5600 kelvin temp or more is best for healthy veg grow. simulating early spring's high blue spectrum. I personaly favor daylight simulant 42 watt 3000 lumens. with this type of lighting your plants will grow sout and bushy, with a very strong, sturdy, thick stem and with the right soil, healthy build of root system. Which is very important to the best soil money can buy, becuase the better soil you have, the easier it makes it on your plants to push through and **** up nutes and water.
Flowering, I think if we all could afford an HPS light system that would be the best right now. All though I have been hearing rumors of LED grow systems. Under that is a 42watt 3000kelvin temp under a soft white glow. simulating the hotter red spectrum shown in late summer and early fall.
your plants look great and normaly healthy. Keep your schedule and routine going and make sure to get more lighting, if you have'nt already. keep it up.:aok:
