This is my first time ever growing cannabis. I have grown tomato, cucumber, peppers, celery, roses and cabbage in the past.
**PLEASE GIVE AS MUCH GUIDANCE AS POSSIBLE, ALL ARE WELCOME**
I will be growing the Dinafem OG Kush Autoflower strain. OG kush is my all time favorite strain.
I buy 3 Dinafem seeds at local grow shop. I start 2 seed with Root Riot cube in egg tray under light with 5ml water for 2 days, then nutrients begin.
I am using a 20L generic Deep Water Culture for both plants. Water is PH 7.2 from tap, I use GHE PH Down to get to 6-6.2
I build a 1L CO2 Reactor with water filtration chamber to increase yield. Will last 4 weeks, recipe below. Will change at week 4 and week 8.
The light is a new Mars Hydro TS 600 which will be on a 20/4 cycle during veg, have not decided about flower. Lights are off from 0400-0800.
Photos are captured daily at 1400.
This will be fun. I will be outlining the entire grow with daily updates when the day is complete.
Outline:
Day 1 = placed 2 seeds from Dinafem can in root riot added 5 ml nutrient solution per GHE recommendations.
a. Pointed end of seed pointing up, deep into root riot, under glass bowl (humidity dome) under 20/4 light at 30cm. (later discovered that this was too low!! 60cm for TS600!)
Day 2 = seeds germinated well in 24 hrs, 100% germination rate 2 for 2.
a. seeds in root riot in egg tray are under glass bowl (humidity dome) in tent
Day 3 = both ladies have sprouted, one seems to be a bit more vigorous.
a. introduced heavy nutrients at 318ppm to both ladies.
b. removed glass bowl (humidity dome)
c. activated 1L CO2 reactor, 800ml warm water, 400g white sugar, 1/4 teaspoon of Instant Yeast.
d. Temperature 25.1 degrees Humidity 50%
Day 4 = Cotyledon and first leaves visible.
a. 1st plant is doing well, showing a long root at base of root riot. 2nd plant no roots yet through root riot.
Day 5 = plants in root riot placed in DWC
a. Nutrients at 320ppm for top feeding until roots hit the water level DWC. Water level is 3cm from base of basket to prevent overwatering.
b. Top feeding 10ml of water a day to the seedlings, want them to find the water supply soon. Using 15L/20L for water supply.
c. Water supply in DWC is 420ppm with Fulvic (Diamond Nectar) and Silicate (Mineral Magic) added per GHE first roots recommendations.
d. growth is very noticeable from Day 4 to 5.
e. Using the 420ppm solution from the DWC to hand water 20ml every 8 hours during transplant.
f. Temperature 23.4 degrees PM, Humidity 50%
Day 6 = roots starting to show through basket
a. bottom of basket is getting a good mist from the oxygenated DWC 420ppm nutrient water.
b. one plant is a bit more vigorous still.
c. Will not be top watering today, the DWC mist in the air gap inside the DWC is hydrating enough to push the roots into the nutrients.
d. Temperature 24.4 degrees, humidity 45%
Day 7 = Noticeable growth overnight
a. watered the rocks with plain 6.0 PH water to keep humidity steady around the ladies
b. Temperature is 25.5 degrees, humidity 45%
c. LED is now at 60cm from plants, seems to be a good height from the Mars Hydro TS 600 Quantum Board. (having the light too low during the first week did burn the leaves a little, had to trim in week 3)
Let the Vegetation phase begin!
Week 1 went really well, the two plants are doing great. Their roots are stretching out into the DWC nutrient mist.
Ive been providing the rocks with an injection of 60ml of 6.0 PH plain water just to keep humidity around the ladies nice.
DWC has 15L of 420ppm nutrient water from GHE Expert chart.
Day 8 = Roots have made their way into the DWC nutrient pool. The 5L misty gap inside the DWC has worked well.
a. growth is nice overnight. I expect to see exponential growth over the next few weeks.
b. I will not open the DWC again to prevent contamination, will feed through port in lid onward.
b. CO2 reactor is pumping strong. I will likely add another CO2 reactor at week 3.
c. once the roots hit the bottom of the DWC I will increase nutrients, for now 420ppm.
Day 9 - Root Growth extreme
a. leaves and roots growing strong, noticeable growth overnight.
b. will not be opening the DWC lid again, will feed through port on top.
c. added 4.5ml of H202 diluted in 240ml 6.0 PH water, top fed injection, to aid in preventing hydroponic mould.
Day 10 - Noticeable growth overnight
a. one plant seems to be exactly 2 days behind the other, maybe germination was longer for her?
Day 11 - Foliar growth overnight
a. today is reservoir water change out, new nutrients, 420 ppm, last dose of Pro Roots/GH Roots.
b. used 20ml of 3% hydrogen peroxide when sterilizing the bucket, added in 15L fresh (left out overnight to rid of chlorine) 5.8 PH water.
Day 12 - Foliar growth overnight
Day 13 - Foliar growth overnight
Day 14 - Foliar growth overnight
a. working the PH a little for the DWC, setting it from now on to 5.7-5.8 PH with mineral water. Tap water seems too hard, has naturally high ppm and PH. DWC seems to like a PH around 5.7.
b. added 1/2 teaspoon more Instant Yeast to CO2 rector, shook a little, fizzed up nicely, placed back in tent, next to DWC. 500ppm is based off of experiments I found online in the fish/aquarium world with same recipe am running. there may be really 900ppm because it has been stated that 400ppm is naturally in the air we breath.
***Week 2 is complete! Things are going well.
The two plants look and are growing a little different.. both from same sealed AutoDinafem can, maybe I got lucky and got an OG Kush leaning phenotype, and a Haze 2.0 leaning phenotype!!
Week 3 is off to a really great start! The growth last week is tremendous!
With GHE nutrients in a DWC it is literally set it and forget it. The earthy aroma inside the DWC smells like soil, I am guessing this is the Mineral Magic working its magic.
The plants like the lower PH, 5.7 alot! If you run DWC, take it from Dr. Kratky keep the PH under 6. I use an electronic tester as well as a chemical test kit from GHE
Outline:
Day 15 = growing like a real weed!! (Thanks @DinafemSeeds for the AWESOME genetics!)
a. I noticed that one of the ladies had some minor light burn (total spectrum LED was only 30cm away days 0-7) from the first week that she shot out of the root riot so fast! I clipped the damaged areas. I also subjected these ladies to nutrients day 1.
Day 16 = added an additional BIG 6L CO2 reactor to the tent, extreme veg growth continues, closing off passive air intakes except for 1 hour a day for CO2 saturation.
a. Recipe for CO2 reactor, 6L bottle with 2700 grams white sugar, 4L warm water, shake until dissolved, 2 teaspoons of activated instant yeast, and one ripe banana, poke many holes in bottle cap and place in tent. ill be adding another teaspoon of yeast, 200 grams of sugar and 300ml of water every week to this reactor. The 1L reactor is still pumping strong. when it is exhausted i will replace with additional 6L CO2 reactor. this recipe usually in most cases nets 700ppm of CO2 per week in a fish tank. ** Make sure to use a chopstick or something to stir the 6L reactor everyday to fizz up, mine smells like banana rum.
b. Observing one plant skipped its 2nd set of 3 finger leaves and went straight to growing 5.
c. Through the top feed port, the DWC smells like the purest soil I have ever smelled. Im using 4g/10L of GHE Silicate (Mineral Magic) along with GHE Pro Roots (black root sludge elixir from the gods). I think this is what is making the DWC smell so nice.
d. Added 1L of nutrient solution, minus the GHE PRO Roots, to the DWC, the ladies have already drank about 1.5L of water. Nutrients are sitting at 500ppm, and the solution in DWC is always 19-20 degrees.
Day 17 = explosive growth overnight - smells like kush in the tent.
a. the plants are developing their finger leaves at the nodes, the height of the plants is increasing tremendously.
b. the PH of my DWC is sitting at 5.9 this morning, I am planning on letting it sit there.
c. i give the ladies 1hr of fresh passive air intake, after that its CO2 saturation for 23 hrs. I added 2 tsp of activated yeast to 6L CO2 reactor. The bubbles were many!
d. the plants are showing no signs of nutrient dislike, so I upped the PPM to 580 with an extra 1 liter of 5.8 PH nutrient solution.
Day 18 - growing really well!
a. added second 6L CO2 reactor, same recipe as first. I removed the 1L germination reactor and added the contents into new 6L reactor and 3L warm water to total 4L in the tank.
b. performed ist LST to train these ladies away from each other.
@Saint, I studied your grow and want to say, wow! Your grow is incredible, it is what made me choose OG Kush in Dinafem Auto, instead of doing Dinafem White Widow photoperiod. Both my top two, tied for favorite strains to medicate with. When in Barcelona we always go to club that uses Dinafem, always top top shelf. Thank you!! ✋
