ive run leds for the full run veg and flower and if you pick the right leds (read expensive) theyre great the whole way through but the cheaper leds are fine for veg not great for flower i ran a 720 3w diode 11 spectrum led setup with good results

How many plants will a 720 do? How many lights is that? Also i was thinking of doing two 90 watt for veg and 2 hybrid 5 spec lights. Idk your the pro. This going to be my first inn door ive only done outtie very i must say so i want my inside to come out good.

i did 8 plants in a 4x4 with 3 leds totaling 720 watts leds tend to cover a pretty small area

Yea i hear that! Thank you for the help.

they do produce heat just nothing like HPS/MH.

Im aware! Im going to have to temp control my room

they produce the right amount of heat for my room.

I am just completing my first grow. I used 16 of the SuperGrow LEDs for a 4x8 space. I should be harvesting in a week or two. My first impression is awesome yield, especially for dirt. I love the LEDs and would never switch. Low power and very low heat. The room is upstairs and its gets hot just naturally in the summer but a single 8k Btu AC seems to be keeping it at 70 degrees no problem. Each light only draws 0.25 amps. In theory you could run 60 lights on a single 15 amp breaker. Go to their website and read all the stuff. I am a believer. https://www.supergrowled.com/

When we say that cheaper ones are not good for flowering, what is the reasoning? What about for a little one plant (lol) setup?

Awesome info! Any pics of you garden?

See my post "Nice bud from LEDs"

Its not the expense or the brand of the LED which will make it more or less effective. You need two things for an effective light - enough watts to penetrate the canopy and allow for photosynthesis and the right spectrum of light. For flowering, Deep red 660nm is essential and then most manufacturers throw in some 630nm to round off the red spectrum, from there it varies. Some use orange, some yellow and then blue (some where in the 450 - 460nm range) white, some include uv and infra red diodes for increased resin production. (The bands used varies between manufacturers).

Its this blend of light produced by the LED and the power of the diodes used (preferably between 3 and 5watts for better penetration) that produce a good grow light. Although you can use less energy when using the targeted light spectrum of LED, the adage 'Watts is Watts', still holds true. Or maybe 'Sufficient targeted watts are effective, productive Watts' is more appropriate. I'm not sure what it is or if its yet been calculated but there should be an ideal wattage per square foot for LED's and by that I don't mean the claims made by the manufacturers. As a starting point I don't think there would be much point using less than 300watts of LED lighting, any less and CFLs are probably on par and a lot less expensive. Using multiple panels also allows you to place plants in the overlap between the lights as well as give them point multiple points to grow towards which, will encourage bushier growth.

Plants literally absorb the available electromagnetic energy (from the specific spectrums they use) of the light for their processes, less available (useable) energy = less plant.

Its never as simple an equation as which light is better. Air exchange (Nitrogen 78%, argon, co2, oxygen levels), water quality, nutrients, substrate and atmospheric heat and humidity will affect the plants ability to undertake its processes, grow and bloom.

But less talk more LED bud porn.








Despite certain comments to the contrary, these lights can work effectively and will produce some serious product. But just like HID there are certain pros and cons and all the aspects of your growing have to be on point to maximise yield.
