Thanks,but now it's just vegging phase, would i also need red spectrum ?or blue?shall i mix with 6500K or 10000K??i really dont know a shit........yes you can mix them ,you want more red for flowering (2700k ) and more blue for vegging the plant (6400k) so if your gonna mix them up id go for more red , youve allready got two 6500k s so id get more 2700k , coz your gonna need the red for flowering .
yes,i plan to buy a HPS for my flowering phase.so i just focus on my vegging~~~~As you say, i should buy couple of 10000K or 20000k tubes to mix,right??If you just want another couple of flourescants for the vegging phase then get some more 6500k's. But two 39w should be enough for vegging a few plants anyway so you might aswell get some reds (2700k) and use them in the flowering to save you having to buy them later, because you NEED reds for flowering.
i will buy some 6500k's today,i appreciated your kindness,you have solved my serious problem.........6500k's are perfect for vegging so there's no point mixing, you might as well just get some more of the same because 6500k's kick out all of the spectrums you need for vegging, if you used any other kind of light you'd just be wasting energy on light spectrums that your plants don't need. good luck.
