It may be fine this run, they look fine to me, if you have a humidity meter youll know for sure and they are only like 10 bucks at wallmart for a temp humidity combo. The cfls generally are just ok, nothing great but can do the job. Heat doesnt equal enough light. In winter it wont be hot with double the light that in summer would scorch them with much less. The sylvanna brand leds are the best you can buy off the shelf and put out around 110 lumens per watt and are cheap, same cost as cfls. The main thing that makes the leds better is all the light can be directed where you want it, and the cfls just spray it all over. Id try to just struggle through this run as cheapy as you can then buy a hps and learn to properly cool it with fans and ducting next run. For about 250 you can get a 1000 watt hps, bulb, a cool tube, ducting and a fan. And then youll be able to easily pull 8 oz to a lb every 2 months.
It may seem like a lot of money, but its a investment that will pay off. And spending 20-30$ every few weeks adds up quick. Better to buy once an cry once, then get good reliable results for years. I am not a fan of leds... they cost too damn much and i dont think dollar for dollar you can beat a hps. Its easy to hook up ducts and fans to them unlike leds too.
