Hey there...so personally I think Dinafem and mephisto are the most solid autos, not so many instabilities. Dinafem has a strain called dinamed and both the auto and photo variety has lower than 1% thc. Hope that helps ✌️ Theres also the sweet cbd auto by auto seeds and it's supposed to be 0 thc..i haven't grown the seeds i have yet though so i can't speek to reliability.
