One of the most common questions asked by novice growers is “What should my plants look like at x days/weeks old?”
Naturally, anyone putting their time and effort into a project wants to have a point of reference against which to judge their own progress (or that of their pants, in this case). The answer is:
Plants will vary in size and appearance depending on a variety of factors: Genetics, soil, lighting, nutrients, temperature, handling, and the elusive “green thumb” factor. As you can imagine, a plant growing outdoors under full sun in June (northern hemisphere) will be a lot bigger at 2 weeks old than a plant growing in a converted computer case running 50 watts of lighting!
In any case, cannabis plants do tend to develop certain physical characteristics at certain times in their life span (first true leaves after 3 – 4 days, alternating nodes after 30+ days of vegetative growth, calyxes and pistils after a week of flowering light schedule, for example). Barring any problems, after two weeks of vegetative growth, you can expect to see a plant with several sets of leaves, and are likely to be able to smell that characteristic “mary jane” smell on your fingers after gently rubbing the leaves.
Don’t be surprised if your plants leaves alternate between “reaching up” towards the light and “sloping downwards” towards the ground – this is normal. Leaf color will range from an intense, deep green to a light yellow-green or “lime” color. What isn’t normal is yellow leaves with stunted-looking new growth, patches of brown or browned edges, dark spots or a mottled look to the leaves, or leaves curling up into a sort of “taco” shape.
Here are some shots from our current 100 Watt CFL grow. A two-week old Dinafem Critical + plant. She’s (yes, “she” – this is the only feminized seed in this grow) looking quite healthy and of good size for the humble 100Watt grow. She’s ready for transplantation into the larger final grow pot.

Just two days after the previous post, the then-sprouting hybrid seeds are enjoying a “sun”bath in 6500k CFL lighting and are now showing their first true leaves. Three 25watt 6500k CFL bulbs are shown in the picture, and one more was moved out of the way for the picture – in total they will be under 100 watts for this grow.
This is a good chance to give you a few more seedling care tips that have occurred to me since the previous post on the topic. I like to start seedlings in soil, rather than in rockwool, special sponge pads, etc. I have had better luck in the past transplanting them into soil when they were started in soil.
In this case, I used some flower potting soil I had handy – which is usually a no-no! Read More…

It’s time to show you some step-by-step results from one of the techniques I recommend to home growers in our “How To Grow Cannabis At Home: A Guide To Indoor Medical Marijuana Growing” eBook – a 100 Watt grow using CFL bulbs on just two plants to keep the grow size manageable yet produce enough cannabis for personal use.
Growing with 100 Watts of CFL (Compact Florescent Lighting) may not provide you with heaps of buds at the end of the grow, but should be more than enough for your own use for quite some time. Beyond that Read More…
In a previous post, we mentioned helping a grower who had over-fertilized their Pineapple Express Autoflowering plant. By flushing the soil with plain, room-temperature water, we managed to get the “nutrient burn” under control, and the plant seemed on the way to recovery. Well, we got another call that the plant was not looking well, and this is what we found:

For first time growers, the most anticipated point in the process of growing your own marijuana is the begin of flowering. During your first grow, you will probably be checking every day to see if you’ve entered the home stretch and can anticipate your first harvest. This post is aimed at first-time growers who are eager to see their first results, and nervous as to whether everything is going the way it should!
The appearance of the fine, white pistils are the first recognizable sign that a marijuana plant has begun flowering – click on the image above to enlarge it and see the pistils in closer detail. The plant in the picture is a feminized, autoflowering “Pineapple Express” plant, and is approximately 5 days into flowering.
Spring is here in the northern hemisphere and, for home outdoor growers, it’s time to pop those seeds and get this year’s first grow started.
Novice growers should keep a few things in mind to ensure success during the delicate seedling stage. This short article will all but guarantee that your newly-sprouted seeds will soon be on their way to becoming healthy, happy adults. Here’s a list of 7 important tips to get your plants started right: Read More…
