I don’t get how people say the strain is 100% Indica. It can’t be if it’s just a phenotype of OG Kush then it’s genetically the same as OG Kush. It doesn’t matter if it’s got more Indica like effects it might lean more towards the Indica side, but you can’t just say it’s 100% Indica or 75% Indica because technically it’s the same genetics as OG Kush and if I’m not mistaken OG Kush is like 55% Indica therefore private reserve OG or OG 18 is 55% Indica and there’s no way to prove any different. You can’t test the genetics and say oh this is so much percent Indica no it was made with two strains the same two strains as OG Kush was so therefore It’s 55% Indica 45% sativa

A great strain for pains and sleep. It doesn’t have any hunger effects to it either.

I have spent a good amount of time thinking about this strain before deciding to review it. Initially, I did not like Private Reserve OG. I thought it tasted like someone grabbed a random fistful of greenery, spritzed it with perfume, then shoved it in my mouth. I hated the taste and I really didn't feel much of anything the first two times I tried, though they were low doses. I gave it another go about a month later and I can't believe I almost gave it up. This strain is an amazing stress reliever while not clouding your brain. I feel content, relaxed, and relatively stress free at the moment. Even in high doses, I can still work through the light haze of euphoria and get my work done. It's a great strain for listening to music too. I'm still not a big fan of the taste, but I'm so glad I gave it another chance because it was worth it. My husband now uses it daily at work for stress and pain and it's his top #1 favorite.

I love this strain! It’s my all time favorite when grown like Farm Fresh from Herbal Wellness North in Phoenix Az. I love the smell, the look and the sticky texture not to mention how it makes the body and mind feel relaxed and pain is better. Love ❤️ it. I’m 71 smoked 50 years medical the past 12 years. I feel I’m a good judge ✌🏻

I was given this strain by one of our growers. I smoked before bed and got a bad headache and couldn’t sleep at all throughout the night bc my anxiety went through the roof. I was pretty scared as my heart was pounding out of my chest. Ended up having to take my emergency anxiety meds. I read the great reviews but the sativa in this hybrid was too strong for me.

So I had this in vape pen form (Jeeter Juice), and I'm not usually used to this level of high (casual smoker, delta 9 gummies user) so getting this much is an absolutely more potent experience that's difficult to squeeze down into perspective but here I go; you begin feeling this intense mid body lifting effect that makes you wonder if you've been on a ride of some sort this whole time, and throw some euphoric mind potential creative thoughts while in the background there's this feeling that you can do anything, and for me I kept finding myself trying to do different tasks bht with such accuracy it looked like I was in hyper time from my own perspective. Music sounds and feels quite lovely. Extremely uplifting and sharp focus mixed with euphoria and bliss and forgetting that technology even exists.

This stuff changed my life. I discovered how well high doses of heavy indicas work for my anxiety and PTSD symptoms due to this strain. Unreal. It tastes really great, for one; I was getting a sweeter profile than I expected based on what I read about it. Almost some vanilla custard type flavors. Just amazing. Then, I felt all the anxiety lift and I became very motivated and very positive, but still incredibly relaxed. Lastly, I was able to sleep normally, and with no nightmares when pairing it with my nightly dose of trazodone. Truly changed my perspective on cannabis and I’ve been hunting for it ever since!!
