The regular Lowrider reports I've read give it 6 or 7 stars out of 10. Try one of the Lowrider crosses. They are more potent than the regular Lowrider. I grew some of the Master Low (Master Kush x Lowrider). It had a nice kick to it and a spicey smell. I bought mine from Gypsy at Seed Boutique.
I know it has been crossed with other strains as well. There is a blueberry/lowrider cross and one crossed with Matanuska Thunderfuck. Search around the web. You'll get a better idea on which one you'd like.
Here is a link to a forum that has info.
