Looking really good man! I love how you're not afraid to experiment around and try different methods with your grow, you'll go far with cannabis growing by trying different things.

I've never tried the mainlining personally but I've been gaining interest lately, especially after seeing what you're doing here.

Sativas and Indicas definitely have some distinguishing characteristics, which you seem to know quite well, showing that you've been doing your homework! It's usually hard to know for sure when it comes to unknown seed strains, because there's so many mixes with Sativa and Indicas now that it's hard to find any "true" genetics of one or the other. Almost all of the known strains are muddied up by breeding, but I don't think that's a bad thing either because now people are starting to produce some really wild strains with all of the breeding that's occurred.

I 3D print those clips varying in size, from mini to monster size. I should start printing some new batches, and might even scale down to a super micro sized LST clip since there seems to be some interest in it :)

Keep up the great work @solominer! 💪
