Pros: Effective, easy-pour spouts, understandable mixing chart
Cons: Synthetic, cost
Emerald Harvest's 3-part nutrient system is very easy-to-use. The mixing chart on the back of the bottles are easy to match measurements (mL) and most importantly understand. I have not had any issues with plant loc-out while following the schedule exactly. The effect I have noticed is superior plant development as compared to traditional organic gardening; which is no surprise.
The MSDS sheets are easily available for download on Emerald Harvest's website. After reading the MSDS sheets, I will recommend wearing re-useable gloves while handling & mixing. The ingredients contain mostly nitrates with some urea in it which can be an irritant to some, hence the advice to wear gloves.
I have used this system in conjunction with a root probiotic (review to come) and some homemade worm leachate. All together with superior genetics will result in heavy yields and a simple growing season.
This is an on-going review because this product is currently in-use. I will update this post after harvest for a full report on this product's effectiveness into final stages, as well as any issues/alterations that may come up.
