There is Mycorrhizae and then there is Synergy!
This product is one which has been engineered for Cannabis and if you talk to people who have tested it and use it, you will likely hear how much they believe in it.
Arbucular Mycorrhizal Fungi AMF stimulates growth and productivity in the majority of plants on our planet and they also directly help improve soil conditions.
A 140g container will amend up to 560L of growing media using a rate of 1 gram per 4 Liters of soil.
At Transplant 1.5 – 2 gram per 4 Liters of media. This method is best accomplished by dusting the transplants rootball prior to setting it into the new container of soil.
Top Dress 1 gram per 4 Liters of media every 2 weeks throughout the entire life cycle of the plant. Work into the top inch of soil and water in.
You can also directly mix Synergy with water and water plants as normal. The key thing to remember when doing this is to keep bit properly mixed into the water. If you set the container down at all, make sure to agitate it prior to pouring it into a plant pot.
This product is not cheap but it is a superior product which can dramatically increase the volume of finished product.
While I like and frequently use the Myke Brand Mycorrhizae, it simply does not perform like the Synergy does.
Because of a short conversation recently had with someone I thought this was a good time to toss this post out.
