78,600 lumens at canopy, ok for pre-flower and flowering?
DeadwebsiteBoringcommunityanswered grow question 5y ago
about 250-350 Umol or ppfd for Seedlings. 700-1000 Umol Veg and 1000-2000 Umol. Anything above 1000 umol Co2 is recommended.. The idea that having too much light causing damage is a more of myth or poor idea. The light intensity increases transportation to a point where the plant can not keep up with the amount of available light..

When will the plant be good?..Hi! I am a beginner grower. I converted a refrigerator for micro-growing. How long until my first plant is finished? It grew semi-open air. The box was ready a few weeks ago and I put it in. My lamp is viperspectra p600. I welcome any useful advice. Thanks.

Hight ProblemsI’ve got 3 plants in my tent, but they’re all different heights. To compensate, I’ve hung my light at an angle, so one end is closer to the smaller plants.
My question is: Does this help, or am I better off keeping the light level? Any tips for dealing with uneven plant heights?

I've found some lights I have left in my garage, and since I would like to upgrade my setup, I would like to know if these lights could function as grow lights.

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?

Best LEDs or small HID to replace 1000W dimmable HID for small spaceI'm using a 1000w HID setup I had from before, running at 50% in a cool tube. It's loud and not efficient. Maybe it's time I switch to LEDs or a 250 HID. I don't want to sacrifice bud quality but I'm low on funds. Any recommendations for a good light that will fill this space?
