I just started my plants in seed starters, and it's under a 400 watt hps, will they grow, I've had them there for a day and it looks like they haven't budged
How far away is the light? I probably wouldn't have started them under the HPS, too much light. Maybe buy yourself some cfl's and start them under those for the first week or two if your determined to get them under the HPS asap. Otherwise I'd just use the cfl's for veg. GL and Happy 4/20!
