The Sweet Monster Mix® by Sweet Seeds is your gateway to elite photoperiod genetics, combining Monster Maker® and Mental Rainbow F1 Fast Version® in one exclusive pack. Expect high THC, complex terpene profiles, and heavy resin production from these two connoisseur-grade strains.
So many seed packs promise big effects and bold aromas, but deliver average plants with forgettable tastes. You follow the guides, but end up with weak yields or confusing phenotypes. It’s frustrating when your grow doesn’t match the hype.
Because most seed mixes are designed for beginners, not true enthusiasts. They use outdated genetics, offer low THC potential, and lack aromatic depth. Worse, some don’t even specify whether the plants are photoperiod or autoflowering — leading to wrong setups, poor training, and wasted time. You start doubting whether premium genetics are even worth the investment.
This isn’t a random combo — it’s a curated experience for growers who demand more. With Monster Maker® and Mental Rainbow F1 Fast Version®, you get two photoperiod powerhouses bred for potency, structure, and terpene complexity. No filler, no confusion — just elite genetics that perform exactly as promised.
The Sweet Monster Mix® gives you two seeds each of Monster Maker® and Mental Rainbow F1 Fast Version®, individually packed for freshness. You’ll experience intense citrus-diesel and tropical-mango aromas, THC up to 25%, and vigorous, resin-drenched plants. It’s designed for growers who appreciate genetic innovation and sensory depth. What it doesn’t do: it’s not for beginners seeking autoflowering simplicity or low-odor grows — these are expressive, high-terpene strains that need carbon filtration.
Whether you're chasing flavor, yield, or speed, this pack has you covered. Here’s how to get the most from each strain:
Quick overview: photoperiod combo · Sweet Seeds · ~8-week flower · medium difficulty · ideal for indoor SCROG or outdoor in warm climates.
Safe start: Germinate in a moist, dark environment at 22–25 °C and high humidity.
Directed growth: Maintain stable conditions and encourage strong branching.
Flowering by stages: Optimize conditions for maximum resin and yield.
Harvest, drying and curing: Preserve terpenes and potency.
No, both Monster Maker® and Mental Rainbow F1 Fast Version® are photoperiod strains. They require a change in light cycle to flower.
They thrive in warm, Mediterranean climates. In cooler areas, grow in a greenhouse or ensure harvest before cold, wet weather sets in.
F1 Fast Version® are photoperiod hybrids with accelerated flowering, not autoflowering. They offer faster results without the genetic limitations of ruderalis.
Use organic soil, avoid chemical nutrients late in flower, flush properly, and cure slowly to preserve volatile terpenes.
It’s best for intermediate to advanced growers due to high odor and training needs. Beginners should start with autoflowering varieties like those in Autoflower Seeds.
I’ve seen a lot of hype in the seed world, but this pack actually delivers. I was skeptical at first — two high-terpene photoperiods in one mix? But after growing both, I’m convinced. Monster Maker® hits hard with that diesel-citrus punch, while Mental Rainbow F1 Fast Version® is like a tropical vacation in bud form. The resin production is insane — gloves are mandatory during trimming. I ran them under 600W HPS with SCROG, and both responded perfectly. No stretch issues, no mold, just dense, frosty colas. The only downside? The smell. You’ll need a serious carbon filter. But if you’re a grower who values flavor, potency, and elite genetics, this is a must-try. Not just another mix — it’s a statement.
