ALright, i started 8 plants under two 40w tube floros (4 feet long). The plants are about 3 weeks old and growing very slowly. They only have there first pairs of leaves, some have a few tiny leaves on them also. Will they be ok for like another week until i grab another 400w hps? The stems are turning like dark red and they are about 4 inches tall. I water them regularly also. I just need to know if they will survive until i grab another hps.
