Hi, you have a few options.. you could either run 3-4X 250W ENVIROLITEs or 6X 125W ENVIROLITEs, or a crazy amount of household CFLs, Personally I would recommend either of the 1st options, but option 1 will still set you back around 180-250 Quid (uk pounds) inc CFL hangers or option 2 around 210 (uk pounds) inc. CFL hangers, my question is would you not prefer to spend that money on a decent air cooling system so you can still run your 600? what type of grow are you doing is it in a cupboard or in a room etc? write back soon and I'll give you a more detailed answerhope this helps - STELTHY
As far as I am aware the 300w CFLs are fake ie the actuals watts are more like 150 actual watts... If I post you a pic of how I have my 600 in a cupboard setup maybe this could help you I'll add a link too cos its an on going work in progress at the moment- STELTHY
will x 2 300w Blue CFL be ok? it should output around 40000lumens... 10000 per sq ft... therefore, isnt this enough?
Here is a link to my latest thread... tackling heat issue's is one of the topics tackled... but its an on going complet-ish from start to finish feel free to take a look and/leave any comments etc https://www.rollitup.org/general-marijuana-growing/320402-stelthys-600w-hps-project-new.html as long as its relavent its all good- STELTHY
