Red Strawberry Banana Auto brings the famous candy-like Strawberry Banana into Sweet Seeds’ Red Family. Listed as variety SWS90, it crosses an elite Strawberry Banana clone with a specially selected line of Red Poison Auto (SWS39), and around 75% of plants develop red to purple flowers.
The plants follow a mainly indica growth pattern, at 73.5% Indica, 25% Sativa and 1.5% Ruderalis, producing compact red buds smothered in trichomes. Heights stay between 50 and 110 cm (20–43 in), and the full cycle is about 8 weeks from germination.
With THC at 15–20% and around 1% CBD, it delivers a relaxing, imaginative effect, while its purple, pink and reddish resin makes it a showpiece for anyone who presses rosin or makes hash at home.
Strawberry Banana x Red Poison Auto
Strawberry Banana is prized for its fruit-candy aroma and heavy trichome coverage. Sweet Seeds paired an elite clone with a Red Poison Auto line chosen for its purple flowers, so the offspring inherits both the sweet terpene profile and the red color, along with an automatic flowering response.
The result is a fast, compact plant that flowers quickly; the breeder notes mature buds can be ready about 7–8 weeks after the cotyledons appear, with 8 weeks as the typical figure.
Aroma, Flavor and Effect
The aroma is intensely sweet and fruity, the kind that brings back memories of fruit gummies and strawberry-banana chewing gum. Ripe strawberry and soft banana lead, and a surprising hint of walnut and arugula adds a savory twist at the end. The flavor is just as candy-like, smooth and long-lasting.
The effect is relaxing and happy, with a gentle stimulating edge that helps boost imagination and creativity. The body feels easy and loose while the mind stays playful, which makes it a good match for movies, music or a relaxed creative evening.
Its 15–20% THC keeps the experience pleasant and manageable for most consumers.
Growing Red Strawberry Banana Auto Indoors and Outdoors
Keep the lights on 18/6 or 20/4 from germination to harvest; as an autoflower it needs no switch to 12/12. Sow directly into an 11–15 liter (3–4 gallon) container to avoid slowing the short cycle with a transplant.
Indoors the breeder lists 400–550 g/m² (1.31–1.80 oz/ft²). The compact, indica structure suits small tents and sea of green setups, and a light LST session in week two helps even out the canopy. Slightly cooler night temperatures in the last weeks can enhance the red, pink and purple shades.
Outdoors, expect 35–175 g/plant (1.2–6.2 oz/plant). In most US climates you can grow two or more crops a season. Give it full sun and an airy, well-draining soil, and harvest during dry weather to protect the dense, sticky buds.
