will two CFLs be enough for one ore two plants in a small tent 60x60x120

get a 400 and you wont be sad, i had a beaming smile for weeks after changing from 600 watts of enviro, fucking amazing, from 5-6 oz plants to 15 oz plants

weird thing is this 600w one i found is cheaper and i pretty sure better than 400w ones its second hand reconditioned thats why its so cheap but will it be too much power or heat?

600 in a 60 x 60 cm might be over kill really but could prob be done with a reasonable inline fan
