get a few nice hybrids. I am growing out Cheese from Greenhouse Seeds, White Domina by Kannabia Seeds and Jilly Bean by our own TGA Sub Cool.
get a variety after all its the spice of life.

Well your options are limitless depending on your budget. Here is a quick example from the top of my head:

Try the church by GHSC and medi bud marijuanaseeds.nl

Video of them.......https://www.rollitup.org/hydroponics-aeroponics/396456-video-ghscs-church-dutch-medi.html

Both yield around 650-750g per sqm.

Also try this website, they have a really comprehensive list of all the strains including loads of details on the strain. Put it in a search based on a criteria and bam!!! choices!

its my honest opinion that you are crazy for not growing really good strains.

while I could imagine that the first few rounds of growing if you are new to growing, it might be ok to grow whatever grows. But if you are really trying to do something and taking the time and expense of growing something that could put you in jail for 5years, your crazy for not spending a bit of money to get a strain. Genetics are more important than conditions in my opinion.
