Smokeythabear posted a topic in Autoflowering Cannabis World CupEnough talk of a journal, time to start one!! Here are the basic plans, some pictures, as well as my journal chronicling what has been happening over the past 9 days. Tonight they are being moved into their new bigger 23 L homes and I will have an updated post with pictures of the procedure soon. I wish everyone in the cup the best of luck and hope that I can provide both an informative and entertaining journal for all to read/view, and once again showcase the awesomeness of the Greenhouse Powderfeed! Peace GHSC Autoflower Cup Grow – 4 Strains – 6 plants Seeds: 2 x Super Critical Auto 2 x Sweet Mango Auto 1 x Northern Lights Auto 27/05/2013 - ** One NLA did not sprout so I am going to germinate 1 Big Bang Auto tonight. 1 x Big Bang Auto Growing media: Jiffy™ Peat starter pots – will transplant to 23 L pots once rooted in Jiffy’s 23 L pots - Pro Mix™ High Porosity/Grodan™ Growchunks/Hydrotron™ clay pellets @ approx. 40/40/20 mix Lighting: 18 hours on and 6 hours off entire grow Seedlings : 2 x Sunblaster™ T5 fluorescent - hung vertically on each side of the LED and angled towards the seedlings 1 x Sunshine Systems LED ** Lights will be kept a fair distance away as I am going for a mixed spectrum here not a ton of intensity Vegetation: 4 x 28W Sunshine Systems™ LED’s Flower: The 600W Hortilux Super HPS bulb w/cool tube reflector will be added once they are getting closer to flowering + 4 x LED’s Ventilation: Intake – (will be added once they are in the 23 L pots) via a 4 inch (10 cm), 176 cfm (300 M3/hr) Typhoon™ inline fan with a Mountain Air carbon filter attached on the intake end to provide some protection against fungi or bacteria etc. from entering the tent. This is new as so far I have relied only on passive intake, but I believe this could definitely improve yield. Extraction – via a 6 inch (15 cm), 280 cfm (475 M3/hr) CK™ inline fan with Mountain Air filter Water, Nutrients & Additives: Seedling transplant: All plants will receive Botanicare™ ZHO (Rhizosphere root inoculant w/trichoderma & mychorrizae) at transplant to 23 L pots Water & Nutrients: All plants will receive R/O (reverse osmosis) water + Botanicare™ Cal-Mag Plus and GHSC™ Mother’s Powderfeed once they are rooted and into 23 L pots until signs of flowering at which point they will be switched to the GHSC Hybrid Powderfeed. Unfortunately I don’t having any Indica powderfeed (other than 2 x 20 g sample packs that I will try out) which is recommended for autos but I was happy with the results once I started using the Hybrid feed last auto grow and hopefully using the Powderfeed from start to finish this time will only improve things. Additives will be used but not 100% sure which ones yet. And again, I will also use ZEO2™ CO2 producing pads for now, but am looking into other CO2 producing sources/methods for small spaces and this may change during the grow. 19/05/13 GERMINATION: Soaked seeds at 7:11 pm 19/05/13 in mineral water EC of 0.66, pH 6.8, temp @ 19 degrees to start, temperature should rise a few degrees. Glasses were placed in a box sealed from light and on top of the fridge where it will stay consistently warm. **EDIT** Having done more research, and having done this with the last Big Bang seed, I will in the future germinate with r/o water + tiny bit of Cal - Mag with EC no higher than 0.15, & pH @ 5.5. I was lazy and didn't pH and should have, and mineral water or not 0.66 is waay too high to germinate seeds considering they have all that they need in the seed to germinate. 20/05/2013 PLANTING: I opened the box 18 hrs later to find some seeds split their shell and others hadn’t. What is disturbing is that the water in each glass had a film on top of it L I used spring water that I’d opened a few months ago and sealed again, but with nothing persistent in the water to disinfect it (like chlorine in drinking water) something must have grown in it. I really should have known better with what I’ve learned in my water course in school and should have used fresh unopened spring water. I am hoping for the best but I fear the worst and I may need to purchase new seeds this coming weekend when I go to the Treating Yourself Expo in Toronto and start over if they don’t sprout into healthy little seedlings. Currently using one LED panel 18 inches directly above jiffys to germinate – with 2 x T5 Sunblaster fluorescents hanging vertically and angled towards the jiffy’s waiting to add mixed spectrum once they sprout and are a few days old. Once they are moved into their 23L homes I will have all 4 LED’s running until they are strong enough to add the 600W HPS Lights on 18 hrs: Room temp = 25 - 26°C rH = 55 % LED Light Height – 45 cm’s (18 inches) T5 = 23 cm’s (9 inches) from seedlings on the end Lights off 6 hrs: Room temp = 21°C rH = 65 % 21/05/13 No change 22/05/13 Today I added a heated seedling mat (* a new one, the old one would burn em up if not careful) to speed up the process a little I can see one SMA baby making her way up so far – I planted them a little deeper this time to help give them enough distance/friction to shed the seed and keeping them nice and moist while doing so. Having to spray and pry them off works but not always and having them worked off naturally is much preferred. @ 8:30 - one of each auto is showing signs of sprouting Lights on 18 hrs: Room temp = 23 °C Temp at base of jiffy pellets = 27 – 28 °C rH in room = 60 % average 23/05/13 @ 6 pm- approximately 77 hours after planting Sweet Mango Auto’s – both have split their shell and the bent stems are surfaced with cotyledons on their way up Super Critical Auto’s – Both have sprouted fully and look healthy Northern Lights Auto – one baby sprouted fully with healthy cotyledons, but 1st true leaves tips are looking white, I will keep an eye on her. The 2nd hasn’t shown signs of much yet so we will see. Watered - mixed new water: reverse osmosis w/small amount of Cal-Mag Plus EC = 0.4 pH = 5.5 Temp = 21 °C @ 8 pm - Now that almost all have sprouted and most have visible taproots I turned off heated mat, and turned on small ceramic oscillating heater to maintain proper temperature air temperature around 25 – 27. I want to get them into their new 23 L homes a lot quicker than the last autos and plan on transplanting them on Sunday or Monday most likely (in 3 – 4 days). Also started using the large humidifier to maintain target rH – around 65 – 70% for my set-up at this stage. Lights on 18 hrs: Room temp = 25 - 26 °C rH in room = 60 – 68 % 24/05/13 Status: Sweet Mango Auto’s – Both sprouted fully and with the exception of the very tips of the 1st true leaves looking a little white they look healthy. Super Critical Auto’s – Continue to grow 1st leaves and taller Northern Lights Auto – Still only the 1 baby sprouted outta 2, positive news is 1st true leaves looking more green and less brown and growing quickly. ** Going to buy a 5 pack of GHSC auto seeds this weekend, just not sure which ones yet, and may have 4 autoflower strains in the tent this time – maybe Big Bang? After time spent thinking about the cause of white tips on the first true leaves of some plants I considered that it is very unlikely that the autoflower seed-stock, especially of the new strains, would be very old and soaking them could create excess moisture causing the issue? Just a thought and maybe I’m wrong and it probably has to do with whatever was in the germination water – I’m sure these strong plants will fight anything nasty, crossing my fingers. LED Light Height = 40 cm’s (16 inches) Lights on 18 hrs: Room temp = 26 - 27 °C rH in room = 65-70 % Lights off 6 hrs: Room temp = 21°C rH = 65 – 70 % 27/05/13 – 4 days since sprouting Growth has been moving along nicely for the 5 babies. Second true leaves are already visible and the initial issues with white tips on some are already becoming a thing of the past. Taproots are visible as well as multiple feeder roots, especially on the Super Criticals. I’m going to wash up the 23 L pots tonight and transplant them in the next couple of days so as not to slow the rapid growth down. Tonight I’m also going to soak a Big Bang auto seed to take the place of the NLA seed that didn’t germinate, it’s my first try at growing 4 different strains together, and my first try at growing the Big Bang Auto last Auto grow I did 8 plants and 3 strains. Mixed new water: Reverse Osmosis (r/o) water +Cal Mag Plus to 0.4 EC + GHSC Mother’s Powderfeed to 0.6 EC total. pH = 5.6 Temp = 22 °C @ 10:45 pm – soaked a Big Bang Auto seed in r/o water + a few drops of Cal – Mag Plus = 0.20 EC & temperature @ 21 ° C. Placed in a light proof box in the grow room where it is about 25 – 26 °C LED Light Height = 35 cm’s (14 inches) T5 – 23 cm’s (9 inches) Lights on 18 hrs: Room temp = 25-27 °C rH in room = 65-75 % Lights off 6 hrs: Room temp = 22 °C rH = 70– 78 % 28/05/13 Planted a Big Bang auto seed after soaking it for 18 hrs in r/o water + Cal Mag Plus @ 0.30 EC & pH @ 6.0. Trying out a clear glass over top of the Jiffy to help improve rH and maintain a higher humidity around it until it sprouts. There are a number of gaps between the glass and the seedling tray which will allow some air exchange Noticed a few small orange/brown spots on the one Super C. auto and the Northern Lights auto. I don’t think it is anything serious and growth continues nicely. I am going to consider transplanting them tomorrow.
