How big is your grow area.
3by4 about 7 foot high,grow in water farms,3 plants at a time,600 watt air cooled hood
I'm not an expert but here's my 2 cents...... I just switched from a 600w hps air cooled hood in my 3x3 to a 1200w mars 2........I have been impressed with the flowering of my plant but in my Research Mars claims the 1200 will replace a 600 hps and i feel it has lived up to this claim.......I can tell you with the results I w as s getting from my 600w hps I WOULD NOT replace it with 2 300 watt panels and expect the same result..... THIS IS ONLY MY OPINION......
Thanks hot buns,nugnubs and strain,I do pretty good with my 600 just looking for something with less heat.gonna look into the Mars 1200
Here is all of the advice I can give regarding these lights. I assume you are talking about the MarsHydro 300w old model LED. Next question are you dealing with the "old" old model 300w which had 180w real power output or the "new" old model 300w unit which has 130w real power? Regardless 2 300w units will grow 3 plants very well.
I have 2 of the "old" old model 300w LEDs(180w draw) and frankly they are really over kill for my grow cabinet. I wish I had another 12" in height. One thing I will complain about with them is I wish they had a little more blue in their light spectrum for early veg stage. They will grow great plants with super tight internode spacing.

No dispute that 2 of them will grow nice plants but I'm telling ya..... even the new mars 2 400 watt panel is meant to replace a 250 watt hps and that's with the 5w diodes. Just by reading on there website I can't see how how 2 300 watt old panels could replace the output of a 600 hps ...... now I'm in a 3x3 tent and the 1200 watt is killing it... if your running the 3x4 you could easily run 4 plants under it or purchase 2 mars 2 700w panels so you have a little more options as far as how to hang dealing with plants at different heights......
HotBunz makes a valid point as far as the spectrum, but they still grow good plants. maybe a few 6500k cfl on the side would help with that
this would be my pick is I had the room. 2 you can angle and adjust as needed for even coverage. for me the biggest advantage is the lower heat output. a always, get the best you can afford.
Just want to make it clear in no way shape or form am I saying 2 MarsHydro 300w LEDs would replace the output of a 600w HPS.
