i am going to set up my new tank, and after reading some threads on other sections of the forum. i have 2 sets of lights (T8's and T5'S). my question is, i want to use toms method and put glosso in for abut 5 or 6 weeks to grow emersed. i will only use the T5's and have them on for about 9 hours a day. but i have a few questions. 1) can i grow any of these plants emersed, or do i have to wait... E.tenullus. P.helferi (those are the only ones i think i can grow as the rest are stems or need to go on wood) but i need some clarification. 2) do i have to cover the top of the tank, with something like plastic or a bin liner to get the greenhouse effect, with it being nice and humid etc. (its 120x40cm (240L)) lastly, is it best for me to go with this method, or should i just go full on and put all the plants in and fill it right up? i think it would be nice t get the glosso to bulk out abit before i put the stems in.
