Lights question

[0123]

I decided to try to grow my marihuana with this kind of sistem - https://www.grow-weed-easy.com/marijuana-space-buckets (type link without minuses in grow-weed-easy)

My "space bucked" will be around 75-100 cm tall. How strong led lights do i need to use and how much of them ? How much does they cost and how much money will lighting my plant with them cost for a month ?

Thanks !

Though the site name in your post was removed automatically by the forum, I saw the "space bucket" awhile ago. Basically, if you decide to use LEDs, you need to decide on what kind of yield you want. You probably want to use 40-50 W per square foot, and a 12" diameter bucket would need about a 40W LED. You can check out costs from sponsors here or eBay, etc... Cost depends on your power rate.

So for 90 cm tall space bucket i will need 3 40W LEDs on top of bucket ?

Well your lighting only has to do with the square footage, not the height. So for a ~30cm diameter bucket, you would need one 40W LED. The issue with using an LED for a bucket grow is the LED needs to be a certain distance from the plant, so this may limit your plant height a lot. You'll have to research LEDs though to find those specs. I'd recommend using CFLs in this bucket grow though, as it'll be cheaper.

But if i put a mylar foil on inside of my space bucket isnt it the same where lights are ?

If i will grow on CFL lights one CFL of 40W would be same as one LED of 40W ?
