3200k my personal or 5000k a mixture of both would be Ideal I don't know why you would want to only chose one though. This is all LED based I assume are you counting MH bulbs they can be very good for vegative growth just expensive to run.

When did the flowering start?
The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?

dli 40x40 growbox lamp distance problem
hi guys, I have a ts1000 at a distance of 50cm they tell me to lower it to 40cm but the dli would greatly exceed (60 dli photone) the recommended threshold of 40/45. Having a 40x40 growbox, in your opinion, at what distance should I keep the lamp?

Light recommendation
what led light would you recommend for a Secret Jardin DS150W (77x150x200cm)? It need to have a remote driver and be full spectrum. It could also be 2 lights.

Sorry hat the question earlier before but I'm new here so I dont know how to undo the solved quesion status. The LED has about 300W and I want to dimm it. not simply turn it on/off. Preferably with some kind of integration in home automation systems like Home Assistant. Thanks :)

First grow. Growing autos from meph in a 3x3 tent. They are in the w/3 of flower. On 24 hr light.(Accidentally) having a heat wave in my area and can't keeps temps down below 80-85. Will it hurt anything to switch to 18/6 now so I can have lights off when it's hottest part of day

Booster light did not turn off during night time

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.

Got a Mars Hydro TS600, will it do alright?
My plan is to grow only 1 plant, in a 40x40x120 tent. I know the tent is pretty small but hopefully i can do some training on the plant to grow wide Will the light do until the end? 100wats, but no light dim possibility. Currently growing seedling at 13 dli at 60 cm

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

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?
