Hello fellow growers :D thx a lot Firstly, is the reason why my plants (especially cookies) are very slightly curling/folding at the ends of the leaves because the LED is too powerful?(Reason to be worried?) Secondly, should I start adding nutrients? Just 1/4 of Bio-grow for now?

Should I put the light on before sprouting or not?
I'm most likely going to be transferring my autos from paper towel into my medium, I've heard some people say have the light on before they sprout and some who say after it's sprout, which is the best thing to do?

How many plants in a 70x70x160cm tent with 100W?
Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx

additional blurple lights
I also got the blurple lights from my friend. To keep the temperature down I haven't installed them yet and not sure if I will. Will they make a difference if I add them next to the current LED? If so should I wait until the flowering stage or anything like that?

My Timer malfuntioned and gave them over 22 hrs of light?I was wondering why they kept growing this fast and big until i controlled the system and noticed they get to much light and stretching this hard. So i turned the hrs down to 16 to stress them into blooming, will 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?

Lightning question
Hey, Growers! This week I had to open together the two boxes, so now all the plants have both kind of lights. Do you think, it can have a negative effect on them, or maybe it's good at least for the 140cm height White Widow,because the bottom parts get some more light from there?
