420 Magazine

Hi Hydro91, I am so glad that you choose us, and based on your description: 5x5 area, 4 plants, I would suggest you use 4pcs of Mars II 400 + one Mars II 900 in the middle. This way will give you around 42~45w/sft, which will ensure you a good coverage and growing result; However, if you plan to use 4 Mars II 900, then you will get around 62w/sft, which will be a little too much for your space. :) You can order directly from our website: www.mars-hydro.com and use coupon code: MarsHydro to save some money, and if you have any question on lights, you can contact me or info@mars-hydro.com direclty. ;)

Thanks for the reply SmokeSara,

So you think 4x Mars II 900 will be too much even if I decide to run CO2 canisters?

Thank you very much for the discount code I'll definitely be buying the lights from your website and I'll look into your recommendations.

Yes, it will be around 62w/sft. Too much for the space. Usually if someone is using more than 50w/sft, the most is around 55w/sft, and they need very careful control on the air flow, etc. So it will be better to have lower wattage for that space.
