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…
