More false noob info. You dont NEED any special spectrum for anything and the truth is that mixing spectrums will help with plant vigour and help the plants to saty healthy and green. Its bad info like this that is fucking this site up.You'll need 6400K or 6500K for Seedlings/Vegetating and 2700K for Flowering and no, you can't mix the Bulbs. Btw remember that you need to cover only the Plants sq.f with your not the Tent
You need 3000Lumens by sq.f of the Plants, now if your Tent is full you'll need 4x4=16x3000=48000Lumens
Good Luck
Ok lets start with your first statement about needing 6400k for vegging. Well I (and thousands of others) use an HPS start to finish and when I use my T5 I use bllom bulbs through the whole grow. As far as your second statement where you said you cant mix the bulbs, why would lighting companies be selling dual arc HID bulbs for then? There are plenty of threads on here about the benefits of a dual spectrum grow. So again I ask you to stop spreading Bad info after coming here and reading a copule threads from people with no more experience than yourself and deciding that you know enough to start giving people advice that really want to learn the facts about growing unlike yourself. I am no expert no but if you look around I have pics of no less than 40 plants I have grown successfully using many different styles and lights with good success so yes I think I am qulified to question your short sighted opinion to support my own.
Imagine that!!! A man with experience has also challenged your opinion with facts. I am not trying to be an asshole. I just think you should learn a bit more before we end up with a new member spreading your bad info.
You are certainly entitled to that.
wrong!
Wrong again! 2700k is the color temp of bulb...light cycle induces flowering...ie.12/12
