When should I switch on the other half of my LED light setup?

Cremostarted grow question 5 years ago

Hi guys, I grow 6 plants in hydroponics in a 4x4 grow box and they are 2-3 weeks old (about 7-8 cm tall). I use MarsHydro TS 3000 LED (450W) which have 2 seperate LED panels. Right now I run only one panel and would like to know when I should turn on the other panel. THX

When you see the first set of true leafs ( 5-7-9 tips) turn it on. Also if using the topping method that would be also time to pinch. If a couple weeks old should be close to that time.

You read my mind again @Fusion :D I was about to ask when the time is ready for topping! Do you mind checking out my pictures from this week and tell me if I should wait a bit more or if it's time to snip 'em? :D THX a lot for your help buddy!

Probleme Mars Hydro tsw2000 Grüßt euch, ich hab ein Problem mit meiner MarsHydroTsw2000. Sie hängt an einer Zeitschaltuhr, fast jeden Tag wenn sie aus und dann nach 6 Stunden wieder angeht, geht eine Seite der LEDS nicht mehr.

Reverse flowering time could I reverse the time when putting into bloom and switching from a 12/12 program? I could turn on at 00:00 and turn off the light at 12:00, because honestly I keep them on during the night and I turn them off at noon and I would like to do the opposite, can I?

Would this be an upgrade or downgrade?Currently using a 400w HPS on a 18/6 schedule for my autoflower. I've just seen this being sold on FB and wondered whether this might be as efficient/better/worse than what I already have Appreciate that it's a 'budget' light, but still looks pretty good 🤷‍♂️🏼
