GDP Seeds Details

To set the record straight, we don’t mean all purple strains are indicas. What’s important is, Grand Daddy Purple seeds are an iconic crossbreed made from Big Bud and Purple Urkle.

This classic blend known as GDP is the pinnacle of an indica high, flower, and growth structure. When you’re looking for a good indica, you want it to put you down and keep you there.

These are the qualities that true indica lovers and medicinal patients go out of their way to attain. Grand Daddy Purple seeds should be in every grower’s genetic arsenal.

Throughout the growth cycle, Grand Daddy Purple seeds grow leaves that change color like a kaleidoscope. Robust and healthy sunleaves require weekly pruning throughout the vegetation period.

If the structure is well maintained during flowering, the buds will swell and produce large colas. Make sure to provide additional support such as stakes or plant yoyos. You’ll know it’s time when the buds go from slightly drooping, to bending at the stem.
