2x20w will deffo work, i vegged two plants with 2x18w cfl, 1warm 1 cool white, and had 12inches ov growth in the first 2weeks, so it can be done, im not saying u should use that, if u can get more light then do that, more light is better, im currently using 4x18w cfl, 2warm 2cool white, and growth is more than fine, especially on a 24/0 schedulesorry dude, thats not enough man...... i got 10 40w and 5 42w in my box for flowering i wouldnt go with less than 100w for vegging. 2 20w wont cut it for a good growth rate....it will work for the start of veg though
wot im saying is if its only the 2x20 w u got then itl still work but it will take a little longer, go 4 it man.
coz ur using a low wattage u have to keep the light 3inches away from top of plant at all times , also a 24/0 sched is better than a 18/6 if u got low light.
hit the plant with 24/0 for the first 2weeks, then 18/6 for the following 2weeks, then switch them to 12/12, works a treat!!!!!! good luck
