Nothing is labeled

I like the looks of these:

Ya know, I could swear I've seen those @ Home Depot but I just went to their website and no-go....

I just found a YouTube channel called 7 Pot Club and I noticed them.

I  make my tags from those used  vinyl  mini blinds...I cut them to what ever size ,use a # 2 pencil & they last for years.
Never fail in my case...My grow season is short compared to say people in California or Florida etc where the tags 
get a stronger case of the sun rays, year round  here it's a kinder gentler sun    so the impact on the tags
is not as harsh.YMMV.
 

You can still read the #2 pencil on my mini blinds I used last year. I even erased some and re-used them. There is a method to the madness I promise

label makers are the best! mine are still sharp and clear from 2 seasons ago!

Best thing to use is a #2 pencil. I have orchids that are over 20 years old with the same label.
