the larger one was planted 3/12, the other 2 on 3/18... the germinated for 2 days before i put them in soil... i'll put them on 16/8 and pray my dog learns how to use a fire extinguisher. i dont plan on using the t5s for much longer, but the area that the hps is, even with the fan and ventilation, makes me nervous because of its weight... my only real concern is if something happened and my dog was stuck in her crate... (im such a good mom!) thanks for you help!
