How to Grow Weed - Grandaddy Purple?

Grandaddy Purple Feminized seeds can be grown indoors or outdoors - under optimal conditions, to avoid any problems during their development. Although they are compact and robust, moderately easy to grow and hardy, we should always prevent any pests.

You can use different growing methods to retain and enhance the terpenes and flavors of your Feminized Grandaddy Purple buds.

  • Use a quality substrate. Perlite, peat, or coco coir are ideal for moisture retention.
  • Thanks to the experience of our customers with our Feminized seeds Grandaddy Purple, we know that we can increase yields up to 20%.

For optimal indoor cultivation, Blimburn Seeds advises wide, vertical spaces and the use of the ScrOG method to obtain a uniform plane and increase the size of the lower flowers. If you plan to grow our Feminized seeds outdoors, we have developed a grow guide for optimal cultivation in any area of the world.

Remember that our cannabis plants also need good nutrients when our Feminized seeds are seedlings, in their vegetative period, and in their flowering period.

When growing cannabis seeds outdoors, choose the best date for your crop and a place where cannabis plants can receive the most hours of sunshine. If you would like to grow your seeds indoors, be sure to have good tents, textile pots for growing, LED lighting, an air extractor to circulate clean air, and of course a good carbon filter to avoid problems with neighbors or the law.

Keep daytime temperatures between 68℉-80℉ and nighttime temperatures between 7℉-9℉ cooler.

Grandaddy Purple Feminized plants need low humidity to thrive. Keep relative humidity (RH) levels at 55%-60% during the vegetative phase. Reduce RH to around 40% during the flowering phase. By harvest time, you can reduce RH to 30%.

Outdoors: growers in the northern hemisphere should sow their cannabis seeds in April for harvest in mid-October. Healthy Feminized Grandaddy Purple produce about 21 - 24 oz/plant | 600 - 700 gr/plant of buds each.

Indoors: these crops have a flowering time of 8 - 10 weeks and produce about 1.47 - 1.64 oz/ft2 | 450 - 500 gr/m2.

What does the Grandaddy Purple Smell Like?

The buds of the Grandaddy Purple are rock hard, soaked in resin and often have a crystalline sheen due to the amount of trichomes. They look as if they came from the moon and are excessively covered with resinous trichomes. The taste can be described as the perfect blend of berry and fruity flavors. Grandaddy Purple makes a delicious soft smoke and combines a wide range of effects including a strong and relaxing experience. Its rare genes produce a premium weed that is hard to beat.

Thanks to its large resin production, it is the ideal strain for the production of high-quality extracts and concentrates.

A good terpene profile enhances the flavors of the buds of cannabis plants. Terpenes are volatile organic compounds that are produced in the cannabis plant and have an effect on the aroma and flavor of the buds. The most common terpenes are Camphene, Linalool, and Valencene.

These terpenes act as a kind of energizer for the flavors of the buds, as they add a fresh, citrusy touch to the sweeter flavors found in the buds. Terpenes play an important role in the taste and aroma of cannabis which may have any effect on the overall user experience. For example, some terpenes have sedative properties, while others can act as stimulants.

For this reason, it is important to know the different terpenes found in a given cannabis strain before smoking it, in order to get the most out of the flavors and effects they produce.

Great Germination! All seeds popped and grew well. Buds are dense and full! Not as much trichomes as expected but not complaining. Short and bushy with a lot of leaf growth. Didn’t enjoy trim jail with this girl.
