Mycel at $60 for 500ml I don't think it's a lotta money at all, you only need to use .5ml per gal in veg and 1ml per gal in flowering, I can stretch a bottle to last me about 650-700 gallons... and compared to liquid karma is a whole lot cheaper and better IMO.
The single best nutrient additive that I have in my arsenal...I will never grow w/o it again. The quality of my finished product has improved significantly, after using this for the past year. Have seen improvements in all of my bread and butters... that I have been running for years... in overall quality and yield using Sea Green. Trichome coverage, flavors and aromas way up...since the incorporation of this product.
