ok i guess ill just have to buy myself one of those huge bottles of prime then. also why happi advised to avoid strong lights durring this process. why is that? i currently have a few sprigs of dwarf sag and a hangfull of glosso. should i just use a weak light for this then?
You should be using an adequate light for growing plants if you've already planted...but you'll need to be doing water changes and preventative maintenance and removal for algae prevention. It can very easily take over in the early stages. If you wanted to do an actual fishless/plantless cycle, then you wouldn't even need a light honestly....none of the bacteria that establish in the soil and in the filter are dependent on light, only oxygen and a food source (ammonia, nitrite, organic matter, etc.).
