google estimative index. Use the methods described in that to make your plants grow "fast". Alternatively, the fastest growth method out there for most aquatic plants is to grow them emersed. Google that too.okay so what would happen if I was to supply substrate nutrients, and water column nutrients then pour the seltzer water into a sealable glass container and hopefully get some accelerated growth. I am going to be giving this a try either way to see if will help get a plant growing fast or not. I would like any imput to have all the facts before i give it a try. maybe if this does not work just dosing high nutrients and light with high co2 to get the fastest production. If anyone knows a fast way to grow plants give me a type. I want to grow plants fast to be able to harvest them for replant in some of my breeders.
