Yeah no disrespect but your lumens output is going to be so low that 2 26w CFL's wont do anything no matter how much mylar you use lol you need atleast 3 above the plant to get one main cola and the bottom 3/4 of your plant will be useless because light wont penetrate the canopy enough to allow flowers to bloom. Also soft white = 2700k color spectrum and bright white = 6500k color spectrum just like you would use mh for veg and hps for flower. You can add the 2700k to the flowering cycle and run both 6500 and 2700k lights at the same time for more lumens and watts.get 2 26 watt which is equivelent to 150watts cfls'. buy some shiny foil or mylar and place it all over the inside of your grow and put a lil fan in there for air circlulation an have a lil computer fan in a whole you place at the top of your box for ventlation and keep your plants watered. (spray your seedlings once in the morning and once at night)(water 1 every 3 days when in veg). good luck
What are 400 watt hps going for id need a complete system
haha go buy those 2 - 26w CFL's and try to grow let alone flower a plant...Jeeze you wonder how many people are actually knowledgable or just give bullshit advice to build their rep and points...okay and how much are you paying for that plus a 26 watt cfl throws out as much watts as a 150 watt bulb plus a 26watt cfl puts out 2150 lumens and with 1 plant that requires only 2500 lumens so with 2 26watt cfls' i think she pop some fat buds out buddy.
