The Best Autoflower Nutrients: Highigan’s Massive Grow with Cronk Nutrients Bonnie & ClydeUpdated 5 days ago
Discover why Cronk’s two-part Bonnie & Clyde system is redefining autoflower feeding — proven by Highigan’s record-breaking grow.
When it comes to growing strong, high-yielding autoflowers, the nutrients you use can make or break your results.
In their latest YouTube grow, Highigan put Cronk Nutrients’ Bonnie & Clyde Autoflower Nutrient Kit to the test — and the results were incredible.
Their autoflowers, including Fast Buds Gorilla Cookies, Seedsman Blue Dream Auto, and Hella Jelly Auto from Humboldt, grew faster, healthier, and yielded bigger than ever before using this simple, two-part liquid nutrient system made for autoflowers.
Why Autoflowers Need Special Nutrients
Autoflower plants have shorter lifecycles than photoperiods — meaning they move from seed to harvest fast.
That speed demands nutrients designed specifically for autos, not just diluted photo formulas.
Autoflower nutrients like Cronk’s Bonnie & Clyde are built for:
Lower nitrogen levels to prevent early burn
Smooth nutrient transitions from veg to bloom
Consistent EC and pH stability in coco or hydro
“It’s a mineral-based feed specific for autos — just a two-part system. Bonnie for veg and Clyde for bloom. Super easy to follow,” said the Highigan team.
By starting with Bonnie and switching to Clyde when pistils appear, growers can give plants exactly what they need — without overfeeding or lockout.
💧 Highigan’s Autoflower Setup
Highigan grew in a 60% coco / 40% perlite mix using AutoPot self-watering systems — ideal for mineral-based nutrients.
Since they’d be away for more than a week during the grow, they needed a reliable, easy-to-manage feeding system.
Cronk’s Bonnie & Clyde Autoflower Nutrient Kit made that possible.
Quick Setup Overview:
Medium: 60/40 coco-perlite blend
Pots: 4-gallon fabric pots
Watering System: AutoPot four-pot system
Nutrients: Cronk Bonnie (veg) → Clyde (bloom)
Light Cycle: 18/6 autoflower schedule
Even while traveling to Spanabis in Spain, their plants thrived — proof that a well-balanced liquid nutrient programcan deliver stability and growth even when left unattended.
Real Results Using Cronk Nutrients
When the team returned home, the difference was stunning.
| Strain | Nutrient Feed | Dried Yield | Highlights |
|---|---|---|---|
| Seedsman Blue Dream Auto | Bonnie & Clyde | 131 g (4.6 oz) | Frosty, aromatic, strong structure |
| Fast Buds Gorilla Cookies Auto | Bonnie & Clyde | 70 oz wet | The largest auto ever grown on their channel |
| Hella Jelly Auto (Humboldt) | Bonnie & Clyde | — | Dense buds, loud berry terps, bright color |
“Running the Cronk Nutrients… just a beast,” said Highigan. “We don’t know if it was the nutrients or a freak pheno — but the results speak for themselves.”
Even after drying and curing, the bud structure stayed tight, sticky, and aromatic — showing how balanced liquid feeding can boost quality as well as yield.
Why Cronk’s Bonnie & Clyde Is Among the Best Autoflower Nutrients
If you’ve ever struggled with overfeeding or lockout, you know how sensitive autos can be.
Bonnie & Clyde solves that problem by keeping things simple and consistent.
What Makes It Stand Out:
✅ Two-Part Simplicity: Only two bottles — no complicated multi-part schedules
✅ Perfect EC Range: Designed for autoflowers’ low tolerance to high EC
✅ pH-Stable Formula: Reduces drift in coco and hydro systems
✅ Clean Mineral Base: No residue buildup, no salt burn
✅ Autoflower-Specific Ratios: Nitrogen dialed back, phosphorus and potassium boosted for flowering
Together, they form a complete autoflower nutrient kit that even beginner growers can use confidently.
The Best Liquid Nutrients for Autoflowers — Backed by Results
Bonnie & Clyde isn’t just easy to use — it’s also one of the best liquid nutrients for autoflowers because it performs across:
Coco and hydro setups
Indoor tents and small home grows
Fast-finishing autoflower genetics
Highigan’s success shows that a simple, science-based feed can outperform complex programs.
Their plants had rich color, fast node stacking, and heavy, resin-coated colas — without overfeeding or toxicity.
“So far, it’s been working great,” they said. “We like the simplicity of the two-part system. It’s easy, clean, and perfect for autos.”
Pro Grower Takeaways
From Highigan’s test run, here are the biggest lessons for autoflower growers:
Simplicity = Stability – Autos love consistent, balanced feeding.
Watch EC Early – Start mild (around 1.2 EC) and adjust gradually.
Switch to Clyde Early in Flower – Don’t wait too long after pistils show.
Let Plants Self-Regulate – Use systems like AutoPot to avoid overwatering.
Stay pH Stable – Cronk’s balanced formula minimizes drift and lockout.
Beyond Autoflowers — Exploring the Cronk Lineup
Highigan also teased upcoming tests using other Cronk Nutrients lines:
The Classic Line (Grow, Micro, Bloom) for photoperiod plants
The PuurOrganics liquid organic range for eco-friendly feeding
“We’re going to keep running these nutrients through the paces. So far, we’re impressed.”
