Actually, I think I phrase the words wrongly... haha.. I know K and watts are different.. What I meant was since the plants dont require that much light, should I lower the K or watts. Anyways, you answered my question.
Now, if K is the temperature, watts are the... erm, power generated then what is NM? The colour range of the light? So, since fluorescent light is white, I shouldnt be worrying about the different colours right?
Lastly, I still do not understand the fertiliser section and links that I've read... I intend to use root fertilisers(tablet) only... Can someone please just tell me what kind of tablet root fertiliser I should look out for? Please dont give me brand names.. I looking for a range of 'ingredients'... For example Iron should be 1-5, Calcium 5-8, something like that...
Thanks !
