Time lapse under HID lighting
Demosthenese
started grow question 4y ago
How do people do time lapse with hid lighting? Do I need to set timers to turn off hid, turn on fluorescent and then take the picture? Is there a filter I could buy that eliminates the horizontal scanning lines?

When to flip into flower?
currently midway through my 9th week of veg and am wondering when I should send plants into flower, should I double check sex first? (Feminized seeds) or wait until my screen fills out more? Plants are in 3 gallons pots and I worry that they might get rootbound if I veg Longer.

Tengo un reflector y unos neones TCL para poner mis plantas automáticas a crecer después de la germinación hasta que estén preparadas para estar en el balcón. Pero no funciona. ¿Alguien recomienda una bombilla normal que pueda utilizar hasta que reciba un nuevo reflector? GRACIAS

En qué mejora más watts de luz
En qué mejora que ponga 100w de LED a 30/40cm de las plantas a qué tenga 50w de LED a la misma distancia ? O por ejemplo con 400w de LED a 40/50cm crecerían x(2, 3, 4) veces más rápido?

Light height and intensity
Hello all. Recently I upgraded my lights to 2 mars tsw 2000. I've noticed my plants are growing slowly compared to everyone else's. I have it set at 24 inches 25%. However a mars hydro admin posted 12 inches 75% during veg? Isn't that like 1500 ppfd? I'm so confused.

Light Science
Has anyone watched some Youtube videos by Dr Bruce Bugbee from Apogee Instruments? I find his lectures on lighting to be the most straight forward explanations I have heard yet. I found his vid called "The New 400-750 nm ePAR Range Explained with Dr. Bruce Bugbee" to be eye opening on lighting colours. I have changed my LED's based on a few of his vids. He explains what plants really want and those Burple lights just don't cut it. For those that don't know he is a professor at the University of Utah that legally studies cannabis growth. He takes the science of weed grow to a whole new level.

Heyho So apparently my plant got bigger than I thought. After stretching its only 30 cm from the Mars TS 1000 (Its already on the highest possible position) And I'm running it at ~80% Do you think I can turn it up to 100%? It's always nice to go here Thanks for helping H. G.

LED light recommendation
I am going to need a new LED light to hang from the ceiling. I am looking for a light that has the red/blue spectrum. A dimmer switch would be awesome- the ones I read about that include-seedling, veg and flowering settings sound amazing. Any recommendations out there? Thanks in
