In this week’s Grow Guides, we dive into four key topics that every home grower will run into at some point:

1. The best way to store cannabis after harvest – how to preserve potency, flavour, and freshness with proper jars, humidity, and storage conditions.

2. CO₂ in the grow room – when it’s worth it, how to use it safely, and whether home growers really need it.

3. Defoliation pros and cons – how to improve airflow and light penetration without stressing your plants too much, and the best timing for leaf removal.

4. Preventing and fixing nutrient lockout – spotting the signs, correcting pH, flushing properly, and keeping your plants feeding happily.

We also have some great questions in listener mail, including a chat about what F1's and F2's are when it comes ot cannabis genetics, and what books we recommend for new growers.

Packed with practical tips and grower-tested advice, this episode will help you avoid common mistakes and get the very best from your cannabis plants.
