Hi I cought your thread about led and wanted to add my 2p. I have a few mars l hydro 300 and a few wyzm znet
the first marshydro I have is the old slightly longer first version they made and that runs slightly more in the red spectrum from what I can tell than the newer version that has 1 fan vent on the top instead of 3.the newer version 300 runs at 140+5 watts but the older mars runs at 135+5 watts but I think it has a better spectrum for veg??
the wyzm znet4 I also have is 350watt actual draw 135+5 watts. I pay £50 in a auction as new for the wyzm 300 and £30 for the smaller znet2 and I pay £90+ for the marshydro and I can honestly say I love leds for what they offer but have to say in my little experience so far that the cheaper of the two brands is about 30% better at bud development?? I have 1x marshydro 1x znet4 1x znet in a 60x60x140cm mylar tent and the leds are throwing somthing like 350watt so that's roughly 80 watts per sqf 4sqf being the area to cover. I
I have noticed a diffrence in size of colas on my plants for sure.nk whst I will do once these lights have has there day' is to gut them and keep the heatsinks for making some cxb cobs??????
Here is a picture of my little setup I hope you don't mind me posting a picture on tour thread? if so I will deleate?
My bb cheese us in love with the led lights trust me.
dint listen to the manufacturer spec about heat levels' they produce Alot of heat but not as much as hps but heat all the same. Always add good ventilation. My pall went led rout, payed out 800 on led in a 4x4 8 plants and they all died bar 1 from heat? He only used inlets without carbon filter lol
