78,600 lumens at canopy, ok for pre-flower and flowering?
dauntlessstarted grow question 4 years ago
I have recently received a lumen meter. Measuring 78,600 lumen over canopy, is that OK? For my other grow, does anyone know how many lumens seedlings need (at about 25000 now) ? I can convert from PPFD or PAR. Educate me! Thanks

about 250-350 Umol or ppfd for Seedlings. 700-1000 Umol Veg and 1000-2000 Umol. Anything above 1000 umol Co2 is recommended.. The idea that having too much light causing damage is a more of myth or poor idea. The light intensity increases transportation to a point where the plant can not keep up with the amount of available light..

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,

amount of sunshine for autos in late flower - open air, outdoor growWe're getting 14-15 hours of strong sunshine a day. Now that I'm late flower, should I move my autos into a spot that will get shade for half of the day? Seems like they may not need to be pounded by this much light/heat at this point and could use more down time.Week 12

additional blurple lightsI also got the blurple lights from my friend. To keep the temperature down I haven't installed them yet and not sure if I will. Will they make a difference if I add them next to the current LED? If so should I wait until the flowering stage or anything like that?

Light pointed at white wall for supplemental lighting?Does it makes sense to have a small 300W COB LED pointed at the white flat painted wall for supplemental lighting?
If I point the light directly at the plants I would surely burn them but have no space to move back.
