    This is my first grow, they sprouted on 12/7. I am worried that I am under watering them I usually water every 2 days. Lately the soil is getting very crusty and dry should i water them more?

    Medium- FF light warrior 160z cups
    Strain- 5 nirvana WW, 2 freebie autos
    Humidity- 40-50%
    Temp- 75-80 light on 70-75 light off
    light-4 26w 5000k CFLs on 20/4 light cycle

    They don’t look to shabby for a few weeks of age. Mine are that size by the first week, but at least they look decently healthy.

    You do want a good wet dry cycle, but it’s really BAD if you let your soil dry out to much before watering. If your soil is to dry most of your water will run right through instantly. Your soil wont hold as much moisture as it should.

    I grow with CFl’s a lot and have never bothered with 5000k in veg. I can say I tried them once but didn’t get the growth I wanted and was used to. I would use 1 x 2700k and 4 x 6500k in my veg box. I did however find a use for my 5000k bulbs. I use them in the last few weeks of flowering, and it seems to help a little with size. Not anything to write home about but I did go hmm on my last grow. So I will be using them again late in flowering next time.

    The only other thing I would recommend you do is kill the 24 / 0 light schedule with a massive axe. 24 / 0 is excellent for clones or the first few days of veg but thats it. If you must pump them with so much light at least go with 20 / 4 instead. It will promote better root growth. Thats probably the biggest reason why your two week plants are the size of my less then 1 weekers on an average grow.

    Anyways over all good job! Keep up the good work.

    Yeah just make sure you’re not over watering/ feeding the little girls. In the beginning they’ll take to minor changes and show it quite well how they’re feeling. You seem to have the light spectrum and watering down, (Just make sure to not over/ under water). Letting them just grow, and they’ll do just fine. Marijuana is a resilient plant and can thrive in many conditions that most think it would not.

    if you going to put them under intense light. than is best to water them before doing so if is time for them to be water. than after that start put them under the intense light, after that.

    this way you’ll be safe and not get the top dry out. seedling won’t be growing to much untill they take root. so that’s not untill like atleast 3-5 day after they rooted well and than shoot to cum up. by than you is still not too late to start putting intense light on them.

    using a 400 hid light for right now. it won’t hurt. and the leave might grow alittle better. but the root hasn’t take place yet. so there no reason to be hurry. is not going to start growing fast untill there is enough root.
    so it won’t hurt but is not necesarry to to use that much light at this put because it just wont be growing all that much without now root. if your plant is dying without light that yes give light to them. otherwise i say save some money eletrictricity and wait untill they are ready. it won’t hurt by giving plant alot of light right now, but it wil only help a little more than with cfl bulb. is really up to you what you want to do. if you want the plant to grow fast right away than do it, if you can wait i say wait. wither way will work but if you want to save money and not have to wait too long. you don’t have to put to much light on it at this point, not untill i say a good 13 more days.

    so is really bad if you want to grow but not want to use to much electricity at this point. cause 13 more days is still alot of days of light if you talking hids. cfl now is only about a function of the price but is no wrong or right anwser here. if you can afford it that i say try it once and try cfl next tiem and see what’s work best and choice if you want to save money for the extra growth during this time. than go with that later on your growing years.

    This is my first grow, they sprouted on 12/7. I am worried that I am under watering them I usually water every 2 days. Lately the soil is getting very…

    Cannabis Growth Timelapse: One Chapter at a Time (With Pictures)

    Last updated: May 4, 2020

    The growth of a cannabis plant can be divided into 5 main chapters: germination, seedling, vegetative, flowering, and finally, budding. Within these stages of growth, many changes occur to the plant that should be noted and carefully watched for by the grower. Here, we’re going to dive into these different stages, to give you an idea of how long things generally take and what to keep an eye out for during cannabis growth.

    Chapter 1: Germination

    This is where it all begins, the seed. During this formative stage of growth the cannabis seed, once planted or placed in a germination station, breaks apart and the spindly taproot emerges looking for nutrients.

    1-week-old plant

    The seed should be hard, dry and darker brown to grey before being used. Younger seeds won’t “pop” as readily. It can take up to a week to 10 days for the plant to finally emerge from its seed, but once it finally does it is ready to be transferred into a more permanent location.

    This is assuming the grower is using a germination technique that doesn’t involve direct planting, otherwise, they simply need to wait for the plant to sprout to begin the seedling phase.

    Chapter 2: Seedling

    As the taproot of the germinated plant begins to take hold, the first set of iconic fan leaves begin to develop. This signals the beginning of the plant’s seedling stage of growth and should be placed in a large growing area immediately if it hasn’t been done so already.

    2-week-old plant

    The first leaves should be developing at this point, which the plant uses to photosynthesize light into nutrients.

    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.

    3-week-old plant

    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. Once these seedlings fully develop these initial leaves and blades, they will be considered maturing and move onto the next stage of growth.

    Chapter 3: Vegetative

    After those initial leaves develop the plants begin to enter a stage of explosive growth. This is the vegetative stage. A healthy vegetative stage is the period of growth most associated with great yields, as the size of the plant can make a huge difference at the end of it all.

    This is also the stage with the greatest variability for the length of time it will take to get through, dependent on strains and growing conditions.

    It can last anywhere from 3-16 weeks, so knowledge of the particular strain being used is crucial here.

    4-6 week-old plant

    Somewhere in this time-frame is generally when the sex of a plant can be determined. The pre-flowers develop here, though they can be quite small, and once sex is determined it is time to separate the males from the females before any fertilization can take place.

    Sexing can technically wait until the flowering stage, but cautious growers should remove them now.

    7-12 week-old plant

    The length of the vegetative stage of growth is dependent on the genetics of the plant, as well as the period of time they are receiving light. Plants can technically remain in the vegetative state pretty much indefinitely, but eventually, it will hit its max growth or the amount of growth comfortable for the room and need to be switched over to flowering.

    There will be a ton of foliage at this point and the plants will want more water than seems possible. Any training should be done at this stage, as long as the plant is healthy and growing rapidly.

    Chapter 4: Flowering

    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.

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

    13-14 week-old plant

    This is the transition phase. It technically isn’t flowering at this point, but the plant will begin preparing for bud growth. The biggest growth occurs in this short period, the structure it develops within the vegetative stage is important now as the plant can almost double in height during this transition.

    Towards the end of these transition weeks, the first wispy, white hairs known as pistils will begin developing. These are what eventually will become the buds that you’re after.

    15-16 week-old plant

    Those pistils will begin developing larger and larger and become darker in color. This is also when the odor from the plant becomes very apparent, so a good filtration system is a must at this point for indoor grows.

    The growth of the plant will begin to slow down here as well, eventually stopping altogether as the plant’s energy will be focused entirely on the buds.

    Buds will not have grown too much at this point, so don’t worry if they are still fairly small.

    Chapter 5: Budding

    17 weeks and onward

    The final stage of flowering will have begun at this point for most plants, and the length of time can be variable. Buds will begin to grow very quickly now, seemingly overnight turning into dense flowers all over the plant.

    The rest of the growth is up to the plant, but when it seems to be getting close to harvest time flushing nutrients is important for a quality tasting harvest. Simply flush the plants with pH-balanced water and stop administering nutrients at this time to ensure a good harvest.

    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.

    Things like auto-flowering plants or quickly growing strains will heavily veer off this, but for the most part, following this guide will give a grower a good idea of what to expect each week of their growth.
