cannabis seed sprouting time lapse

Flowering is triggered by the light cycle shifting to 12 hours on and off, so the timing of it will vary from growing to grow but this generally begins around week 13 of a grow.

The weeks involved for each plant are variable for a lot of conditions, but this is a good general gist of what each week and group of weeks involve for standard cannabis grow.

This is the final stage of cannabis growth. All the previous work keeping the plant healthy and structurally sound pays dividends here as the plants begin to produce their buds. All males need to be removed at this point, otherwise, fertilization will occur and the females will lose a fair amount of yield and quality.

It will grow a bit taller and begin to straighten up during this week. The very first new growths will appear as well, which will be another leaf along with the development of additional blades on the current leaves. Initially, they will be quite small.

A healthy plant will start turning a more vibrant green color and those blades will finally start becoming sizable, it will start looking more and more like a marijuana plant at this point.

Seedling & Vegetative Stage

I sprayed Dr. Doom on this young plant to try to combat spider mites. Plant is under a 42w CFL. The main apex was also burned which stopped growing but eventually a new one formed off center. New leaves sprouted just above the cotyledons as well. Don’t spray pyrethrum-based products with any grow lights still on! Pyrethrum is an ingredient in certain insecticides. In this case it came from Dr. Doom. Pyrethrum is very photoreactive so because it was sprayed with the lights on it created a bad situation on the plant as you can see. It almost appears to burn it. The growth was very gnarly for awhile afterwards!
