I wanted something simple, growing is only hobby. My schedule is busy, this is much simpler way, for me anyways, and takes less of my time, than mixing and measuring several different nutrients. I'm using 5 gal dwc buckets, with R.O. water, ph'd at 5.9-6.0. Holds ph well, I don't worry about fully dissolving the nutrients, what doesn't break down when mixed, breaks down on its own, maybe the air disc helps with that. But anyways good stuff, priced nice, and a very simple way to grow. ALWAYS PH! ... show more

    • Works amazing, and the price is great
Very easy to use, with my RO water the ph has stayed between 5.89 and 6.28 at all strengths from 1\8 to the full 6 grams in flower. This is my first grow since getting my script and it has been amazing. Harvest first plant in two days. I did what most people say not to and started multiple strains and only have an issue with one plant having a calmag problem which I blame on the pheno as I have two of the same ww and no other plant has shown the same problem. This appears to work amazingly as a stand alone with the majority of plants but I would recommend extra calmag on hand, a little extra silica never hurts either. This is by far cheaper than any premixed nutes and you can try a sample off their site first and just pay shipping (which is what I did.). The sample is plenty for a smaller run, I have 5 in flower and four more in veg and have about 3/4 of the sample left still...I can only imagine how long this 20 plus lb will last. Only thing I don't like is the nitrogen balls draw in moisture and start sticking together. I have it in an air tight container with silica packs and it still happens so I would recommend pulling out a smaller amount from the large bag and sealing the rest in a food grade bucket with silica packs, only open to refill smaller container and leave sealed the rest of the time. Hopefully that will avoid so much moisture. I read they are changing up their recipe so perhaps moisture and calmag will not be an issue anymore, who knows. Either way it is affordable, easy to use, and works amazing. If your new to growing research everything first (I spent 4 months scouring the net before ever making a purchase.)from strains, breeders, electrical requirements, nutrients, deficiencies, temperatures, lighting, fans, ducting, water ph, Rh, lst, hst, monster cropping, mainlining, reverse osmosis systems etc and you can avoid the majority of newb problems I have read about. I have a lot to learn still but didn't lose any plants and have a MUCH larger yield than I expected for a first run. ... show more

I’ve been using a few of Greenleaf Nutrients’ products for a little while now, and I will say that they do seem to work well in the garden. The bags are a good size and a decent value considering how much fertilizer you get. So far plants seem to like this 1-part fertilizer. When switching from another nutrient program, plants seem to react positively to these new nutrients. They continued to grow well. I think it should be known that these products are made in China as stated on the bottom, typed in very small letters. This may matter to some folks, and it could possibly mean that the makers aren’t as stringent as to what goes into the recipe. Who knows what quality ingredients are in these. If you are consuming your plants in the end, you may want to be careful what you feed them. This company makes it look like it’s made in either Canada or the US, but that’s a little misleading. I actually like the bags for packaging and they haven’t leaked for me. It mixes well and creates a dark color mixed solution for your plants. It doesn’t smell or anything. So it seems to work ok, just not sure what’s in it. Not sure if I’ll continue buying their products, they should be more up front with their customers. ... show more

Good spectrum of nutrients plants love. A little goes a long way. Used a coffee grinder to break it up into a fine powder then added to reservoir with a little extra cal mag. Ladies were praying to the light the whole grow. Later added their Bud Explosion as well. Who wants to be a mad scientist when mixing nutrients right? This is simple and effective. Grabbed an extra bag too so I’m good for years! The Maui Wowie here tells the tale. ... show more
