Frequently Asked Questions

Is Rainbow Apples suitable for beginners?

While it is relatively easy to manage, its vigorous growth and high nutritional needs make it better suited for growers with a bit of experience. However, if you monitor your pH and don't overfeed, beginners can still achieve fantastic results.

How tall does this strain get indoors?

Indoors, Rainbow Apples typically reaches between 1.00 m (3.28 ft) and 1.30 m (4.27 ft). We highly recommend using LST (Low Stress Training) or a SCROG net to keep the canopy even and control the stretch.

What kind of effects can I expect?

With THC levels hitting up to 30%, expect a fast-acting, cerebral rush that boosts creativity and mood. It is a fantastic daytime or social strain, but pace yourself if you have a lower tolerance!

Personal Experience of Pevgrow’s CEO (Alan)

When I first popped these Rainbow Apples beans, I knew Grand Cru Genetics had created something special. Before starting, I made sure my carbon filter was fresh—and trust me, you'll need it. The Z-terps start screaming halfway through flower. During the veg phase, I topped them twice and set up a SCROG net. They stretched beautifully during the first two weeks of 12/12, filling out the canopy perfectly.

During the bloom cycle, I pushed the EC a bit higher than usual, and she took it like a champ, stacking dense, frosty colas. After a 10-day flush and a slow 14-day dry, the results were insane. The flavor is a crazy mix of sour citrus and sweet baked apples. If you are hunting for elite feminized seeds that deliver both commercial yields and connoisseur quality, this one is a permanent keeper in my mother tent.
