Money, huh? I hear you loud and clear...... that's why (lack of....) I got into this in the first place! Welcome to capitalism - Good thing God made flos for folks like us....... I started some plants outside and brought them in (how cruel!) under flos. At first they grew even faster, I think because the weather had kind of sucked, overcast and rain...) then I noticed that they (12 plants, 3 strains, coloring effects were the same in each plant, I belive they outgrew the available lumens but who knows?) were getting VERY dark, an allmost black, in the leaves but all new growth came in lush and green, then shaded dark. I was using two Phillips 48" "Daylight Delux" 40 watt, 6500k, 84 CRI, 2325 lumens (each) in a foot wide shop light fixture. The plants all fit lined up in a single row down the center of the light. Well, after a trip to Home depot I returned equipped w/ another shop light fixture and two more bulbs. This time around I got the Phillips "Natural Daylight" 40 watt, T12 base, 5000 k, 92 CRI, 2200 lumens (x2) bulbs to round out the "Delux" by putting the two fixtures together. I have read that the T10 base lamps have a 15% greater output than the T12 base bulbs so keep that in mind too...... the two Daylight bulbs (visualy brighter) are now in the two "outside" slots and the Sunshine bulbs are in the center. I also picked up a bag of nylon cord while I was there to hang the fixtures with and found that if you push the sting down the two "inner" rolled edges of the fixture you can use it to pull and hold them together. I'm going back (yet again) to get two lenghts of dowel that I will replace the rope and use them to pull up the center slightly to focus the light on the plants a little more. I'm pretty happy with the results so far, now my plants are nice and healthy and look great and the growth is good! The whole thing cost me about $75.00 but if your only doing two plants then the same lights and a 4 bulb 2 foot fixture should be pretty cheap......... Hope this helps.........Oh, I would think that they (your seedlings) would be out by now! 95% of my seeds are sprouted and up (in soil) in 2-5 days! Seeing that yours were sprouted before they even hit soil I would think by now you'd be handing out cigars...... I don't think lighting is really a factor, until they break, they'll sprout in the dark. At this point it's all about H2O and tempature.... PLEASE tell me I did'nt miss anything......
