LEDs lumens
Grrrowerstarted grow question 4 years ago
is there a method (which does not involve the purchase of a rather expensive device) to measure the lumens present in the growbox? I would like to make sure that the LEDs that I bought have the same performance declared on the package 😕

If you don't have a lux meter, you can try downloading an app that performs this function to your smartphone. it is not 100% reliable but you can still get an idea if you have a good smartphone. in the first days your seedling needs at least 4000/5000 lux to grow so I advise you to approach the lamp and try with your smartphone to help you adjust the distance.

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,
