Between 12 and 24 inches.flight175 said:what is the optimal distance away from the plant I should have my 400w hps? that is for most growth of plants. can you put the light as close to the plants as you want aslong as there is no touching?
not really sure if it remote or built-in. could you explain to me what those are?Biffdoggie said:If the light is vented it will make a big difference also. Is it a remote system or the built-in type?
