    I am assuming that you've either read or watched a vid that says that adding fans will cause thick stems?

    There are three factors in my thinking that result in thick stems.
    1/ The genetics of the plant: If you are growing from seed then you will know toward the end of the flowering cycle whether or not the genetics of your plants are any good and worthwhile continuing by way of clones. If your plants come from spindly clones or from a thin stemmed mother, then there isnt much you can do to 'make' them grow bigger stems without dosing them with plant growth hormones like products with gibberellic acid during veg or products with cycocel in them during flowering.
    2/ Time: If the genetics are sorted, then its a matter of time before plants grow thick stems getting ready to support heavy buds.
    3/ Environment: The environment can help harden stems. Together with 1 & 2, environmental factors like wind, temps, lumens, all can have affect on how tough plants become, but environment alone will not grow thick stems without getting the genetics right and allowing plants to age.

    make sure light is no more than a couple of inchs away from the plant.
    also dont be scared of going in there and manhandling your plants bending manipulating and teasing the stems all strengthen and thicken it just make sure you dont do it hard enough to snap it and you'll find your plant will beef up quickly

    The stem will thicken if the plant senses it needs more stability, so a light regular breeze (enough to move the leaves around a bit) or a good shake a couple times a day will cause it to thicken in response.

    Additional calcium is the only method I know of when it comes to nutrients that may help.

    When talking stem thicknes one very important rule comes into play WHY should it thicken
    Unless you have enough fan power to keep your plant pretty much blowed side ways its only gonna help slightly

    So with that said we need to make it think it needs a sturdier stem
    There are two ways to do this the first is to top fim or prune at a realitvly young age

    If your already a month into it and plan to flower soon I would go with lsting or low stress training, this is the art of tying your plant over at about a 90 degree angle this will send hormones to lower nodes increasing the thicknes of the stem along with providin an equal foilage

    Hope this helps check out my stem from the grow in my signature

    Use Quantum Growth Plant nutrient distributed by Douglas Speed and associates out of Ponte Vedra bch. Fl. 100% organic and biodegradeable. It is a living microbe that can create the nutrients needed by plants ten times faster than the plant can itself it also provides any organisms in the soil with their nutrients so there not taking them from the plant. You also can cut back on other pesticides and fungicides using the product because it promotes healthier soil and plant and diesease and fungus rarly attack a healty plant. Try it on one plant you will end up using it on all. It's great with propergating and cloning. Indoorman and microbe user

    The stem represents the root mass. So if you want huge stems help the roots.

    Two things.... light and pruning.

    Light bulbs only make two things..... Light and heat. The more efficient they are the more light to heat ratio is made. Id ditch to florescents in favor of a MH for veg. Light intensity plays a role in how bushy plants are and spectrum is important as well. the more blue (6500K) to indigo spectrums (10,000k) will give squat leafy plants. The more bushy a plant the longer it can be grown in a small space and the thicker the stem will become. topping them will promote slowed vertical growth, multiple main colas, and let the shoots in the undergrowth catch up to the top. Topping always gets me THICK stalks. For yield you want your girlys bushy as poss so when you flower, their stretch is reduced (and split between the now multiple colas) and you can get the bulb(s) closer to the lowest of shoots.

    Hope this post is of value!

    -best wishes

    Is this really a great opportunity to spew your advertising all over a thread that is very sought after for questions about thickness of stems. We all know that nutrients place a crucial roll in the development of the root mass which in turn shows in the thickness of the main stalk. It also has alot to do with wind conditioning and cell development. I tend to bend a nub in the base of my main stems about 3 weeks into veg. Thicker stems more stable cola's. Simply advertising for this Quantum Nutrient by Gods speed w/e isn't answering any question and is fucken pissen me off. I have seen 30+ threads with the same copy and past advertising. Personally please use Fox Farm nuts or any other product found on any hydro store website before this junk spam....

    Thank you for the info grim no thread hijacking on my watch god damit!

    if you want thick stems the absolute fastest way no matter the strain is to low stress train them constantly. in a couple weeks the stem will doubled in size, in a month it will be 4-6x thicker.
