Hey there... I'm a newby too! 1st time growin ANYTHING!!! I'm having some trouble also but I'll get to that in a min! As far as your light situation...I went to Lowes and bought a 300 watt cfl bulb and it only uses 65 watts! It screws in like a regular bulb and I got mine hanging from the top of my smallest grow space! It measures about 5" or 6" long and it puts out 3900 lumens. I also have the entire area covered from side to side with this bubble wrap that is lined with Mylar that they also sell at Lowes! It was like $14 for a 24" x 25'role! I've read up on it and its supposed to reflect light real good! I got a few seedlings in that area and they're doin pretty good! They're very young so I'll update on their progress. I know that they stretch out to get good ligh source so maybe if you used that bulb and put it as close to the plants without burning them, that might stop them from stretching so fast! That might help you! Like I said.... I'm a newby too, so I may be wrong! But it seems to be working good for me so just wanted to share that info with you to see if it helps you out! WOW.... LOL! Just smoked a fatty so sorry if I'm rambling too much! Now my problem is different... I have another grow area and I'm right around the same timeframe as you! I have 4 seedlings that are about 2.5" to 3" tall and I have all 4 of them set up in a DWC! Fortunately I was able to find a 250 watt MH on Craigslist for $50. I've had them in the DWC with nutes for 3 days now with the light about 5" from the top of them and they are not growing for s#*t! I don't know if I have the light too close or what but I thought they'd do more by now! I also started a thread with better details of my setup so if anyone who reads this has info please feel free to help out! Anyways... If you do decide to get that bulb from Lowes then you should probably invest in that bubble wrap too! Hope I helped! Good luck!
