Check that. I use what I had available, which does not mean it's the only choice.
In that forum you can see many growers using diferent brands and wattage.
I use Philip 6 x 10.5 watts@6500K bulbs for veg and Philips 6 x 13 watts@3000K bulbs for flower.
For veg most use either 5000K or 6500K color bulbs and for flower 2700K or 3000K Avd off course there are some that use a wide spectrum.
Take special note of Blynx thread, he's the one that started using LED bulbs like 3 years ago.
