auto grand daddy purple

Auto Granddaddy Purple (Auto GDP) is an Indica dominant strain which was created by crossing two other strains, Granddaddy Purple and Hindu Kush. Hindu Kush forms the basis of many of the skunk type weeds of the modern era. Auto GDP is an autoflowering type which means that it flowers by itself without the need for the complicated lighting regimes that many strains require with indoor growing.

Auto Granddaddy Purps weed features a hash like smell and taste when you smoke it, with sweet undertones and a hint of exotic spices. The high is a strong body hit which can lead to some couch lock, especially for less experienced smokers. This weed’s medical uses include alleviation of muscular pain and treatment for depressed appetite.

Like those of most autoflowering strains, Auto Granddaddy Purps seeds produce plants that are on the small side although they can attain a height of up to 100 centimetres in the right conditions. The buds are dark green with a purple hue appearing as they mature, and they’re covered in sticky crystals. Leaves, which are not profuse, are dark green. THC content varies from 14 to 19 percent.

With indoor growing, these plants do well in soil or hydro and you can expect yields of up to 800 grams per square metre. Outdoors, plants can yield up to 900 grams each and you can grow this strain in cooler northern climes. Indoor flowering is from eight to 10 weeks while outdoor harvest comes at the end of October.

Any Auto Granddaddy Purps review will identify the fact that this plant’s autoflowering characteristics make it easy to grow and therefore a good choice for gardeners with limited or no experience. More experienced growers choose this strain for its dependable yields and potency.
