THCA Runtz Auto captures the exotic flavor and visual appeal of the original while delivering a fast, discreet, and compliant autoflowering experience. It’s perfect for growers seeking quality and speed without compromise.

Expect a strong candy aroma with notes of tropical fruit, sweet cream, and citrus. As it ripens, a hint of gas develops underneath the fruit-forward profile.

All orders are shipped in plain, unmarked packaging to ensure a discreet delivery.

This autoflower stays compact, usually 60–90 cm tall. It’s ideal for grow tents, balconies, or low-profile indoor setups where space is limited.

Expect a full cycle of 9 to 10 weeks from germination. It starts flowering automatically around week 3 without any light cycle changes.

Yes, it performs strongly in coco and hydro setups like DWC, provided pH and EC are carefully managed. Growth tends to be faster and yields slightly higher.

Yes, it’s user-friendly. It doesn’t require advanced techniques, tolerates minor mistakes, and delivers top-shelf results with basic care and good lighting.

Buds are round, dense, and heavily frosted. You’ll see bright green tones with lavender streaks, orange pistils, and a thick coat of glistening resin.

It’s great for growers who want a fast, flavor-packed cultivar with big visual appeal—especially those operating under THCA-focused compliance or seeking rapid turnover.

Definitely. Its short size, quick lifecycle, and manageable early odor make it ideal for discreet indoor or outdoor setups.

It means the plant is autoflowering and bred to be compliant with THCA-focused legal standards—producing flower with structural and resin traits aligned to those markets.

An 18/6 light cycle (18 hours light, 6 hours dark) works well from start to finish. Some growers run 20/4 for slightly faster growth, if temperatures allow.

Yes—gentle low-stress training (LST) early in the grow helps spread the canopy. Avoid topping unless done in the first 10–12 days due to limited recovery time.

Always start in your final container—typically 3 to 5 gallons. Autoflowers don’t respond well to transplant shock and need consistent root development.

Yes, especially in warm, sunny conditions. Its short cycle makes it perfect for quick outdoor runs or multiple harvests per season.

Use a light, well-aerated soil mix with good drainage. Organic-rich substrates enhance terpene expression and promote healthy, balanced growth.

Water when the top inch of soil feels dry. Autoflowers do best with consistent moisture—avoid extremes like overwatering or drying out.

Use a light vegetative feed early, then switch to bloom nutrients rich in phosphorus and potassium by week 4. Supplement with cal-mag if using LED lights or coco.

Yes, it thrives in organic systems. Living soil, dry amendments, and compost teas can enhance flavor and improve post-harvest smoothness.

Maintain 22–26°C with RH around 55% in veg. In flower, drop humidity to 40–45% to prevent mold and promote resin development. Good airflow is key.

This grow kit includes premium-quality components, such as a germination plug, two compost mixes, high-quality organic nutrient blend, and a biodegradable container, ideal for starting strong without extra purchases.

Yes, each kit’s seeds are third‑party tested and include a Certificate of Analysis for quality and reliability.

Yes, the kit includes two premium AUTOFLOWER seeds chosen for their reliability and ease of growth, making the experience smoother for new growers.

Everything is pre-selected and portioned, no need to guess soil type, nutrient ratios, or container size. Just follow the guide and get started.

Orders are typically shipped within 24 hours and arrive within 5–7 business days depending on your location.

Yes, the included materials are suitable for both environments. Just make sure your plant receives enough light and is protected from extreme weather if grown outdoors.

Yes, all seeds included in this kit are autoflowering and feminized, so they transition to flowering automatically without light changes.

Absolutely. It’s compatible with most small to mid-size grow tents and fits well in 2×2 or 3×3 setups.

While designed for autoflowers, the grow kit can still support photoperiod seeds if you manage the lighting schedule accordingly.

Most autoflowers are ready for harvest within 10–12 weeks from germination, depending on the strain and growing environment.

This kit saves you the time, research, and risk of incompatible materials. Everything is curated to work together, helping you avoid common errors.

A full-spectrum LED grow light is recommended to replicate natural sunlight and support each growth phase efficiently.

Light pruning is helpful for airflow and focusing plant energy. Remove lower leaves and branches that don’t receive much light.

The kit is compact and fits well in small grow spaces like closets, tents, or window areas. A few feet of vertical clearance is enough.

Check the top inch of the soil, if it feels dry, it’s time to water. Avoid overwatering, which is a common beginner mistake.

Temperatures between 70–85°F and humidity around 40–60% during growth are ideal. Lower the humidity slightly during flowering.

Look for green, upright leaves and strong daily growth. Yellowing, drooping, or spotting may signal overwatering or nutrient issues.

All grow kits are shipped in plain, unbranded mailers with no mention of contents or strain names on the outside.

Begin light feeding once your plant develops its second set of true leaves, then follow a steady schedule through flowering.

No transplanting is necessary. Start your seed in the germination plug and place it directly into the final container included.
