Flowering wattage??

Definitely want to increase your overall wattage. I grow under at least a 600W Roleadro light, and flower with a Bloomspect 600W. I am upgrading to 1000W lights come springtime. I don't believe you will get the best grow possible with the one light. More is better. I do love the Roleadro light. low noise and hardly any noticeable heat. Really a good product, and durable. I had my light take a 3 foot fall and it never even flickered. Good Luck!

Agree with what Justa_retard says.. sorry to paste my reply from another question but i am inherently very lazy.. Wattage or power consumption is a bullshit figure that has no relevance to anything other the a lamps efficency. What you need to chexk is the light is giving full spectrum that you require and that has enough usable PPF to cover your grow area. The watts are only how much power is consumed to acheive this. Dont get suckered into the Watts game It matters not as long as the panel produces the required photons. The wattage just shows us the photon efficency. I am a live sound engineer and its the same in my trade. Some fool comes along and says "awww mate that sub is so loud how many watts is that?" well that does not matter what matters is the sound pressure being created by the given power consumption. This is called efficeny and wattage is a reflection of that.

All other considerations aside 30w/sqft is general rule and looks like that has been satisfied. Wattage alone you fine, light spectrum may be another issue but leave that to you.

Wattage isn't the only thing you should be looking at, when it comes to LED. Go to the "copywriting contest". One of the contenders "Nobody01" have written a post called "Lighting an area" - It'll give you some good info and math on what to look for in an LED. I highly recommend reading it.
