 460 watts each covering a 5x4 per light. My buddy has 4 1000's covering less space than me. I produce far denser buds than him. My straight led grows produce denser buds than his. All mine are more colorful and far frostier. Led works awesome. Hps doesn't even compare.
here is a comparison thread to check out too

led's produce quality but not quantity. There is no way i could pull what i do with a 400w hps from a LED in my tiny 2x2x5 tent.

Wrong again. Quality led at half the watts of hps will match the yield of any hps light . Its been proven on here time and time again. 100's of times. That link ^^^^^ I posted is proof of that. I ran hps for over 10 years and I would never go back. There only a small amount of companies that make quality led panels. Area51 led, Apache Tech, Hans led, Onyx, and the diy cree cxa cob leds. Any other brand is crap and use low bin leds. Cree cxa cob leds are killing everything with the least amount of watts.
My last yield of a 155 watt Area 5 led in a 2.5 x3 was 6 zips and I got 8 grams of ice hash of that trim. 9lb hammer and jilly bean were the strains 2 plants in 5 gals. I have 2 10 gals under it now in a 3x3. I will probably at the very least pull 8 zips

damn i had No idea it was invented That long ago! But I still just don't have the money for the oother, for now I Have to stick with hps which will be a Huge upgrade from cfls. And once I start saving money Then I will start looking into upgrading again.

cmh is still pretty cheap.

the cmh has a quartz crystal coating around the bulb. So its opeb reflector rated. Plus glass would block out the uv anyway. It runs off a 400 watt mh or switchable mag ballast
they make an 860 watt that runs off a 1000w mh or switchable mag ballast

bit that wouldnt cover 4*4 completely would it? and isnt it just a mh?

it will do a 4x4 better at 3x3. No its not an mh. Mh use an aluminum arc like hps. Cmh produces more lumens per watt on an mh ballst than a switchable
here is the spectrum for the philips all start 330
its not about watts but par and cri. The has a higher par rating than a 600w ushio and hortilux hps. Hps cri is 25-35. Cri of this bulb is 93. Closest to the sun. Its output appears very white like induction. or being outside. Cri - color rendering index. The higher the cri the more even the spectral output. Hps has a high yellow/ green spike. Very uneven ie low cri

I used to use a 2:1 split of hps and mh to get a good spectrum. CDM is much better.

Don't know exactly. Like 2 months. That's only a portion of the plant, the plant is on a 6 foot by 4 foot trellis.

my density has gone up since I started leds. today im doing straight cobs + ROLS = dense dank nugs! btw who ever says leds produce quality over quantity is right about the quality but wrong on the quantity, dead wrong, the yield factor has gone up, proof, LED SECTION
