Choose the TerraSoil soil kit that fits your growing project. SeedStarter, GrowthCore and BloomCraft have different roles within the layered system. Compare the contents below before choosing an option.
Compare the three kits
Option | Soil layers supplied | Total volume |
Starter Kit (Seed → Growth) | 15L SeedStarter + 15L GrowthCore | 30L |
Complete Living Soil System | 20L each of SeedStarter, GrowthCore and BloomCraft | 60L |
Pro Grower Bundle | 40L each of SeedStarter, GrowthCore and BloomCraft | 120L |
The Starter Kit contains two soil blends and does not include BloomCraft. Choose Complete or Pro when you want all three layers. These are the total supplied volumes, not a required pot size or a rule to use equal layer depths in every pot.
How the layers fit together
SeedStarter — top: the lighter layer for starting seedlings and establishing young roots.
GrowthCore — middle: the main growing layer.
BloomCraft — bottom: the richer reserve layer in the Complete and Pro options.
Follow the setup guidance supplied for your plant and container. For the three-layer options, place BloomCraft at the bottom, GrowthCore above it and SeedStarter on top. Ask us about the proportions for your pot before filling it.
Buying a kit or individual layers
Select your kit in the Choose Your Setup menu on this page. If you only need a refill, buy SeedStarter, GrowthCore or BloomCraft individually.

Preparation and ongoing care
For blends prepared to order, allow 1–2 weeks when ingredients are in stock. Custom jobs requiring specialist ingredients typically take 6–8 weeks. Contact us to confirm the preparation time for your order.
The system is designed to simplify soil preparation, but watering, light, plant choice and container drainage still matter. Monitor growth and nutrition; additional amendments may be needed for demanding crops or when reusing soil. There is no fixed guarantee of yield, germination speed or reuse cycles.
For help choosing a kit, email TerraSoil with your plants, pot sizes and whether you are starting from seed or transplanting.
