Lights
Hi guys! What light should I get? The viparspectra xs1000 or the marshydro ts1000? I intend to grow in a 2x2 space. Would the viparspectra be as bright as the marshydro because its more efficient?

Is this MarsHydro light the best choice for my 4x4?
Is the MARS HYDRO Smart FC-E6500 Bridgelux 680w the best option to use for my 4x4 tent. Will be doing 9 CBD auto flowers as a hobby. Thankyou community!

Lux Meter and Hydroponics
Who has experience with using LUX meters to position lights in various stages of hydroponic growth. I feel I am giving mine too much light, based on the readings, but don't want to pull them back. Currently 10" from the plants.

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?

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, Mr.STM

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.

End week 3 Flowering LED Distance
Hello folks First Grow My LED 190 Watt is currently 35cm away from the tallest plant. Heat is no problem 23C on the top plant Is it ok to leave the LED so close or should it be further away? I read conflicting opinions on the net. Flower = less light vs Flower=max light

Far red light
What do you think of additional lighting with Far red? I find the subject very exciting. But when is it best to use it 1-2 hours before and after the main light or better all night or 24 hours?
