Let’s talk VPD — Vapor Pressure Deficit. Mastering VPD can boost flower size, resin production, water uptake, and nutrient delivery.
Most growers don’t struggle with nutrients… they struggle with humidity + temperature balance.
Post what stage you’re in and what VPD target you use:
• Seedling
• Veg
• Early flower
• Late flower
Bonus points if you share your humidity/temp numbers.
This thread connects perfectly with nutrient troubleshooting happening in the Growers’ Corner right now — your VPD settings may help someone stop over-feeding or under-feeding.
Question:
What’s ONE adjustment you made to your VPD that noticeably improved your grow?
