Luminous efficiency is great for cost comparisons on fixtures to be used in an office building but much like lumens themselves of no use to a grower.
BML provides a good breakdown here. Easy to understand in laymans terms, though I would encourage anyone interested to branch out to more...
DMF gives some good advice.

Happy Frog in SE Asia?.....
Well aged manure (fresh contains too much urine re:nitrogen, potentially burning plants) can be made into a nutrient slurry. Goat manure is considered cool but if saturated...

Waiting for the bulb to pop...
Gibberellic acid?
I've heard good things about soaking in kelp products but have not tried it.
I haven't got much and nothing it looks you're interested in but you're welcome to it. MOA Scotch Bonnet (not growing true it seems from other users) and a few non-iso strains the result of a...
There is a grower here named Vertically Challenged I believe that runs a vertical set up. And hordes of cannabis growers on other forums. May be helpful.
