My grow kit will arrive this week. is there anything I need to watch out for considering the fact that they only have stood by the window (mostly cloudy weather) for most of their lives? I don't want them to get overloaded with the rays of my growlight 😇

LED lights for veg-Viparspectra xs1000
I have the viparspectra xs1000 light. I turned up to 50% intensity and plant is about 30cm from canopy. Is that right for early vegetation stage?It looks healthy to me but could be wrong. Was going to turn up to 75% later, then 100% for flower. Do I need to move closer the light?

24 or 18 and 6
Been running my lights 24 hours a day on my seedlings. Since I am growing autos, should I be at 18 and 6 now? Or should I keep running them 24 for the first couple of weeks to help veg up little before giving rest? This is my 1st time growing autos and 1st indoor grow in 20 yrs

How many watts do I need for my small tent?
I am using a full spectrum LED that draws only 30W from the wall but it might be too weak since my plant is getting lanky. I have moved it closer to the plant but now I am afraid of over-heating. How many watts LED would be sufficient for my 40cmX40cmx120cm tent?

Is anyone else using Spider Farmer Lights ? How was the stretch on your plants using these lights ? My plants stretched from 10 inches to 30 inches in two weeks & another week of stretching left.😒 Not a big deal but I have a 60 inch tent , not a lot of room to LST.
