When used with GH Flora and GH Flora NOVA + Floralicious Plus for better results Review: I am glad I bought this when I did. The instructions on GH website call for 2 tsp per five gallons during week 7 of bloom but week 7 can be done over for a longer season. This product turned my growing season around, besides having trouble setting flowers on my peppers when it's 95 out in July, the plants responded well to a lower nitrogen and higher Potassium and Phosphate feeding program. The other products from General Hydroponics are also for sale on desertcart like, floranova and floralicious plus, both I deemed necessary. This really turned around my growing season, before I used orchid blooming fertilizer, like 0-54-32 and got lots of flowers but this stuff worked just as well and makes my plants really hardy. The price is offsetting because I bought the whole blooming season line but hopefully the experts at GH will follow through. I have noticed though that the directions on the bottle aren't accurate if your going to be using other fertilizers with this, like the base nutrients, and need to check on the proper amount to harmonize. I got the drain-to-waste (soil) chart off the general hydroponics website and started at week 7. This stuff doesn't seem strong enough though when the plants need to root or bloom, this kind is low on the scale of fertilizers compared to ordering directly the main ingredient, monopotassium phosphate. Compared, plants fed early after transplants (like in february I fed a chocolate ghost pepper monopotassium phosphate) the plants fed the high numbered fertilizer are doing much better. So the strengths of the last two numbers on this are a little low and like buying enough of this to feed 100 pepper plants is outrageous and using a more cost effective program would be better. This didn't exactly turn around the flowering process like monopotassium phosphate (similar to dry koolbloom) because it's just not strong enough. The stuff wouldn't kick in fast enough when I need to get flowers the process takes a while. The change in mesuring nutrients was difficult too because there is now 8 different bottles (floranova,floranectar..) between fertilizer feedings. Review: It’s the first time using this product for cannabis but have heard it gives good results. ## Features - Promotes blooming, increases effectiveness and increases the secretion of fragrance ingredients - Dissolves easily in water, increasing the adsorption of fertilizer - Can be used in any culture area - Promotes blooming, improves effectiveness and increases secretion of fragrance ingredients ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002DV8TBQ | | Amazon Bestseller | #43,881 in DIY, Tools & Garden ( See Top 100 in DIY, Tools & Garden ) #163 in Liquid Fertilizers & Plant Vitalizers | | Brand Name | General Hydroponics | | Coverage | For home gardening | | Customer Reviews | 4.8 4.8 out of 5 stars (2,104) | | Item Form | Liquid | | Item Weight | 1.18 kg | | Liquid Volume | 32 Fluid Ounces | | Manufacturer | General Hydroponics | | Model Number | GL56732537 | | Specific Uses For Product | Hydroponic cultivation | | UPC | 793094014526 877707813437 | | Unit Count | 946.0 Milliliters | ## Product Details - **Brand:** General Hydroponics - **Item Form:** Liquid - **Item Weight:** 1.18 kg - **Liquid Volume:** 32 Fluid Ounces - **Specific Uses For Product:** Hydroponic cultivation ## Images ![Hydroponic Fertilizer GH KoolBloom 946ml - Image 1](https://m.media-amazon.com/images/I/81Wdk9tmy1L.jpg) ![Hydroponic Fertilizer GH KoolBloom 946ml - Image 2](https://m.media-amazon.com/images/I/81vwTELp9mL.jpg) ![Hydroponic Fertilizer GH KoolBloom 946ml - Image 3](https://m.media-amazon.com/images/I/81SmzyvConL.jpg) ## Questions & Answers **Q: which type of general hydroponics should I use to replace Fox farm Big bloom?** A: You would use this liquid KoolBloom the whole time through flower cycle and use the powder KoolBloom in addition with this in the last 2 weeks of flower before a flush. **Q: What is the mix rate per gallon?** A: One teaspoon per gallon during flower. **Q: I currently use the gh flora series. do i use this in place of the boom bottle in that series or do i use this with the flora series and bloom?** A: Use this with the GH flora trio. I cut their recommendations in half, so I use 1/8 tsp per gal week 5, 1/4 tsp per gal weeks 6-8, then 1/2 tsp per gallon weeks 9 & 10. GH also has their nutrient charts on their web site, if you prefer to see their feeding schedules. Hope this helps. **Q: ... Ive heard this Increases the smell of buds immensly ... is this true ??? ... I luv the smells produced and would like to increase the smell and a** A: this will increase the size and potence of the bud bulkening it up i find the smell to be the same with or without a good product i use it always every flower it is part of my feeding schedule ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***S on August 11, 2016* I am glad I bought this when I did.
