My Experience Growing GG4 x Zkittles

GG4 x Zkittles was one of the cannabis plants in my recent grow, so I wanted to share my experience with these seeds for other home growers.

GG4 x Zkittles – short, predictable plants with dense buds.

  • Easy to keep short & bushy – Minimal stretch (plants won’t get unexpectedly tall). That makes these seeds suitable for shorter grow spaces or beginner growers.
  • Dense, top-quality buds – Grows long solid colas, and almost no airy “popcorn” buds. An efficient use of space because the plants get good yields for the size.
  • Flexible harvest – Enters the harvest window and buds continue to improve and get bigger for 2-3 weeks. That gives you more flexibility to harvest buds when you want.
  • “Low surprise” strain – Predictable growth from seed to weed. A classic flowering pattern makes it easy to read this strain as far as when to harvest. Beginner-friendly for learning harvest timing (here’s our book that shows you how to harvest any strain at the perfect time).

Don’t grow GG4 x Zkittles if you want big plants with the biggest yields possible or purple buds (for that, get Purple Ghost Candy)

The sprouted seeds (including two GG4 x Zkittles seeds) – Here’s the full grow journal.

Picked one seedling from each strain, and put them in the grow tent.

The GG4 x Zkittles plant made extremely dense buds. The plant stayed small overall.

Germination: Middling

  • Only 2 of the 3 seeds sprouted.
  • That being said, both seedlings grew well.

Plant Growth: No “Stretch”

  • Grew normally in the vegetative stage.
  • Responds well to being “topped”
  • Didn’t “stretch” much after initiating 12/12
  • Well suited to a smaller grow space.

Happy, bushy plant just before 12/12

Didn’t get that much taller after 12/12

Bud Development: Only “colas”, no little nugs

  • Quick to develop buds, leafy at first
  • Buds are long and solid (“colas”) as opposed to nuggets
  • Buds got extremely dense after several weeks

Flowering day 62 - GG4 x Zkittles buds are finally fattening up!

Yields: Small to Medium

  • Good yield for the final plant size, but smaller plants tend to yield less.
  • Lowest yields in this grow, but still held its weight. If all five plants had grown 2.4 oz it would still be a 12 ounce harvest.

Grower Notes:

  • Give it a little time for the biggest buds to finish maturing.
  • Both of the plants we’ve grown had a surprisingly long “ready to harvest period”. They entered the harvest window quick, but buds continued to improve, harden, and get bigger for the next 2-3 weeks.
  • Kind of nice to have a plant that can be harvested relatively fast and still get good buds, or allowed to mature to greatly increase yields, density, and potency.

Our GG4 x Zkittles plant developed a little faster than average, but very “standard” looking bud development. Which makes it really easy to know when to harvest.

First hairs – day 12 from 12/12

Day 16 – Growing taller

Day 18 – still all hairs

Day 33 – starting to develop

Day 49 – Some hairs start to darken

Day 55 – Still fattening up

Day 59 – Getting close, but still too many white hairs

Day 67 – Beginning of the harvest window

You typically have about two weeks to harvest at this point.

Buds were dense and smelled like a mix of pine and kush, with little “skunky” smell
