Need help deciding on a light for a 2x4

Hey guys! Wanted to see if I can get any help choosing a light for my 2x4.

I am new to growing and I haven’t pulled the trigger on anything because I want to feel 100% confident and content with the things I end up getting.
Im hoping to set up 4-6 buckets depending on bucket size in my 2x4 (drip system)

I want a 600w light, with as much coverage and penetration as possible.

not sure which light to go with, I may just get a 2x2 for seedlings and clones and leave the 2x4 for veg and flower, I’d need a light recommendation for that as well. But mainly maximizing my 2x4.

thanks guys!

Are you wanting LED or HPS lighting?

I’ve used an SP6500 (650w) by mars hydro that performed very well in a 32”x60” tent. Would probably be a bit much in a 2x4 unless those walls are kept at bay.
I think if you got this same size tent you’d be happier & fit more plants. I’m currently running 8x 3 gal pots under it. These are old pics. And the only harvest I’ve had with this light, and in this space.
If you already have a 2x4 I’d suggest something smaller.. maybe 320-350w max with a dimmer.
multiple lights isn’t a bad idea if growing different strains at once, as they can adjust. Hope you find what’s perfect for you. This is all the experience I have with that many watts in a similar space.

This light from Viparspectra is 450w
The par maps available at in a 2x4 setting.

I have a discount code available for lights & other things on this site if anything there peaked interest.

No regets lights. Long life....great warranties and no regrets.

I'm running an HLG 250W Veg Pro and have to keep it at 1 so as not to scorch my clones LOL @Laughing Grass runs two of the 350R's, I considered them but worried they'd be too strong for my intended purpose.

Having run both cheap lights and HLG, I think anything other than HLG is a compromise.

I'll soon be replacing my old HLG 300 with a Veg Pro. The old girl just keeps going.

I would buy two of the smaller LED panels, their price/performance ratio are higher then bigger panels.

Phlizon has great deals on their 100w led panels currently. It's nice to have two panels to be able to have to different levels of canopy.

I appreciate the insight! I was looking at the HLG Diablo 350r, mars Hydro sp300 and the sp6500. Really want the sp6500 but I agree with you, it may be a little too tight.

I do really wanna stick to the 2x4 because it makes the most sense for the room I’m putting everything in.

I was looking at the grow craft x3 and x6 as well but I feel more confident in HLG.

I guess the question is, how tight would the sp6500 be in a 2x4 ? Would most say it’s a bad idea, or maybe I can get away with it?

I changed my flower room to their Diablo X. The plants love that spectrum. I was stunned how well these lights perform.

The sp6500 is too much for that space. If you can afford it, get the 350.

of all the lights you mention.
HLG has no complaints.
Buy once and love it forever...its like the Toyota of lights.

Id buy the HLG 350 Diablo.

I’m liking the sp3000 in 2x4 spaces.

Hello,suggest you can consider Mars Hydro SP3000 Very suitable for 2x 4 spaces

What about two of these (but only the design with the new lens)?
ViparSpectra 2023 Lens Design XS1500 Pro LED Grow Light. 150W.
$139.99 less a $50 coupon on amazon.

The viparspectra XS4000 kills it in a 2x4

I was using LED i have a 240watt panel and a 100 watt panel but i didnt like that the spectrum didnt have uv or ir/nir so i switched to CMH im a much happier camper know
