    Was very different than liquid or powder I had used in the past indoors. Works for in and out growing, simple, effective, clear directions. Great work!

    Mike was in contact with me right away, answered all my questions. I got the bags super quickly actually, before the rest of my supplies. I haven’t grown from seeds or outdoors on my own before so it’s a learning experience anyways. I had questions about seeds and the balances and how to get the most accurate PH readings, all simple to use. Seem like great products, but because Mike was so wonderful, helpful, and personable I will be supporting Reefertilizer for all my growing needs. THANK YOU MIKE! haha 🙂 So far everything is going (and growing) well. I did chop a baby’s head off… it was a light-reaching situation I corrected… but had one casualty. I haven’t transferred out of starter pots or used the fertilizers post start… but I have faith! I found the assistance, guide, and people ideal so go with them! 🙂 Happy growing, stay well!
