Iced 'n' Baked

F4 Feminised Automatic
Cycle Time
65 to 80 days from sprout
(3.5 stars) • 10 reviews

Iced ‘n’ Baked is the first Mephisto foray into Gelato genetics and our own Gelauto series. The impact of Gelato clones on the global cannabis community is undeniable; we’ve sampled many of them on our travels around the world and each member of the Mephisto team has a vivid memory of their favourite variety. Gelato #41 (aka Bacio) has arguably become the most popular of all the phenotypes, a well-balanced hybrid strain with extreme trichome coverage, dense flowers with purple highlights, and the perfect blend of creamy, gassy, and candy flavours. And although all of the Gelato phenotypes share some commonalities (dense flowers glistening in trichomes with a complex mixture of aromas of gas, cookie, and candy), we’ve paired each of our selections with a standout Mephisto strain to bring a bit of mountain and lightning to the Gelato world.

What is Meph Math?

Best Mephisto Strains to Grow for Beginners

A question that comes up from time to time by our newer members of the Meph-Heads community is: “What are the easiest strains to grow?” Here are a few of our absolute favorite strains that are both easy to grow and friendly for first-time autoflower enthusiasts.

What Does “Autoflowering” Mean?

You may be wondering, ‘What exactly are autoflowers and how do we differentiate them from other types of cannabis?’ Well, find the answers right here!

What Your Autoflower Will Look Like When it’s Ready to Harvest

 How do we know when an autoflower is ready to harvest? In this article, we are going to review those telltale signs so that you know exactly what to look for when you reach your strain’s harvest window.

Old School Mango Haze - An Award Winning Release (+ Limited Edition drop and a free strain!)

Old School Mango Haze is a strain that has taken us an awful long time to bring to the table; 6 labour-intensive years of development in fact! Check out all of the details of the drop here!

A journey through time, friendships, breeding, barbecues and an interview with one of the OG Originals

So we all know Old School Mango Haze is coming soon, but there’s a lot to digest before we give you the low down on the drop itself. We’ve got a bit of a Mephisto history lesson to go through, a Mephistory if you will, and an interview with our very good friend Karel, the father of Old School Haze.
