What can really be said about nutrients like this. Either they are there or they are not. I've only used these and Humboldt. I prefer Humboldt because of the shape of the bottles, but they are a bit more expensive. The Humboldt bottles line up more neatly on the shelves and have better information on the bottle, but I can't tell the difference between the performance of the two. These nutes are color coded and the Humboldt are not. I add Ginormous also. Good luck :)

I used Flora Bloom when my hydroponic strawberries reached the blooming and fruiting stage, along with Flora Micro and Flora Gro. This is my first year using these, and they work great! I had a bountiful harvest of berries in June, thanks to these General Hydroponics Flora products. I really like it that the instructions for using these fertilizers is right on the bottle, especially what proportions of each to use at the various growth stages.

GH has been around for yrs.. but recently ive noticed a drop in quality control... there are inconsistent amounts of nutrients from bottle to bottle... some bottle are right on others are upto 15% higher or lower than what should be in there. Advanced Nutrients came out with a line called Jungle Juice and is identical to GH Flora line but with much better quality and cheaper!

I am running an indoor farm.
The thing I like is the liquid leaves no residue when the plants consume the nutrients.
My medical plants perform excellent with the simple 2 +2 concentrated mix. Throughout the grow. Changing from veg to bloom at the appropriate time.
Don't even think of using dried nutrients if you are not an expert.

Plants are loving this food and at 1 to 2 teaspoons per gallon of water this will goa long way before I have to buy more. Plants that were not blooming are for the most part blooming now after 2 to 3 weeks and plants that have bloomed and set fruit all summer are now going into beast mode with substantially more blooms and peppers.

I never run nutes at full recommended strength (usually about half - bubbleponics), with the exception of FloraBloom - it contains no nitrogen, the primary culprit in nute burn.
Transpiration and evaporation can lead to nutrient intensification between flushes, which is why I don't run them full-strength.
Thanks, GenHydro!

The succulents on the plates were started in two different methods. The ones on the left were just put on soil and spritz with water- the ones on the right where put in florabloom. They have grown twice as fast. Also the ones in Florabloom are firm, while the others are squishy.

If you want a good priced nute regiment, simple instruction, reliable yields and medical grade potency you use the locus formula. 1 part bloom to 1/2 part micro. Do some research online and go for it. Tried tested and true.
Five stars.

Florabloom + Calmag is all you need for great pepper yields without excessive foliage from too much nitrogen.
Make sure you’re using a 2-0-0 or 1-0-0 cal mag. It’s plenty of nitrogen for hot peppers.

Never had issues with any GH products, floragro is one of the 3 part series of liquid nutrients I have used for over 25 years indoor gardening. Also supplement with Koolbloom for extra boost in flower.
