You would really need to aquire light intensity meter. Photone app let's your phone work as one on the beta version anyway. Then you will just have to test at different intensity amounts. Heat is also to be considered in extended hours of operation.
I always keep my light at the top and just use the intensity dial to change. Because you do want a good low 80's F in the grow space while operating. If plants are smaller I prop them up on crates or whatever to move them closer to light if needed.

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

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,
