I see you have resorted to name calling like a child.
Yes I could blow your grow away with my 600 watt HPS. One thing those like you fail to understand is that some of us are interested in other things than just yield. I grow long flowering sativas. Some taking 20 weeks to flower. I also make seeds every run and grow smaller plants. I still grow more weed than I can use and give it away for free to my friends along with seeds and starts. In fact a friend of mine stopped by yesterday to pick up his starts. It feels nice to provide others with plants they need for their medicine. The smile on peoples faces is worth more than yield to me. There is something rewarding about helping others. At least for some of us.
So while you're on here stroking your own ego some of us are doing things that make a difference to others. Enjoy the stellar high yield grow you're going to have with those purple lights which are NOT better than an HID. But if you knew anything about lighting technology you would know that. And what did you call me? Oh yeah, a punk.
I'm a punk that doesn't grow for yield but as a hobby, strain preservation, breeding, providing starts to others, etc... I haven't bought weed in over 20 years. I grow enough to keep myself supplied with all I need.
Maybe one day you'll be cool enough to sit at the big kids table but not today. You belong in that booster seat at the toddlers table for now.
Another thing about not being as arrogant as you is that you end up with nice friends. The friend that stopped by to get their plants brought me a nice surprise. This is why I grow and share. My friend brought me some Columbia/Willamette river salmon as a thank you for the plants. It was a surprise. I thought he might bring a piece but he brought a cooler full. This is what it's about for me. Not bragging about some imaginary huge yield you're going to get from those subpar blurple lights.
