Hi Experts, first time grower here in need of some info on lighting. I’m growing in a 60x60x120 cm grow tent with a 300w full spectrum CFL. Is it best to have a reflector for the light? The guy in the store said I didn’t need one? Or is it ok as it is? Should I buy more lights? See picture of my set up. Any help/advise please 420 gang? The way it is means I can’t point the light or get it close to two separate plants at the same time
