answered grow question 10 months ago
It uses 385nm and 365nm leds. May slightly increase flavours and smells but beyond that will produce absolutely no stress response.

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?

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?

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.

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
