Thinking about topping up my soil… should I consider something fancier than soil, bat guano I’ve heard, worm casings
What else have you tried so far?
I haven’t tried anything yet.
I like roots organics. For “Top dressing soil”
What’s the grow using currently or usually?
Do you have a nute regimen that your using now?
If you have a large amount of soil to re amend a soil test might help to identify which nutrients you are low in and what needs to be boosted. Without a test I would try to get as much balance and variety as possible in amendments. Gaia 4-4-4 all purpose has a decent combination of ingredients to give a more balanced adjustment.
If there’s any deficiencies visible I would make sure to add more of that specific nutrient, moulders chart is worth mentioning if your playing with nutrient levels
I have a soil test kit actually, I’ll give it a try.
