Light distance for Seedlings
My question is my 2 seeds have popped out and I am using 3- 8.5 watt 5000K LED lights to light them up. Both plants are under humidity domes so how far should I put the lights above them? I have them in a make shift grow tent for now as my regular tent is finishing up a grow.

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

what are you suggestions on Home-Made LEd grow lights and also if you can reccomend cheap alternatives please how i can make this work?
Hello there, fellow growers. I am facing trouble finding a LED grow light in my country right now. I saw a couple of DIY ideas to make a homemade LED grow light using a panel and LED Strips. Can I grow using my own grow light? how many watts of led do I need for 3x3 space?

*FC-E4800 Hanging Distance*
1st grow -4x4 with 480w Fc-e4800 in early veg (auto) but I am very confused on light distance and dimmer %. Apart from recommended distances, can someone point me to how I can establish the correct height and dimming % required based in the grow cycle? Currently at 30% & 55cm

Adequate Lighting with this LED?
wondering, do i need more light than this spider LED 1000? If not, should i be cranking this spider LED to 100% or keep it at 25% (thinking this is hitting that 20-30 Watt/ft2) (total sqft is at 11)

Added a light, how far should I hang them both from the girls?
I have added a Mars Hydro TS600 to my tent along with the Spider Farmer SF1000 in my 2x2, how far should I move them up away from the plants? I'm guessing I don't want them as low as the SF1000 was on its own which was around 15" Thank you lovely people!
