Swim bought 2 bulbs. Soft white.300w compared. Actually uses 65. If I use both on a 12/12 for flowerin will that be ok. O yea its just 1 plant. Thank u

That depends on how big you want your plant to get. When dealing with CFL's more light is always better. I would get more. I just bought one of these CFL's (4,000 Lumens - 65watt/300 watt equivalent & freaking huge!) and I'm using it with four more 42 watt CFL's. Thats equivalent to 900 watts and over 11,000 lumens and my plants only 7 days old. This is my second grow with CFL's and thinking back, i wish I would have used more light last year. Good Luck!
