You can make growing as simple or as complicated as you wish. Here are some basics for fertilizing your outdoor cannabis grows that work well for us.

Pre-Planting Field Amendments

All-purpose dry amendment, such as 5-4-3, 5-3-2, or similar.

For large scale growers, use between 500 lbs and 2000 lbs per acre depending on spreading technique and planting date.

Feeding Seedlings in the Greenhouse

We use all-purpose fish / plant based liquid fertilizers, such as 5-1-1, 4-3-2, 3-3-3, or similar.

Use at half strength after week 2 of plants being above soil, then work your way up to full dose if plants do not burn.
