## Questions & Answers

**Q: What is the difference between this and  the General Hydroponics Flora combo?**
A: There's probably not much difference except liquid vs powder and big mixing ordeal. I only used Maxigro on all my veggies in coco, soil and Kratky. Maxigro did very well when I adjusted dose as plants progressed. I used faucet water with a 24 hr leaching process and the only leaf discoloration was on my cucumis sativa but that's not unusual. I got male and female flowers with just Maxigrow, no bloom. grew indoors under 2300lum/5000kel LEDs. I did a lot of research since it was my first grow but here's a great YouTube comparison done by Khang Starr. Maxigro did great on all accounts including algae grow.

**Q: will this dissolve in cold water?**
A: Yes, it dissolves readily in cold water.

**Q: Come with feed chart?**
A: No.  The website has  the feed  charts.  There can be some trouble accessing  the chart if you have an agressive fire wall.

**Q: Can it be used in a soiless media?**
A: Yes, we use it for the Kratky method.  Check out YouTube for this easy and inexpensive soiless grow method.
