I've gotten Hindu Kush x Skunk #1, Mendocino Lavender, da purps, williams wonder, and chemdawg D from Harborside for previous grows. Here's my rundown.
HK x Skunk #1....Monster yielder. Hashy taste. Medium THC. Decent overall. One small problem, it came with spider mites! I know this because I go over all new clones with a magnification device before putting them in my grow room. Given how early it was, I hit it with one treatment of Avid and haven't seen a mite since (fingers crossed here).
Mendo Lav......awesome indica. Great taste, potency, and bag appeal. Not a super yielder. Connoisseur bud for sure.
Da Purps......most beautiful plant I've ever grown. Turns purple without introduction of purple maxx or dropping the temps. It seems predominantly sativa, but isn't a jumbo yield like the HK x Skunk 1. Again, connoisseur bud. But a higher yielding one than the lavender.
Williams Wonder.....huge buds, great smoke, glad to see this strain still around. Ended up with powdery mildew. Could have been systemic and there at clone time, could have been me not putting enough airflow across my first scrog..
Chem D....couldn't have been the real thing. Looks nothing like most pics I've seen. Smokes nothing like the Chem D I bought from harborside. Ok yield. Got powdery mildew along with the Willies Wonder. I'm never buying OG fill_in_the_blank or Chem fill_in_the_blank anything anymore....they have became buzz words for people to jack up prices and nobody really knows what they are other than this hippy sold that hippy some nugs at a dead show and the worlds highest quality bagseed was born. Then they were "re-united" at a Phish show and somehow Mass Super Skunk, Sour Diesel, snowdog, and OG Kush (Seemingly 80% sativa and far from any kind of real kush) got tossed in there. Yet somehow from those original (I think) 11 seeds there is now what seems to be about 50 crosses, etc....
Sorry to rant. I have had bud as mentioned before called Chem D and OG Kush and found both to be excellent. I just wish someone could peg some real genetics on them. It it a sativa, an indica, a cross (seemingly mostly Sativa)? Where's it from originally? I've seen it advertised in dispensaries as both indica and sativa! I know Harborside has a gas chromatography device to determine thc percentages and vet out mildew and mold.....but I wonder if a machine exists that can tell exact plant genetics? If said device existed I wonder how many purple strains would end up being either da purps, purple eurkle, or GDP? and how many sour D, platinum, og, tahoe og, etc....kush's would be the same.
All in all I don't think you can beat Harborside. Just go over each clone with a magnification device before introducing to your grow room. This advise is not limited to Harborside however. This could happen anywhere. IMHO Blue Sky sucks for clones. They have some good strains, but sell in these "six pack" blocks. which means you end up cutting up healthy roots to separate them. No idea why they do it that way, but it's lame and a hassle in my opinion.
Hope this helps.
my 2 cents. Happy growing everyone.
