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

(NOTE: This post is the beginning of a series following our 100 Watt CFL demonstration grow from start to finish – seed to harvest. Bookmark or subscribe, and check back for weekly updates. 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.

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!

Using Your Own Marijuana Seeds From A Previous Grow

Critical+ crossed with Afghan Kush - what will the offspring look like?

Critical+ crossed with Afghan Kush – what will the offspring look like?

We get a lot of questions about cross-breeding your own marijuana strains and saving seeds. Here are a few thoughts on what you can do, and what you can expect.

First of all, saving your own seeds is entirely possible, and really rather easy to do. If you have ordered a non-feminized cannabis strain (maybe this is a reason to finally do so?) all you’ll need to do is keep a strong male plant after you separate males from females (see our post on sexing plants here).

You’ll need to collect pollen from the male plant and selectively pollinate Read More…

100 Watt LED Grow Results – RQS “Power Flower” Grow and Smoke Report

Ready for harvest. Almost too pretty to cut!

Royal Queen Seeds “Power Flower” ready for harvest. Almost too pretty to cut.

Thanks to all our readers for the great stats on our blog over the last months! We have been hard at work on new projects, and have not posted in a while, here are some new pictures of recent “small home grow” results. Read More…

100w CFL Grow: Results

Dinafem Critical+ Harvest Day

Dinafem Critical+ Harvest Day

After a close peek at the trichomes with a 20x magnifier, I decided it was time to harvest these hundred-Watt beauties. Honestly, the DG x AK cross could have gone another week or 10 days, but I had the free time at that point. (Please note that this was about 10 days ago now, so I have dried harvest weights available below.

So now the payoff: What did we get for our gardening efforts under 100 Watts of CFL lighting? Read More…

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.

If you are looking to reproduce this kind of grow (or a larger home grow), then you should pick up our eBook along with the various grow materials you will need – in fact, the book will help you prepare your grow so that your plants will be healthy, happy, flowering plants in just two months, too!

Be back soon with more,

100 Watt CFL Grow / Update#5: How To Recognize Male And Female Marijuana Plants Early In Flowering

In The Jungle

I must first apologize for the long pause between posts. All the plants have recovered nicely from topping, and have now been under 12/12 for one week. (For those of you unfamiliar with the trade jargon, “12/12″ is short for “12 hours of darkness, 12 of light” – the requisite light conditions to bring maturing marijuana plants into the flowering phase.) It is now time to see if we can determine which plants are male, and which are female. Male plants will be removed and composted in this case, I have enough pollen to last for a long time, and want to focus attention on producing the best possible buds on this low-wattage grow.

If you have been following these posts, you know that two of the plants were our own hybrids; a male “Double Gum” plant crossed with an autoflowering female. The autoflowering trait is recessive, and it turned out that neither plant was autoflowering. They also both turned out to be male, as we will see in a moment. Read More…
