Lighting How much LED watts for my tent

[Rwg111]

I have two Meizhi 600W over 3' x 6' of available canopy square footage. Do you think I'll do well with 5 plants in 5 gallon smart pots? Can you recommend a height for Veg & Bloom? Thanks!

I think you'll do fine with that. I hung mine at 30 inches from the start and never moved them unless a top breached the 10 inch mark.but I did heavy training for an even canopy

First off, your using Lumens...which is likely the worst way possible to measure lighting when it comes to photosynthesis. And DLI is what I and Mizzo was referring too. And just for clarification, you can go over 1000-1200 PPFD your not going to hurt your plants. They just wont be able to use the light so your wasting energy/$$.

Running about 565 PPFD on 3 Bears and a few others with co2 900 ..... I get canoeing on the leaves if I try and push too much light, especially on 3 Bears OG, she does not like much over 565.

Amount of light a plant can handle and use is dependent on numerous factors including but not limited to:

Temps, humidity, co2 levels and other factors, as @ColoradoDreaming420 @Mizzo81 @Mañ'O'Green @KonopCh

But one overlooked is Strain ..... Don’t quote me but generally a sativa can handle more light than a indica and within each strain, especially with all these crosses, plants have their own tolerance / sweet spots .....

Here’s a podcast .... they talk about PPFD Levels and sweet spots . Made me smarter ..... check it out:

I have the same size tent and have 2 600w led lights and 1 autocob and all I've noticed the past month is an explosion of growth and massive buds.
