1 ounce of water a day??? like a fluid ounce??? that like, 2 tablespoons. theres yer problem. and as long as the pots' not to big for the plant, you can go ahead and saturate the soil. the roots grow like 3 times as fast as the foliage grows in the seedling stage, and you got plenty of perilite in there to keep from overwatering. also, an overall dry medium will contribute to more males.

the first one looks ready to grow!

maybe less heat/ more humidity would help too.

water is life:thumbsup:
