Hi everybody,
Welcome to tronGrows #7
I really dropped the ball on tronGrows #6 having only posted 3 updates - compare this to tronGrows #5 where I posted dozens lol. Oh well. Onto #7, which I hope will be a little less lazy on my part...
This time around I'm going for ONE photoperiod plant, which I hope will be a monster. I'm ready for this bad boy to veg for 10 weeks if it has to! I'll be growing a single feminized Chemdawg strain from Humboldt Seed Organization. I was originally planning on growing a Bubba Kush also from HSO, but it damped off on me shortly after sprout. I've actually been having some bad luck with these HSO seeds from GTA Seedbank. I've had a very high germination success rate from various breeders via True North Seeds, but I've had several HSO's from GTA Seedbank damp off under similar conditions. Nothing against the breeder or seedbank - I'm a fan of both! Just luck of the draw I guess... Fortunately, this Chemdawg seems to be taking off, so I figure this is the time to try for a single plant grow.
To recap, tronGrows #6 featured three plants: a Cheese XXL Autoflower from Dinafem, a Master Kush photoperiod from Dutch Passion, and a Blueberry photoperiod from Canuk Seeds. Training wise, simply topping and LST. My yield was 8.5oz. On the other hand, tronGrows #6 featured a Super Lemon Haze and Sour Diesel both from Canuk Seeds, grown under a SCROG, and produced
nearly a pound in my 2x4! There's no denying a SCROG yield really speaks for itself with photos... so tronGrows #7 will feature the return of the SCROG! Overall, #6 was a bit more "loosey goosey" in terms of less training, less nutrients, less light, mishmash of photos/autos, and no automatic irrigation.
In terms of nutrients for #7, I'm stepping away from the 10-part General Hydroponics system and going with a bit of a custom formula using primarily Greenleaf Mega Crop 2-part, with some supplementals from NPK Industries (Yucca powder, amino acids and silica). I'm keeping a couple of GH bottles on hand: Cal Mag (my tap water is 0 ppm), Diamond Nectar (kelp + humic acids), and Rapid Start (for the molybdenum). As always, I'm keeping an Excel spreadsheet to keep track of my N-P-K-Ca-Mg-S ppm's to make sure everything is nicely balance. Careful with mixing line ups, kids! Kudos to Man O' Green for his insights...
Anyway, the Chemdawg is around 5 days from sprout. I'm using Pro-Mix HP (peat + perlite + dolomite lime + mycorrhizae). This is currently in a nursery bag under ~150ppfd. Initial medium soak was at 150 ppm (80ppm calmag + 70ppm Rapid Start + yucca); with one subsequent watering of calmag + rapid start + 25% Mega Crop + yucca at around 250ppm). pH at 6.4. Temps 26C and RH 72%.
Stay tuned!
