Review: The product is great, if it arrives. Not sure how desertcart manages who gets to sell you the product, but when they picked Grow Green MI to be the lucky vender, I received two out of three gallons and Grow Green MI customer service never bothered to read the tracking information on the shipment wherein the shipper reported that the package was damaged and disposed of. After desertcart took down my review because they find my complaint focused on the misfortune, rather than the fault of the vender, I have now revised my review to specify that Grow Green MI does provide horrid customer service and cannot be counted on to handle a transaction from end to end. desertcart appears to have removed Grow Green MI as a potential vendor of this product, but you should double check who the vender is before purchasing. General Hydroponics makes a great product, but should take care in deciding who is allowed to distribute it. Follow the directions carefully and you will get great results.
Review: I’ve been using the General Hydroponics FloraSeries nutrient system for several grow cycles now, and overall I’m very satisfied with its performance. What I liked: -Complete 3-Part System: Having FloraMicro, FloraGro, and FloraBloom lets me tailor feeding throughout the plant life cycle — from vegetative growth to flowering. -Consistent Results: My plants have shown healthy vegetative growth and good bloom development when following the recommended ratios. -Ease of Use: The directions are straightforward, and the bottles are easy to pour and measure with. -Versatility: Works well with various hydroponic setups, including NFT, DWC, and ebb-and-flow systems. What could be improved: -Requires Mixing & Monitoring: As a 3-part system, it takes a bit more measuring and planning than a single-bottle nutrient — but that’s typical for serious hydroponic formulas. -pH Adjustment Needed: I still needed to monitor and adjust pH after mixing to hit my target range, which adds a step to the routine. Overall: For anyone doing hydroponics — from beginner to experienced — the FloraSeries offers solid performance and flexibility. It’s a trusted staple that’s helped my plants stay vigorous and productive.

## Questions & Answers

**Q: What does 0 5 4 mean? i thought it was supposed to be 20 20 20 for npk ratios.**
A: 0 5 4 means it has 0 percent nitrogen, 5% phospherus, and 4% potassium.  20-20-20 is 20% all around

**Q: Is this suitable for semi-hydroponics? i plan on using leca as the substrate**
A: Yes.  This can be used from straight hydro to soil, by following the recommended procedures.  Semi hydro should probably be similar, dosage-wise, to straight hydro, I should think.

**Q: At what strength should these be used with cannabis?**
A: I use it this way 
Beginning(growth stage)
2tsp green, 1 tsp red, 1 tsp pink
Flowering 
1 tsp green, 1tsp red, 2 tsp pink 
Been using for 2 years

**Q: is this good for marijuana?**
A: Yes it works good.
