I'm currently keeping the lights on about 16 hours aday but the plants are about 2 ft away.They were growing well outdoors from March to about October. I slowly hardened theses 2 plants to more light and I'm wondering if anyone else has had success with clematis under LEDs. I have one Jackmani a Nike Warsaw rooting I'm hoping to sprout and I don't know what type my other one is. Thanks for any tips.Oh and yes the lights are on timers!
