100 Watt CFL Grow / Update#8: Catching up – Marijuana Pants Near The End Of Flowering

One Month into Flowering - Dinafem Critical +

One Month into Flowering – Dinafem Critical +

Thanks for tuning in again, and my apologies about not sticking to weekly updates as I had hoped to do.

The plants are actually now harvested, and I am surprised at the results. You’ll soon see that 100 Watts (or a hair more) of CFL lighting can make you a rather happy home grower. But I digress… We first need to catch up with some pictures from last week showing our two plants in the final weeks of flowering. They fattened up nicely, although the Double Gum/Afghan Kush cross kept itself well hidden in a wreath of dark green leaves.

The above photo is from a little over 2 weeks ago – showing the Dinafem Critical + plant at four weeks of flowering. Below are some more pictures from last week (Nov 9th) at about 6 weeks into flowering. Checking the trichomes showed a lot of milky heads and even a few browned (oxidized) trichomes, so the time was coming for harvest this week.

Here are some pictures of the Critical + plant last week:

Critical+ 6 Weeks Flowering Critical+ All Buds 6 Weeks

Not bad for an easy home grow/hardware tore/CFL grow! Be sure to pick up our ebook for all the right tips on getting these kind of results at home!

The DG x AK cross could have gone another week or more – the buds just weren’t quite as developed as the Crit+, and she looked like she wanted to make yet another stretch up for the sky! That’s how it is with some Sativa hybrids (the Double Gum genes) and crossbred plants are always unpredictable:

Up, up and away... the DG x AK cross-bred plant wants to keep going.

Up, up and away… the DG x AK cross-bred plant wants to keep going.

Alright – next week I will post the harvest photos. Be sure to come back and see what this project was able to produce! The Dinafen Critical + pictures above should give you a hint…

What Do Marijuana Plants Look Like After 3 Weeks Of Flowering?

Here are some pictures from an LED Grow that we have running parallel to the 100 Watt CFL Grow that I have featured in recent posts. I thought it might interest readers to have a comparative peek at how buds look after 3 weeks of flowering under LED lamps compared to how they look after 3 Weeks under 100 (or so) watts of CFL.

I haven’t attempted to color-correct the raw images here – the LED lamps tend to create a psychedelic-looking deep red/purple light, whereas the CFL 2700k bulbs are more typical of what you’d expect in a room (soft white).

First of all, for those of you following our 100 Watt CF grow, here are pictures of the Dinafem Critical + (first) and Afghan Kush x Double Gum cross (second).

The AKxDG has recently made a more Sativa-like turn (despite the early indications of Indica-dominance due to the wide leaves), growing taller and leafier at the top, and with buds along the stem, instead of a dense cluster at the top. The Critical + plant is doing very well under the CFL lights, and promises to be an excellent producer under low-wattage conditions.

The following are shots of an LED grow (multiple 125 Watt lamps are in use) where we currently have an African Sativa land-race strain that has been flowering for just under 3 Weeks (started them just after the 100 Watt CFL grow plants):

Although LED lighting may be too expensive for the budget home grower, I feel that the added expense may be worth the upgrade over the long term. The buds under the LED lamps show healthier, more robust growth in a slightly shorter period of time – compare the fullness of the buds, and density of pistil growth to the above CFL grow pictures.

On the other hand, the startup costs for the CFL grow are next to nothing compared to an LED lighting rig! Stay tuned and we’ll see what the CFL plants look like next week as we start the 2 week (or so) countdown to harvest time.

100 Watt CFL Grow / Update#6: What Should A Marijuana Plant Look Like After Two Weeks Of Flowering?

Dinafem Critical+ 2 Weeks Flowering

After two weeks of flowering, the two female plants in this grow are looking great – lots of white pistils, and calyxes beginning to thicken at the bases. This is really a low-maintenance part of the grow. The light schedule is 12 on/12 off, and the plants are getting alternating waterings of plain water and our “Sweet Jane Molasses Drink” (see the next upcoming post for the recipe and why molasses is a great fertilizer/soil booster).

The lights are switched to 2700k bulbs, and I must note that the total wattage is in fact up closer to 150 Watts at this point. The most efficient CFL 2700 Watt bulbs I found for this “homestyle” grow are 33 Watts each. I replaced four 25 Watt 6500k bulbs with 33 Watt 2700k bulbs, for a total of 132 Watts of lighting. This is “cheating” in a way, since I wanted to stick to around 100 Watts, but I felt it was more fitting to keep two bulbs on each plant instead of reducing the lighting during flowering, which would be a bad idea. If you are running a similar low-wattage grow, I suggest you err on the higher side for lighting during flowering, as this is critical for bud formation.

I know some comments will come in to the effect of “Why don’t you put them under 250 Watts HPS for flowering!? You won’t get fat buds under CFL bulbs!!” Well, why not put them under 600 Watts then? Or just outside in the full sun? Well, that’s not the point of this particular grow journal!

I know there are a lot of growers out there who would like to use hardware store supplies, and keep their power consumption down for various reasons. This journal is here to show what someone growing under these conditions can expect if they otherwise follow proper growing techniques. The above photo is the Dinafem Critical+ plant, and the following photo the Afghan Kush / Double Gum crossbreed. Both plants are now 8 weeks old (give or take a day or two) and have been flowering for just over two weeks.

Can I grow marijuana from bag seed / street seeds? 5 Reasons to buy seeds.

For the budget grower, or in a place where you can’t legally order seeds, you’re probably wondering if you can grow marijuana from the seeds found “in the bag”. It is, hands down, the most common question I get from those considering about growing their own. The answer is yes! But…

There are a few reasons that someone looking to grow their own would want to buy seeds from a seed bank/dispensary/head shop/etc. Let me start with the positive and tell you why this will work, and then tell you the downsides, and you can weigh it out for yourself. Read More…

How To Top / Trim A Marijuana Plant To Keep It “Short”

Looking for the terminal bud on a sativa-dominant marijuana plant.

Looking for the terminal bud on a sativa-dominant marijuana plant.

One of the problems faced by home growers is the daunting prognostication of the height your plants may reach! If you have chosen a Sativa strain (or even a sativa mix), you may be looking at the potential for the plant to reach 6 to 8 feet in height (growing conditions permitting) by the end of your grow. Yipes! That’s just a teeny bit bigger than my grow cabinet…

Autoflowering strain growers take note: Don’t top/trim your plants – they won’t like it, and don’t need it. They’re on a tight growth schedule, and most varieties won’t reach more than 3-4 feet tall.

The particularly tricky part is that Read More…

100 Watt CFL Grow / Update#2: What Should A Marijuana Plant Look Like At 2 Weeks Old?

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.

In The Nursery / Under 75 Watts CFL 6500k

In The Nursery / Under 6500k CFL Bulbs

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…

100 Watt CFL Grow / Dinafem Critical+ And Our Own Hybrids!

This post is stickied to the home page for the time being, and each update will appear right below this introduction. Thanks for joining us!)

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.

Cadets In Training For A 100W CFL Grow.

Cadets In Training For A 100W CFL Grow.

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, the light output per watt of power consumed is excellent for 25 Watt (or thereabout) CFL bulbs. This translates to more light output – and therefore more marijuana output – per watt of energy put in. An energy efficient grow is not only environmentally friendly, it also keeps both the power bill down. Should you be concerned about drawing too much electric and therefore unwelcome attention to your grow, then this is the method for you.

I’ll be posting pictures of the grow from seedlings to dried & cured buds, so stay tuned to this post.

Want to know what this grow will cost in electricity? With 100 watts of lighting on 18 hours/day for 30 days (vegetative phase), you have 30 days x 1.8kWH =  54kWH. Flowering is only 12 hours a day, so 1.2kWH x (let’s say) 50 days for flowering = 60kWH. Even rounding up for fans and ventilation,  total power consumption for lighting is about 120kWH.

If you pay 25 cents per kilowatt hour, the electricity for this grow will cost you roughly $30 in electricity! That is not bad at all. The big question then becomes – How much dried and cured bud will I get out of a 100W grow? Follow this journal, and you’ll see first hand!

Pineapple Express Grow Problem – What Is Wrong and How To Help.

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:

How To Tell If Marijuana Is Flowering

Flowering Begins

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.
