Grow- 1st Coco Grow, LSD and AK 39
I am growing 3 plants in coco, following Dr. Coco's nute chart. I was going to do 4 but my 4th plant was a bit of mutant and after talking with Dr. Coco I decided to cull it. It took a lot longer then I expected to set this all up, so happy to have the setup done (mostly).
Seeds / Strains
I am using LSD and AK 39 seeds from QSC, links below.
Tent: Secret Jardin L160
Light: 630 W CMH in air cooled Reflector
Fan : 6" Fusion Breath In-Line Fan, 480 CFM - The fan is running on a temperature switch. It turns on at 75*F, turns off at 72*F
I am using an auto watering system that drains into a drip tray and runs into a tote. Its pretty much the system that Dr Coco outlines in his DIY article.
I still need to buy a fan for inside the tent and a humidifier, maybe an intake fan later on.
I transplanted my 3 good plants into 5 gallon fabric pots, one of the AK-39 seeds was a bit of a mutant so it got culled. After transplanting I put them in my tent, set my CMH light to about 18" above the top of the plants and gave them the first feeding out of my new auto watering system.
Day 16 Update
On my first reservoir mix I added too much Yucca, after talking to Dr. Coco, I watered it down by about half, with a fertigation mix without any Yucca. When I started to measure my runoff EC it was far too high. started at about +500 from inflow. For the next two days I hand watered with a 50% watered down fert mix as suggest in the "how to manage run off EC guide". After 2 days my run off EC was back to normal. I have just mixed a new batch of fert in my reservoir this time with the correct amount of Yucca....
So I am now on week 3 of veg. following the Coco for Cannabis Nute Chart. My inflow is now at 1380 EC and after the first feeding with my fresh mix, my runoff for all three plants is 1100-1250 EC.
I have also made some additions to my tent. I got a new fan, its great it just clips onto the tent pole. I added the PVC tent support from the DIY section, my tent walls don't get pulled in nearly as much now. I also got a Humidifier and a Humidity Controller. My RH was getting too low with the light on and exhaust running. Now I just have to figure out how to lower the RH during the night cycle, its been creeping up to about 80% over the 6 hours the lights are off. I am thinking of adding a second exhaust with a 6" booster fan. My current exhaust fan is on a temperature switch. Not sure how to get it to trigger with high humidity at the same time (I need a way to trigger this fan based on 2 parameters temp and RH).
Day 19 Update
I topped my one AK-39 plant on day 18 and I topped my 2 LSD plants today, the LSD plants don't seem to be growing as fast as the AK-39 plant.
To solve my humidity problem I added a booster fan connected to my humidity controller. I also re arranged my ducting a bit and added insulation around the ducting to dampen any noise. My main inline fan is still connect to a temperature switch which comes on at 82 F turns off at 77 F.
Day 62 Update
I have been busy over the last month and I really need to update this Journal, its going to be a bit of a long post.
Since my last post I have added a dehumidifier, 30 gallon reservoir, Hydro Halos and 3 new fans one of which is already broken. I also re-worked my drainage system, I added a condensate pump but I will save those pics for the end of the update.
I added the hydro halos, only got one the correct size. Had to order the proper ones in and wait.
On day 35 I noticed a calcium deficiency, after getting some advise from Dr. Coco I upped my PH (stopped chasing 5.8) and also applied a cal mag foliage spray for the next 2 days twice a day.
I started the flip to flower, reducing the light 2 hours a day.
Day 2 of Flower (day 41)
Day 3 of Flower
I took some trimmings for clones
Day 12 of Flower
Day 15 of Flower (day 12 for the clones - last day in the cloner)
Day 16 of Flower
Day 18 of Flower
Day 19 of Flower
Day 20 of Flower
Day 25 of Flower
The few tops I can reach I did supercrop during the stretch, I have tied them off to the PVC tent support to keep them out of the light. I also Lollipoped them at the end of the stretch, I feel like I might have taken too much off.
woh gohh it
day 27 is Awesome.
