I'm just sayin with the light you described there is no way in hell you will yield anything. I'm not the only one with that opinion. Like I said that light you described is 15W, ask anybody on here how much you will grow with it. I may be using CFL's myself, but I've also got 240W's worth of them. It's the spectrum of the light. This kinda reminds me of the guy that wanted to put red jello in front of his lights to help with flowering. Sorry about the earlier reaction, I didn't mean to be an ass, but I did accomplish it. There's my two cents on why if you don't change a lot of things, and soon, you will not have any bud. Also your plants will triple in size when you flower. If you flower now, which the plant probably isn't ready for (From seed you need at least 4-8 weeks of veg, a clone you can go straight to flower unless you have an autoflower) and it's 5" now, then it will outgrow your space. If you posted some pictures, or told what you were growing in, or how far along you are or any bit of information we could help you more. I suspect that your 5" plant should in actuality be 1-2", but is stretched. Mine took almost 4 weeks to reach 5", but it is bushy as hell.L8R
