I am a big OG Widow fan after going through Chemo. The taste is awesome. The yield is superb. 1/4 to 1/2 LB dry weight when done. Great for the nausea and easy to grow for the beginner in both soil or hydro.I got my patient some Death Star from a dispensary, collective, whatever you wanna call em, a couple weeks ago they claimed was awesome! I haven't had the pleasure of growing anything but GDP as of yet, so I don't know how good Deathstar yields, or where to find it otherwise. But DS did what it needed to well from what my patient told me. I'm going to look into that OG Widow and Astroqueen though. My patient suffers from nausea and a few other problems that it sounds like either strain would work well on. I'll also look into the Grapefruit Haze. With just the one patient, I'm always looking for good strains that yield and do the job right! Thanks for the tips all!
