I just checked your profile since your have a big brazen mouth. Goodness and then you’re talking about not taking advice from YouTubers and IG? They should take your advice right? The one where you don’t know anything. I saw your lousy postings, I thought for a huge mouth like yours, you have golden information there. You don’t even fucking know how much is too much light! So to answer to that poor person who never got answers he was seeking, it’s very simple. Light must cover entire grow tent, there can be extra free space on the edges but the more you cover with light the better. 2. It makes a huge difference which light to buy and to which give a following answer, there are lousy lights that don’t do anything, you can literally have your plant touching the LED and it still won’t burn. Such weak LED’s you can put a hundred of them in a tent and you still won’t burn your plants , they don’t work well because they don’t have enough power, that includes all the major top rated lights such as Electric Sky, SpiderFarmer, MarsHydro, GR8 LED, Kind LED and I believe these are all the garbage that I had to go thru in order to find the perfect light. When you have a powerful light you must keep your plants min 20 inches apart or else you’ll get burn. If you don’t get your plants burned in 10 inch distance then you can toss your garbage light as I have. Once you get a powerful light, you only need what manufacturers suggests which usually they state coverage area, such as 2x2. So in my tent I have 2 lights that cover 2x2 area. So I got it fully covered in 2x4 tent. Now this is an expert answer, not oh I don’t know ... da fuck do you know ? It’s ok not to know anything as long as you’re not a dick, but you’re acting here not only like the shit, and not even like you own this forum, but even more like you know all answers, rest are idiots and one need to beg you for help. God forbid to ever be dependent on someone especially people like you. So once again, I don’t give a shit how loud you scream there, when you got zero actions to prove. You got one lousy photo of some plant on your profile and that’s it a freaking world’s best genius expert all of a sudden smh.
