Do I need more or new lighting ?

You can never go wrong with hps lights

@Y0ink mentioned some good brands. You want either a quantum board or the newer bar style. Most manufacturer will provide a par chart. This site has some good info and testing results with some of the more common lights. https://www.cocoforcannabis.com/grow-light-guide/

From my experience, which isn’t ANYTHING close to some of these guys on gd, but I’ve learned to do my homework and save up for a good light for my specific area, rather than buy say 3 “ok” lights that will work. How many plants are you wanting to grow? I use a rule of thumb and give each plant 100watts to the wall(I’m guessing it’s 2000w led=200 watts to wall, give or take. So 4 plants will go start to finish under those…I think 😂. I’m just a newbie. Happy grows ahead brother!

Yes I don’t mind paying for better lights that’s for sure

Better lighting. Don't go by pretend watts, go by actual, and use a lux meter.

Whit that budget you could have bought a good product from Marshydro,for example 🤷‍♂️ I wouldnt put those lamps in my tent tbh... If you can,refund or sell and check in the light section of growdiaries,im pretty sure you are going to find a good product! marshydro,lumatek,vipar,spiderfarmer are good,but is up to you,also on your budget! Good luck 👊🏽🍀

Yeah you could veg okay with that I suppose but really insufficient for flowering. And yes it’s actually not 2000W. Blurples aren’t as good as a lot of stuff out there now. I’d recommend some bar type lights for that space

2000w is advertise watts. The lights actual wattage will be around 2-300. The short answer is no, you prob have enough for a 4*4 without CO2. You need to look at par values. A good par for flowering will be between 600-1000 without CO2 and 1000+ with CO2.
