What kind of light level (lux) during the dark cycle will cause my plants to herm in the flowering stage?
What kind of light level (lux) during the dark cycle will cause my plants to herm in the flowering stage? I am growing in my bathroom (no windows) and I am worried about external light entering. My bathroom has 3 LED (30W) bulbs in, I have removed the 2 closest to my plants.

Switching to bloom nutes and photoperiod changes?
When should I start giving bloom nutrients and stopping the veg nutrients? Also can I switch my light cycle to 24hrs to increase the temps and maximise my yield? Or will this mess with the plants?

78,600 lumens at canopy, ok for pre-flower and flowering?
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

Spider Farmer SF1000 or Mars Hydro TS1000?
What would you recommend between Spider SF1000 or Mars Hydro TS1000? Both seems pretty similar, which one to chose? I’m planning on growing two autos at a time/or one photo, 70x70cm space.

Just wondering if adding sunlight could improve it or makes no difference?
Do you still need to give plants sunlight if they have a tent fan and ac plus led grow lights? I really need to know if after 53 days of 6hours of sunlight daily the plant might be used to the sunlight , although I know led grow lights are like a mini sun inside tent but still?
