iv never tried the tea mix so i couldnt tell u much bout that....but u could try it...why not? id say ud be good on the lights for awhile...but when ur plant gets over a foot or 2 u might need more...start out with those and then judge urself. I mean if u can move ur lights around and can tell that there are areas of ur plant that arent getting enough light u might need more....but hey gettin a work light cost me 6 dollars...gettin a y splitter cost me 1.50 and gettin a 2 pack of bulbs cost me 7 dollars all from home depot. so i mean if u need to add bulbs add bulbs u can tell if u need more light. but to start out atleast for the first month u should b good with those 4 bulbs. i mean i use 12(23w) daylight bulbs for 6 plants and so far its plenty...i may need to get more here in the next month or so once all my plants get bigger but for now its fine...check out my sig and see how i have my lights set up and whatnot. and dont just look at my sig goto the cfl forum and check out everyones setup...thats what i did i got alot of ideas from other people grow setups. the more u look at the more info ull end up having about it.
but basically ur good for now on the lights...u may want to get 1 more socket and another y splitter and mayb 2 more bulbs but at this point i dont think u have to have them. and then when u get about a 2-4 weeks in...jus use ur eyes...move ur lights around u can tell what areas of ur plant arent gettin enough light. its a daily battle to keep ur lights in the right place...jus make sure when u start....keep ur lights 2-4 inches away from ur plant but then when it gets about 6inches to a foot tall move them up to 5+ away so that ur plant can stretch....u basically wanna find that happy medium in between being to far away and to close to ur plants...cus if ur to close ur plant wont get taller it will just grow fatter...and then if u have them to far away ur plant will stretch to much and will end up having fluffier buds and end up with less yield. u just gotta play with ur lights daily and see how it effects ur growth. deff post pics i wanna see how it goes...pm me if u need to otherwise ill check back daily and see how ur doing.
