Brotanical About Me
Hi, I’m Brotanical, an indoor grower with years of experience in controlled environments and NDL/HPS/LED cultivation.
I focus on data-driven grows, lighting efficiency, and plant response under real conditions.
This diary documents a cycle with the ViparSpectra XS1500 Pro, alongside a parallel Vivosun report, allowing objective comparison and structured feedback.
Goals of This Grow
• Evaluate real-world performance of the ViparSpectra XS1500 Pro
• Compare results with Vivosun Level 3 lighting
• Analyze light penetration, stretch, and canopy development
• Document plant health, flower development, and final yield

Brotanical Going fordward well
Viparspectra Performance is great with mol
Brotanical Overall Status:
The Bruce Banner (Dark Horse Genetics) is progressing beautifully. We are currently at the beginning of flower week 5. The canopy is dense and even, thanks to the LST and netting. The trichome production is ramping up significantly, and the plants are showing great vitality.
Feeding & Watering:
I am currently running a heavy feeding schedule to support the "bulking" phase. The front plant is much thirstier than the back two, which is likely due to its high metabolic rate and airflow position.
• Latest Feed (per Liter): 2ml Hesi Bloom, 1.1ml Hesi PK 13/14, 0.8ml CalMag, and 4ml Alfa Boost.
• Observation: The plants are responding well to the PK boost with no signs of nutrient burn so far.

Brotanical Update: Watering & Feeding Log
"Today, I watered the two Bruce Banner 🥦 in the back with 2.4 liters each. The water was pH-adjusted to 6.34. As a preventive measure against pests, I added 1 million SF nematodes to the solution.😤
Nutrient Schedule (per Liter):
• Hesi Bloom Complex: 2.3ml / L
• Hesi Phosphorus Plus (PK): 1.2ml / L
• Hesi SuperVit: 1 drop (as per instructions)
• Plagron CalMag Pro: 0.8ml / L
I skipped the Alfa Boost this time because it tends to lower the pH 🍋further than desired.
Environment & Lighting:
• LED Power: 88% 💡
• Light Intensity: ~730-825 PPFD
• Distance to Canopy: 34cm"
