If you have to. Go to the store and get a few screw in 2700k leds to help suppliment light with flowering. You can buy a light socket with a cord. Buy a couple or a few. Whatever you can afford. Place them around your tent. If you get 4 14-16w ones (100w equivalent) that gets you an extra 40-60 watts.
This really isn't ideal but it will vastly improve your lighting for this grow and probably a few more until you can afford a better light.
I guess the people making fun of him doesn't remember typing into Google about "grow lights" and coming up with 1000's of pages of these lights, and "reviews" on how great they are. That's why I spend most of my time on ledgardner.com.
Check out that site bud. It has tons of info on diy led cheaply. Read all his blogs, and a lot of forums posts and it explains a lot of info.
This!!!
OP: standard advice for shopping grow lights: anything purple or pink: start by distrusting it intensively. A good manufacturer would list ppf/watt which is how efficient the light is at creating plant-useable light. In order to be reliable these tests should normally be done by an independent lab in whats called a sphere test. Dont trust spot measurements under the light: if you see a ppfd/watt make sure its a complete map, not only a spot reading.
A good manufacturer should also list components in detail (what power source, led chip with bin and hard its driven).
For just improving your current setup: any warmwhite led lamps (ikea or homedepo etc) with a decent lum/watt (+120lum/watt) should be fine to improve your current light situation. Remove the diffuser (the plastic sphere) for more light directed on the plants.
Read the forum and ask (with link to the light) and theres allways people ready to help. And a few more ready to troll and talk shit about the light. Cest la vie in the led section
