I got a pair of these Method Seven Agent 939 FX Full Spectrum LED Grow Glasses at the grow store for $85 yesterday. They do seem to work better than a pair of Oakley's, feels like my eyes can relax more. I think they give everything a slightly green tint if anything. Also I think the frames on...

I ordered a $350 Zkittlez clone from HM Clones on May 22. It was supposed to ship in 14 days but took 27 days to arrive. I emailed them after 3 weeks and they replied that it would ship out the next week, which it did. HM Clones is in Oregon so that's where I expected the clone to ship from...

I sent a clone I hunted to a trusted friend last year as a gift. He recently contacted me saying that his old boss who owns a nursery wants to "propagate" it. He sold a few trays of clones last year and wants to keep it in his rotation. They kindly asked if I was tying to keep the strain under...

I got the one kilo bag of this Jack's RO formula. It already has cal mag, and is also supposed to prevent "pH crash." It says to mix 3 grams in 1 gallon of water to achieve 0.92 EC. I did this and it came out to 0.89 EC, so that's good. I put another 2.5 grams in and got 1.5 EC. The problem is...

Simply pH your flush water to 6.8 and warm it to 75-78 degrees. Phosphorus is much more water soluble at this pH than it is at the 5.8-6.0 that Maximum Yield recommends for flushing. Just look at any nutrient soil solubility chart. At a pH of 5.8-6.0, phosphorus is in the red zone, meaning it's...

I was looking at a bunch of different 2-part AB bloom nutrients today. I compiled a list. There's a few powdered nutrients on there too. A few common ones aren't on this list. Either the numbers were hard to find, or I've used it before, and am looking for something new. I've been using the...

I thought I'd try growing in 6" rockwool blocks with FloraFlex caps on my drip tables. I've always used soil, soilless peat mix, coco or hydroton before. I followed the instructions and soaked a couple blocks in pH 5.5 water for 30 minutes. Afterwards, the water was really soapy looking, sudsy...

I have a bunch of 5.88" heatsinks, 24" long, with (4) CXA-3070 running at 1400mA, fan cooled, on the old method of one driver per COB (driver board). I want to convert them to CXB-3590's at 1050mA with Mean Well HLG-120H-1050C drivers, passively cooled. The LED DIY Calculator says the heatsink...

I've misplaced the 12V DC adaptor that connects the Sentinel CPPM-4 to a temp controller (EVC-2). Can somebody who owns a CPPM-4 please look at their 12V adaptor and tell me what the milliamp rating is?

I started some seeds from my breeding project months ago. A few weeks after I put them in the flower room, I noticed they had brought thrips with them. The thrips came in through a window that I had been opening at night during the summer, adjacent to the veg room. I should have sprayed them and...

I have a chemist who is interested in helping me develop some nutes. I'm thinking of a 2-part Coco AB. Ideas are: 1) Most of the Nitrogen (N) in one bottle (A or B). This way it can be selectively cut during flowering, as experienced growers do with GH Flora 3-part, etc... 2) Potassium (K)...

The strain is called Conquest, from Illuminati Seeds. It's a back cross of OG Haze #4 (Amnesia Haze x Pestilence) x Pestilence. I grew another Illuminati strain before and got some killer phenos, still kicking myself for not cloning them. These are feminized seeds. Actually five of the plants in...

Years ago I read a paper about the ancient Chinese, Indian and Tibetans' use of medical cannabis. Does anyone remember that Rosetta mail order place in Berkeley? Anyway, one of the things I recall from that paper, these ancestors believed that long term, heavy cannabis use could lead to eventual...
