If you are trying to propagate Moringa and you live in a cold climate, you may have problems as Moringa needs temperatures above 24 degrees to germinate. A high quality heat mat combined with Small Greenhouse can help you.
You can also use the heat mat to propagate other plants like Chilli once your Moringa propagated.
This heat map has an Electrical certificate of suitability No.6691N Complies with AS3100. Be aware that cheaper imported heat mats may not hold the same certifications.
