well in all anything that is in the tank is gonna be another place for bacteria to rest and grow, but as far as speeding it up, maybe somewhat, but nothing out of the ordinary, if your plants were in a previous cycled tank they already have benaficial bacteria on them and yes this does help speed up the proscess
thats like saying I add gravel and rock from a previously established tank to a new set-up.
plants absorb ammonium, nitrates and
phosphates. Plants also assimilate other undesirable substances, such as
metals, from water helping to improve water quality.
so when you star the cycle you don't have too much of ammonium in the water.
