The bat guano does the heavy lifting for you—steady nutrition over six weeks means less faffing with schedules.

Built from German Black and Baltic White peat, enhanced perlite, and enriched with natural bat guano, it delivers six weeks of slow-release organic feeding alongside immediately available nutrients.

Don't start seeds directly in this—it'll be too hot.

A good root stimulator will help, but hold off the main nutrient schedule. Watch for signs of over-feeding; if leaves look too dark or growth stalls, ease back on supplements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeek 2 onwards (established plants)\u003c\/strong\u003e\u003cbr\u003eOnce plants are past the initial stage, you can begin feeding earlier or immediately if desired. The bat guano will be releasing steady nutrition in the background, so monitor your plants and adjust as you go. Don't be rigid about schedules—let the plant tell you what it needs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePotting technique\u003c\/strong\u003e\u003cbr\u003eNever compact the soil too much when filling containers. Tap and shake the pot so the media settles naturally—over-compacting kills oxygen availability and stunts growth. Fill, plant, soak with pH-adjusted water (target 6.5), and allow plenty of runoff. Make sure the pot base drains freely.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNutrient timeline\u003c\/strong\u003e\u003cbr\u003eThe bat guano releases slowly over approximately six weeks depending on pot size and environmental conditions. Smaller containers will work through the nutrition faster than larger ones.
