wild plants vs ours
there is a lake here in mumbai where i get my plants, hornwart, anacharis, duckweed etc. man you guys should have seen the hornwart i scooped up from the lake it was like 3-4 inches wide and super dense, dark, and several feet long. it was beautiful! in my tank, the hornwart grows, yes, but like 3/4" wide and a light green. anacharis forget it, even after flourish its back to transparent and brown growth again. in the lake the anacharis was brown from dirt, but growing strong anyways.
my point is i'm shocked at what a gigantic difference is between the tank and lake. i mean the lake here is teeming with filth, natural and unnatural (its horribly polluted), and wildlife. but does filth explain it? also, the myth that tank size affects fish size, does that apply to plants? i dont see how it could but as you can see, i don't really know much!
