Perfect for serious gardeners aiming for maximum yield and sensory impact. ## Description Product Description Liquid Kool Bloom is a is a bulking agent that goes way beyond other bloom boosters. Enriched with stress reducing vitamins and nutrient transporting acids, it promotes heavy production of essential oils, fantastic flavors and increases fruiting and flower development. Liquid Kool Bloom should be used at the start of the reproductive cycle initiating larger, heavier fruits and flowers. During the last two weeks, use dry Kool Bloom for an additional bloom boost and to facilitate ripening. Some sizes may not be stocked in all locations. Directions Use Liquid Kool Bloom at the start of the reproductive cycle to initiate larger, heavier fruits and flowers. During the last two weeks, use dry Kool Bloom for an additional bloom boost and to facilitate ripening. Safety Warning Keep out of reach of children and pets. Avoid contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of water. Store in a cool, dry place away from heat sources and open flames. Do not use near food or feed areas. Always wear appropriate protective clothing and gloves when handling. In case of ingestion, seek medical attention immediately. Review: Is what it says it is - Can't wait to get through my transition stage an start blasting my plant with some extra PK Review: takes forever to start blooming - 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. ## Features - Encourages abundant flowering - Facilitates ripening in annuals - Boosts production of essential oils and fragrances ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B001IMJCXK | | Best Sellers Rank | 439,049 in Garden (See Top 100 in Garden) 1,644 in Hydroponic Nutrients & Additives | | Brand Name | General Hydroponics | | Coverage | Medium | | Customer Reviews | 4.7 4.7 out of 5 stars (3,012) 4.7 out of 5 stars | | Global Trade Identification Number | 00793094014540 | | Item Form | Liquid | | Item Weight | 13.5 Pounds | | Liquid Volume | 9463.53 Millilitres | | Manufacturer | General Hydroponics | | Model Number | HGC732539 | | Number Of Items | 1 | | Part Number | HGC732539 | | Specific Uses For Product | Gardening | | Unit Count | 1.0 count | | Upc | 793094014540 | ## Product Details - **Brand:** General Hydroponics - **Item weight:** 13.5 Pounds - **Item form:** Liquid - **Liquid volume:** 9463.53 Millilitres - **Specific uses for product:** Gardening ## Images ![General Hydroponics Liquid Kool Bloom Fertilizers, 1-Quart - Image 1](https://m.media-amazon.com/images/I/81Wdk9tmy1L.jpg) ![General Hydroponics Liquid Kool Bloom Fertilizers, 1-Quart - Image 2](https://m.media-amazon.com/images/I/81vwTELp9mL.jpg) ![General Hydroponics Liquid Kool Bloom Fertilizers, 1-Quart - Image 3](https://m.media-amazon.com/images/I/81SmzyvConL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can you use kool bloom with ocean fox farm soil** A: Yes!
