• DIY EI Liquid Fertilizer.
• EI dosing method.

• Imported from USA.

Want to dose ferts but the cost of liquid ferts is too expensive??? Dont want to go through the hassle of mixing dry ferts yourself??? Then this is for YOU!!!!!! What you get- 2x 500ml dosing bottles(1x Micros, 1x Macros) 3 sets of fertilizers packets(so you are essentially getting enough to make 1500ml of both micros and macros) It will be shipped without water, all you will need to do is add 500ml of RO water to each bottle. When the solution in each bottle runs out, simply add the refill packet to the appropriate dosing bottle and add 500ml of RO water and you are good to go again. Dosing Instructions: Add 5ml per 20 gallons of water for each the micro and macro 3x per week on alternating days per the EI dosing instructions. How long will this last me?? 20 Gallon tank- roughly 2 years 40 gallon tank- roughly 1 year 80 gallon tank- roughly 6 months and so on...
