Fluoro and LEDs togetherIn addition to the 24W T5 Fluoro, I will be adding an 80W LED Lamp 12" from the tops. This lamp has 3 spectrum settings: Red&Blue, Warm White, and all 3. Which setting is best for veg and how will it affect the plants by having both types of lighting? ThanksSetup. Lighting

Effect of light only? Really?These girls same strain (strawberry cough photo), born on same day, same medium same feeding except the one on the right was removed from the light about 3 weeks ago and put outside. I thought dark green from nutes, seems the light alone makes such a difference? 45 watt LEDSetup. Lighting

If I move 3wk old S.Diesel & Critical from 18hrs💡indoors to outdoors where they'll get +/-11hrs direct🌞. Is there still a risk of them going into flower even though they're still babies? I really don't want this to happen. They'll be in the woods so no chance to add extra light6y ago

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?Setup. Lighting
