:point_right: My wife told me all my Diaries are probably dissmissed as TLDNR by most of the growers on here. Thats' OK. I do this diary for me and those who are weed nerds like me.

:point_right:This is the last seed of the 4 I received from Herbie's Head Shop of the Blow Mind Auto (Now called Sweet Amnesia Haze Auto) by Sweet Seeds. It has emerged a tap root and was placed in the media on 8-2. This was day 3 from placing in germination water. I'm excited about growing a Sweet Seeds strain.

:point_right: I will be doing Frequent Fertigation. Frequent Fertigation is giving the plant nutrients at optimum levels at a minimum of 2xs a day. The input nutrient solutions are mixed using the General Hydroponics Flora series full line of nutrients and mixed using the Drain to waste feed charts. Here is a link to that chart: https://gh.growgh.com/docs/Feedcharts/GH_FloraSeries-DTW_03216am.pdf My target pH is 5.8-6.0. My EC target is the upper end of the recommended range on the feed chart. I use RO water produced by an industrial grade machine I have access to but not at my residence. I mule the water in 2 6 gallon water carriers. This water is usually less than 5pH and averages 7microsiemens of EC. I have 2.5 gallon dispensers and mix each batch for 2 gallons mix level. The extra 1/2 gallon has proven to be the right amount to make upper level EC ranged solutions. Without that extra 1/2 gallon the solutions are usually over the limit. To get to the point where I knew 1/2 gallons extra would be enough, I mixed tons of batches with one or two gallons and then added water to weaken the solution EC to the desired range. The EC of the source water determines the final amount of water needed to weaken the mix solution to be in range.

Frequent fertigation is a labor intensive technique. Feeding at every irrigation event. This will not work in soil. Its a technique perfect for Coco Coir. I grew in collage in the 80s and experimented one plant with just clay pebbles. I liked the idea of a hybrid hydroponics/soil techniques. But that was my only serious grow till now because the risk of doing an illegal grow was too great for me. When legal growing a reality, I did lots of research on what methods I wanted to use. I dont like following the crowd, so when I cam across Dr Coco and the website Coco For Cannabis, I knew this was for me since I had done something similar 40 years ago.

Frequent Fertigation keeps coco coir at optimum levels of of pH and nutrient EC to maximize the plants ability to metabolize the nutrients. 2xs is the minimum number of events per day. If I had time for 3 or 4 I would try it, but without automation I simply dont have the opportunity to do more than 2x's a day. This has worked so far on all my plants. My results have been excellent and are far and away above the average plants that you find on this site. I will detail this method throughout this diary and will be happy to answer questions. I believe this technique is perfect for growing larger than the average plants and making lots of good big buds. I prefer autos for the longer light schedule and the low risk of after dark light exposure issues.

:point_right:The plant is in a 3 gallon pot filled with 2.5 gallons of Coco Coir and 1/2 gallon of expanded clay pebbles. This is 1/2 the amount of clay pebbles I have used in the past (normally 1/3 total volume). Not much data on expanded clay pebbles for coco beside just following the typical 1/3 total volume like the amount of perl-lite most use. I don't like per-lite for personal reasons...it is soft and can crush, its small, and the per-lite on the surface of plants I grow indoors or out, have algae grow on it, pebbles do not.

:point_right: Mars Hydro TS 1000 lights turned up full, so approximately 150watts. I may ad one more light to this plant later.

:point_right: To germinate I used a pH balance H2O solution with H2O2 added. I mixed 1 pint of water with 100ml of household (3%) H2O2. at 18hours I placed the seed in a black plastic container with a top, not air tight. Instead of paper towels I used a cellulose/cotton sheet cut to fit the container. I moistened the sheet with the H2O/H2O2 mixture. The area the seed germed in was about 77-78F (my entertainment center). The tap root emerged within 24hrs and I left in the container for 24hrs and placed in the media on day 3 just before doing this entry. I placed a plastic cup over the seed site.

:point_right:To prep the media I mixed 2.5 gallons of Coco with 1/2 gallons of expanded clay pebbles. I did this two weeks ago and have been rinsing the media daily with 1.5 liters of pH 6.4 pH .4ec water. I check the run-off to make sure the media is ballanced and buffered with no residual salt etc from the coco production.
