    When to flower is a big decision, as it affects your out come in several ways. Obviously, flowering after a longer vegetation period will provide a larger plant capable of a higher yield. But, if you wait too long and crowd your growspace, your yields could be substantially less. So, the idea is to balance the size of your plants with the size of your growsapce AND watts your providing.

    More watts penetrate deeper into the leaf canopy. Giving you the ability to grow larger plants. Anything under a thousand watts should be flowered no taller than a foot. Plants gown under multiple thousands can be grown much larger. Flowering them as tall as 2.5 feet tall if it suits your style and have the vertical space. But know this, a larger plant doesn’t always ensure a higher yield.

    My ideal size for time/yield ratio is to flower between 2-3 feet in height, depending on the strain. I like to use as much of the vertical space as possible, while still having room to have the lights at least 2 feet above the plants for ripening. A little more is even better…:-)

    The trick for lights under 1000 watts is to keep them close throughout the entire cycle. Keeping the light at around 12 inches above the plants will help your yield. You should hang a thermometer directly under the light, at the height of the tallest plant tip. Raising it as the plants grow. Keeping the temperature at plant tips between 80-82 degrees will encourage optimal growth. Use an oscillating fan blowing across the plant tips to cool the area.
    Nightime temperatures that dip to 10-15 degrees below daytime temperatures will encourage higher potency.

    WOW thanks Kyle I have to go move my light down then and re-position my thermometer….one other question I had was what RHI should I have while vegging? I seem to stay right around 20% only going up a little if I water…

    cannabis plants love humidity. most plants do. The only time high humidity is a bad thing is during the flowering cycle. When high humidity, especially drastic changes between day and night, will lead to budrot. For flowering humidity levels are best kept below 50% during the day and around 40% at night.
    For the vegetive stage high humidity will aid photosynthesis and speed up growth. Levels of 50-70% are helpful, but not necessary.
    If your humidity is truly that low you should foliar feed your plants twice a week during vegging and up until the 2nd week of flowering.
    Use a half strength grow solution. adding a little fulvic acid and Thrive alive is great too. You can even add all this to a microbe tea and spray it all at once.
    Give a fresh water foliar on occassion as well…:-)

    Great info. I like to switch to flower just under 2 ft. with the strain of og I run, it tends to stretch and finish right around 4 and half feet.

    I love OG too Chris. I estimate the average strain grows 50-100% during flowering…

    I am glad to see this site up an running. Congratulations Mr. Kushman 🙂

    I tend to flower at 18-24 inches tall. I am using 4k watts in a fairly small area, 10×8 to be exact. I will post pictures later this week. 100% fully veganic garden of Whitefire and Golden Pineapple. Will have some White Strawberry coming soon 😉 thanks for everything you do, you are in an inspiration haha

    I had someone else tell me that they like to let their main branches get 2ft tall before they flower too, I’m just hoping for bigger buds this time and I LOVE OG too! Works great on my pain : )

    I like to keep my bud canopy no larger than 2feet thick for optimal bud development…:-)

    i have two 4k rooms one is 10x10x8 and the other is 10x12x8 this is supplimented with 700 watts of t8 side lighting. i like to put 4 plants per 1k light with an 8-9 week veg period. ill harvest 5 1/2 ounces to 6 ounces a plant on average. i force the plants to stay under 24 inches in maximum heighth before flowering, and tend to go more by the diameter of the plants at 75% of my flowering rooms floor space covered.

    It’s nice to have plants as wide as they are tall during the vegetive stage…:-)
