whats everyone. i have 2 seedling about 6days old under one 75watt cfl and one 75 watt shop light. they r about 3inches tall. wen could i start using my 400watt hps.
um now bc those shop lights suck for them,put it under the hps 18/6 for a month then 12/12, eventhough its an hps,its still better for veggin than shop lights.
