Add on lightingHey Growdiaries. I’m about to start my 2nd grow but I’m not happy with my Viparspectra 300 for flower. I want a cheap add on for the flower stage? CFLs look like a cheap, low energy use, add on as I’m only growing two plants in a small w3xd2xh3 ft tent. Any advice plz & 🙏🏼Setup. Lighting

Mars hydro 600 lights not going fully outHi everyone
I'm having issues with my LED mars hydro 600w when the timer is going to 'off' the lights are still very dim, with the plant being a photo period I'm worried the dimmed lights won't let the plant sleep and shock it or keep it in veg. Has anyone had this issue?Setup. Lighting

Good T5HO flower combo, 3000K and PureBloom? http://www.growagromax.com/products/t5-grow-lamps/t5-pure-series/agromax-pure-bloom-t5-high-output-grow-lamp/Thanks to all for your great advice! This is my first grow, currently in veg wk 5, using 8 x 6500K, 4’ T5HO. Flipping to flower in 2-3 wks, will use 4 x 3000K tubes and planning to get 4 AgroMax Pure Bloom tubes. Is 50/50 mix of 3000K and Pure Bloom a good combination of light?Week 5

Light came on for about 30 seconds about 3 hours into the dark cycleSo Im 3 days into 12/12 and I bumped my timer last night and my light came on suddenly during the dark cycle. I immediately shut it right back off. Was I wrong in shutting it back off right away? Should I be worried about anything?3y ago

Lux Meter Apps on SmartphonesWhat are your thoughts on Lux meter apps? The app on my Samsung Galaxy S10+ is showing 16,600 Lux at the tops of the seedlings, and converting that to a rough PPFD shows 222.55/umol/s/m². Reading more, 15k-45k Lux and 200-400 PPFD is good for early veg.
What are your thoughts?Week 1

Changing lights for auto flowerAt the beginning the light schedule was 18/6 after 2 weeks I changed it to 24hrs because the light was too weak (10w) I now got different stronger lights (600w)(finally arrived) With the stronger lights can I change it back to 18/6 ? It's autoflower.🤔🤔Week 3
