I have a few plants under a 400 watt HPS light. The bulb is a cheapo sylvania lumalux and I`m not really impressed with it. I have a chance to get a philips Agro Sun. Has anyone had any experience with them. Would appreciate any info. Thanks
Get the Agro-Sun, it's a good bulb, make sure you change your bulbs every 6 months at the most if you have it in constant use, they will change spectrums as they get more usage on them......
