AutoPot Tray2Grow Capillary Spikes – Spike Only Set
The AutoPot Tray2Grow Capillary Spikes are designed for growers using the Tray2Grow system with grow bags or planters that don’t allow easy bottom-feeding.
These spikes pierce the underside of a grow bag or fabric planter, allowing water and nutrient solution to be delivered directly into the substrate from below.
Used in place of capillary matting, the spikes convert the Tray2Grow into a targeted irrigation system that feeds plants evenly and efficiently, without pumps, timers, or electricity.
Please note: this item is purchased to order so extended lead times will apply.
Key Benefits
- Direct substrate irrigation; delivers water and nutrients straight into grow bags
- Perfect for fabric planters; ideal where capillary matting is not suitable
- Power-free feeding; works with gravity-fed AutoPot systems
- Even moisture distribution; reduces dry spots and overwatering
- Easy to install; simply fit into the Tray2Grow tray and position beneath bags
How the Tray2Grow Spikes Work
When fitted into the Tray2Grow tray, the capillary spikes sit directly beneath your grow bag. As the AQUAvalve allows water into the tray, moisture is drawn up through the spikes and into the substrate, feeding the root zone evenly from below.
This method is especially effective for growers running fabric grow bags, framed planters, or heavier substrates where traditional bottom perforations are limited.
Compatibility
- AutoPot Tray2Grow system
- Fabric grow bags
- Planters and containers with pierceable bases
Top Tip: Use Tray2Grow spikes when running fabric grow bags or large planters, and switch to capillary matting when starting seedlings or working with smaller pots for maximum flexibility.
