I have to mostly agree with @Hellraiser
I’m a fan of HLG lights. I have many of their lights.
I have put together 3 260w kits with ease. The directions are simple. If you’re slightly mechanically inclined, it will be a piece of cake. If not, I’m sure there’s a step by step video out there on YouTube. Or I’d be happy to walk you through the process.
Two other options would be to buy a 300 RSpec or a refurbished 300 RSpec. The discount code Hellraiser mentioned works for both.
If you only have one tent for now, you can keep your Blurple light in there along with whatever light you choose. It’ll just add to your harvest. Just make sure it doesn’t get too warm in there.
Also, many of us have been bamboozled into buying crap lights. Here’s good read.
