Does any devices exist to run 2 bulbs alternatively (like two 12 hrs cycles, one On, the other Off) out of one ballast ?

It is possible to rig two timers in parallel with one ballast. Then you can program varying intensity to simulate natural day light with weaker mornings, intense mid-days, and ramping down evenings.

Irregular light schedule.I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her?
My first thought is that it doesn’t matter much since she is an auto, however I know that plants love balanced environments.Week 3

Hey growmies✌️💚, so I finally have a PAR meter. With all my 3 LEDs on at the lowest setting I reach like 77 umol max. What would you recommend for seedlings that small like in the picture? I saw seedling/clone 100 - 300. So just wondering how much for my little flowers? 😁✌️Setup. Lighting

Is my LED too close or too far from my plant?So this is my first grow and it feels like she’s growing a bit slow. Currently at day 10. Distance was 62 cm. The LED is 100W. Now the distance is 57 cm. I’m wondering if I’m just impatient. Is this distance appropriate? How is the growth looking?Week 2

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions

Lighting cycle for VEG stage. Is 24x7 OK?Hi,
Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED
Thanks,
