<span class="link_user">@bobo420</span>, I have read it on different forums. I would measure it if I could. :)

<span class="link_user">@bobo420</span>, it has lot of potassium and some phosphor too. Worth a try.

<span class="link_user">@Jaindoh</span>, Hi! Thank you for your comments! This is grown under a 30W LED, but I just added a picture from the ones which grown pure on windowsill, and this is not so promising.
