Hawaiian Rainbows strain review — RS11 × Hawaiian Sherb Cake

A candy-and-dessert cross built for growers who want big yields and real resilience, not just a good story. Here's what's actually in the pack.

Hawaiian Rainbows is one of the current lineup's most requested packs — and once you look at what's actually crossed into it, it's not hard to see why.

The lineage

Two things stand out when you trace the parents individually. RS11 is where the flavor comes from — it sits in the same dessert-leaning family as Gelato and Sunset Sherbert crosses, which is part of why that lineage has become so popular in recent years. The Hawaiian side is where the plant's toughness comes from — Federation Hawaiian genetics are known in breeding circles for handling humid, high-pressure grow environments better than most.

What to expect

These numbers reflect typical results for this cross — actual results will vary by phenotype, environment, and growing technique, as with any feminized pack.

• Terpene profile: candy and dessert-forward, consistent with the RS11 side of the cross
• Potency: 23–28% THC, putting it solidly in the upper range for a dessert-hybrid cross
• Yield: 70–90 grams per square foot — a strong showing for a pack built around flavor genetics
• Flowering time: 63–70 days, a fairly standard window that won't test a grower's patience
• Climate tolerance: notably better resistance to humidity than many modern hybrid lines — a real advantage if you're growing somewhere sticky
• Format: 5 feminized seeds per pack

RS11 brings the candy. Hawaiian Sherb Cake brings the backbone. That combination is the whole reason this pack exists.

Who this pack is for

If you've grown finicky dessert-hybrid genetics before and lost plants to mold or stalled growth in humid conditions, this cross is worth a look specifically because of the Hawaiian side's reputation for resilience. It's also a solid choice if you're newer to growing and want a pack with some built-in forgiveness rather than a genetics-collector strain that demands a dialed-in environment.
