How many Watts needed ? Led or CFL ?

Or hid I know nothing about bulbs other then they suck... Nasa picks Led for indoor growing for a reason... listen to Nasa :).

But if you wanna yield close to Hps your gonna have to invest some money period.. Or get a 1000 watt hps bulb and get weights that way.

It's up to you Floyd... But four plants I was just running like 400 watts per plant I am trying 600 next.. like I could run 1 plant with 600w of leds, I am doing this right now but pay not attention to lux.. Lux is not a good way to measure anything other then how bright something is. if you can.. Find an Led is the 390-800nm range.. If you can find something with UVB your even better.. Depends on how much money you wanna spend or much much work you wanna put into it.. There is not "perfect number for watts for plants.. I plan on growing another plant with 125 watts of led. There is a lot of complex things going on and I don't wanna oversimplify something that is absolutely the X factor to growing Cannabis.

Hey, buddy! 👋😇 For vegetation, a CFL with a total power of 500 W (maximum) will do. For flowering, you’ll need an LED or multi-spectrum LED or a light source with a predominance of red spectrum, also with a total power of 500 W. 👌 It'll be useful to know your lighting! You can measure the light intensity (lux) in the cultivation area above the plant! Download a free app called "luxmeter" from the app store on your smartphone, clean your phone screen well to remove grease and dirt. The light sensor is located on the screen side and often competes with individual lux meters. Check the light intensity above the plant. Adjust the lamp height so it doesn’t heat the plant to shock states but stays within the lux range. Install the app, and you’ll remember me more than once, bro! It’ll be like a compass for your lighting! Effective light intensity ranges, starting from planting the plant: Day 1 (250-500 lux) Day 2 (500-1000 lux) Day 3 (1000-2000 lux) After five pairs of leaves, full vegetation (2000-20000 lux) Flowering (20000-90000 lux). In theory, the most optimal for flowering is considered to be (45000-65000 lux). Try not to exceed 90000 lux. Otherwise – 100% problems due to overly active processes in the plant! 👆 Good luck, bro! ✊😇
