It all depends on the size of the plants! Maybe after the 3rd week of veg is when they really start needing more light!

Best LEDs or small HID to replace 1000W dimmable HID for small space
I'm using a 1000w HID setup I had from before, running at 50% in a cool tube. It's loud and not efficient. Maybe it's time I switch to LEDs or a 250 HID. I don't want to sacrifice bud quality but I'm low on funds. Any recommendations for a good light that will fill this space?

raise lights during stretch?
Should I raise the lights during flower stretch to maintain the same distance from light source to canopy? I notice that my plants continue to get taller than most. I know the stretch is natural, but I'm wondering if constantly raising the lights with growth is the right approach

Light intensity? Should I dim?
I'm having a light-science question. I have 5 bulbs, 11w each, total 55w. I know this is not much but anyway. Should I dim the lights for seedlings even If I have this low setup? I mean, does light intensity affects seedlings' health? Or 55w can work on a maximum level?
