What led light should I get

All mars hydro range are good personally in that size tent that may be overkill the ts2000 would be perfect in my opinion

What about the mars hydro fc 3000? I have a 2x4x4

For that form I would go with this: MARS HYDRO TSL 2000W https://www.amazon.com/MARS-HYDRO-Spectrum-Hydroponic-Fixtures/dp/B07PLZLKVM?ref_=ast_sto_dp looks perfect for a 2x4

I have a 2x4x4. What you guys think of the Mars Hydro Fc 3000?

Iam going to agree with Baker420... Iam growing with 3 Marshydro Led ( Quantumboards) It just depends in the size of your Growspace , wich fits in the best For more information just get me per PM or get in contact with the MarsHydrd Representant here on GD..... The Quantumboards have ahigh quality Light, and the Marshydros are avialable for anice Price Iam very satisfied with those lights I have the TS-1000, 2000 and the SP-3000........ The last one I bought together with the fitting tent... they have bundles on aliexpress, I lwet you the link in the Comments

The new Samsung lmb diodes are possibly the best LED diodes on the market so what ever brand or model you choose I suggest searching for one that uses these, hope this helps I'm sure a more experienced LED grower will stop by on your question and have some better insight , happy growing

I like the mars hydro range I have the ts600 but if I had a bigger space is have the tsw2000
