I am interested in watching you learn to scrog, as I will be next in a few months. Genius use of a shower rod!

Week 6 (from cotyledons) in the books. Flowers are developing. I will increase the Canna ferts to 900 ppm with pk 12/14 in week 7. I managed to break the blue dream top while supercropping it. Now, there are two tops growing. I have supercropped a lot of the taller plants to try and hold...

Week 5 (from cotyledons) completed. Much growth and flowers forming. The sativa's/dom's (Except green crack and the mutant Jack the ripper.) and the Bubba Kush are 3 feet tall. The rest are about 2' tall. I took down the Cookies and Kush plant, as it doesn't look like it will produce...

Week 4 is over. I increased the nutes, according to the Canna schedule, to about 650 ppm, including the tap water. I added a very weak root soak of Spinosad early in the week, and a day later, the Neamatodes arrived on ice. I don't think that the Spinosad killed the Neamatodes, as...

I am going to read about preventative pest management, as I know that I know very little about it. I did a soil drench at 2 teaspoons 0.5% spinosad in a gallon of water/ferts, and sprayed the top side of the leaves. I think the recommended amount is 4 Tbs/gallon, so starting light. I...

HLG-240H-1750 with 4 Cree CXB 3590's? Works great! Meter pictured here is a little low. The DVM verifies 1.75 amps. Thanks all!

My first time sexing a regular. I would venture that this Querkle (TGA) is female, based upon the appearance of white hairs around the 4th node. No sacs. Feedback welcome!

I do have some spinosad left over from drenching spring spinach roots about 4 years ago. I ordered some "beneficial nematodes" from Amazon (!!), and if they arrive in the next couple of days, I will add them to the food/coir web, and let them have at the larvre. If that fails, will try the...

Week 3 (since cotyledon rose) is in the books. A large amount of growth and lush leaf on the Kushes, and 6"-8" or so on the Girl Scout Cookies, Green Crack, and Blue Mystic. It is fun observing this grow, not knowing exactly what to expect, and trying to keep it generic as possible. The lure...

End of week 2. Except for the originally 2-stemmed Jack the Ripper, everybody is looking good. They have nice growth, especially the two cookies strains. I added a "pinch" of Yucca to both the ferts, and the 10ml/liter Rhizotonic that I foliar spray with after right lights on. It is supposed...

1.75A = 169 Lumans/Watt (bin DB @50C) 1.4A = 178 Lumans/Watt (bin DB @50C) (2.3-ish umoles/joule ??:) I am guessing that they are even more efficient at 1A, and even more so at 0.7A, and probably even more so at 0.001A Right now, I want 30K lux (I don't have a umol meter) for veg, and...

I was pretty sure that forward voltage went down at higher temps. It does, by about 0.4v each, going from 25C to 50C. I am guessing it will work, as long as the initial room temperature is closer to cool/warm. than to freezing. The other thread mentioned earlier indicates that the COBs will...

Hi, I was looking at the Mean Well HLG-240H-C1750 on RapidLED for driving 4 Cree 3590's at 1750ma. The Rapid web site suggests using this driver with 2-3 36v COBs. I used a Cree online tool, and determined that at 1750 ma, the COBS are likely to have a voltage drop for 35.5 Volts. So 4...

12/12. 1 cola. No mainlining this run. I used 2 regulars, because I have never used them before, and wanted practice determining sex, before I do a larger run with them. This is more of an experimental fun learning grow for me. ;) I also have never grown anything that was more than 20%...

The 2-headed seedling (TGA's Jack the Ripper), is looking more normal with a single stem. Hopefully, it won't remain the 'runt' of the early veg cycle. before/after:

I have also done a milk crate lined with garden weed screen outdoors, but not with cannabis. That holds about 7 gallons of soil. The air pots are over 10 years old now, and the only ones showing wear, are the ones left in the sun for a couple of summers. I really like how the bottom is open...

The black air pots are awesome. I have small pint-ish sized ones for starting plants. I have been able to start and transplant other non-transplantable plants with them before. I also have the 2 gallons, (8"), which I am using this time, and the 4-ish gallon (12") airpots which I used last...

The first week since coming above the soil (coco) has been completed! I decided to transplant early, (usually do this early in the 3rd week with air pots), as the seedlings were a bit stretched. The first day or two, I was lighting with 15k and 20k lux at the leaves, as measured by the...

Thanks Mister Magoo! It was a _lot_ of fun to do!

Some people have managed to go perpetual with 12/12, but I will be trying something else come January ;)
