After alot of reading up on this site it seems that I would get a far better result using a 400w hps.
My problem with this is that there's no insulated panel's etc on the roof under the slates just a layer of water proofing and then the wooden joists so im very worried that without insulating my whole attic an hps would be a bad idea. Can anyone help explain what my best option would be?
Thanks in advance
