best led for tent?

i was looking at a mars300 or mars600 are these reliable ? for a 2by2 or 2by4 tent ? i allready have enough big bills and wanted to try led vs hps

Yes but not sure you'll get the same result as your hps; I run a mars300 panel as side lighting but it doesn't come close to doing what a 600w hps does. You need a lot more leds to equal an hid output wattage wise and that usually means dropping bank unless you can DIY one. I will say that the mars300 panel has worked flawlessly though for the past 2 yrs it just doesn't have the penetration that the hps has...

cool too have side lighting you must get huge bottoms , thanks for reply . nice to hear yours is running strong . i will proballly finish with hps since i cant afford multiple panels but i like the side lighting and will probally get a panel to veg with and side light
have a nice day

I use mars ii 400's, i find they are too intense for seedling & veg, but good for flowering, heres my cb dutch treat 27 days into flower under the mars ii 400: (i turn it off and use cfl's to take pics)

Because otherwise it looks like:


I would not recommend mars led's for seedling or veg... So far I only get miniaturized plants when I try

are you growing in a gh rainforest? I'm using 2 of their waterfarms & a Johnson 6- cob led I'm able to veg & flower with the same light

I use gh powergrower, i have also used soil: heres an example of my trying to veg under the mars ii 400 led: this is white widow, yesterday... She was started dec 5... Any attempts to seedling / veg under this light have resulted in midgets... With lights 18 inches to 5 feet away...

Try Viperspecta LED. Veg to flower is no prob and they do well with multiple 300's daisy-chained together.

If I'm doing a one to two plant grow can I make out with just one of those viparspectas?

These lights give me double the growth rate of my 400w HID with much better penetration at a further distance from the canopy.

Auto Cheese @ 5 weeks under 2 of those with no training.



Edit to add: You can save about 25-30 bucks a piece if you make em yourself.
