ASG created its own fertilization kit! This specially formulated fertilizer is based off of LieBig's Law of the Minium, and the redfield ratio. It will provide everything your plants need to keep them happy and healthy. 
 
How much fertilizer comes in these kits?
Instead of buying a new ASG Fertlization kit, all you need to do it buy a refill pack. The idea behind the refill packs is that you'll get enough of each compound to make X amount of refills. This prevents you from running out of a single compound midway through refills. Refill packs come in 4 sizes depending on how much you need:
 
Small - Good for (1) refill of our 500ml bottles (.16lbs of fertilizer)
Medium - Good for (5) refills of our 500ml bottles (.84lbs of fertilizer)
Large - Good for (10) refills of our 500ml bottles (1.69lbs of fertilizer)
XL - Good for (20) refills of our 500ml bottles (3.39lbs of fertilizer)
 
What does each refill kit come with?
The kit comes all the micros and macros needed to make X amount of refills. Simply follow the recipie on the bottle, add water and shake! BAM, you have more fertilizer! 
 
What the differece between these pack and the ASG Fertlization Kit?
The ASG fertlizatoin kit comes with 2x 500ml dosing bottles, a funnel, and enough fertlizer to get you started with one refill. Once you use up the compounds that come with the kit, you can buy these refill packs to make it even more cost effective! You can check out the ASG fertilizer kit here.
