Hi folks,
Here the story....
I transplanted 1 week ago rooted cuttings (Critical) into 1 gallon smart pots. The coco brand i used is from UGRO, coco brick,
water capacity is 910% which is in my opinion quite a lot? Furthermore the package states EC<0.7.
I prepared my 4 year old stored coco brick 3 days before I tranplanted the cuttings. I used boiled water for a better penetration and for diying bad bacterias.
After cooling down I added also 10% Perlite and Mykos (1 Tablespoon for 1 gallon / 3 Liter).
I puted the fabric pots with no plants under my new warderobe (2 foot x 2 foot x 6 foot / 60 x 60cm x 200 cm )
and i did some heat test run tests with different effective airflows to check the behaviour of my new grow chamber.
3 days later my rooted cuttings arrived. I transplanted them into the fabric pots and gave them about a half liter with 1.0 EC, and i checked the drain. EC was 1.8. So i flushed immediatly with about 1.5 liter per pot with adjusted PH water of 6.0 with EC 0.3. Drain checked again with EC 0.9. Ok lets go under HPS. The rooted cuttings receive since day 1 about 30'000 Lumen.
I misted them with Rhizotonic.
They cuttings look fine next day but coco was still really soaked. Next day i misted them again. Till now here was no new growth of the cuttings visible.
The second day, because i was also reading a lot about growing again, I relised that the brand of my coco coir has beneficial Trichoderma in it and i realised they sure died with my hot water treatment.
I have seen pictures of mold with coco on the canna homepage if the coco receives a 30min steam treatment (quite similar too hot boiled water). So i added adjusted PH solved trichoderma solution with some Rhizotonic, about a 2 dl for each plant.
I misted the plants again with a Rhizotonic solution under the HPS light but the circulation fan was sure not running.
The next day suddenly all 6 plants looks not very well. The old lower leafs almost drying out (this leaf was already shortened as a fresh cut), the middle leafs are showing some brown points
and the whole plant looks slighly pale green. This change was in 1 day, so i guess i burned the plant during misting under HPS? My reference plant under LED light looks great.
What i have inspected:
- Better rinse the coco brick before transplant in this coco and check EC, i guess the filled coco bags are better rinsed, but i am scared from fungus gnats contamination, which i had in my old times...
- Soaked coco in bigger containers is not the best for fresh rooted cuttings, better let is slighly dry for 24h in the growroom for faster rootgrowth
- Don't mist the plant when the circulation fan is off under strong HPS light? I am sure with fan and T5 lamps no issue
My light is so strong with 30k Lumen, so i feed since day 4 with EC 1.3. Ok?
Now we are in day 7 of veg, the cutting starts to grow since two days and first roots on outer fabric pots are visible. New plant grow looks healthy but still little pale.
The clone is now about 6" / 15 cm. They started with a size of 4" / 10 cm. The Critical strain will gain about 200% stretch.
I intend today or tomorrow switch to 12/12, because of hight limitations. 60 cm plant / 2foot is about right.
How shall i proceed with my plants?
I guess still handwater at least the next seven days till roots have fully developed in the 1 gallon / 3 liter pot and then switch to automatic watering 3x/day.
I guess they can drink more? Or still some lockouts from the hot coco possible? Do i have to flush again?
I expect about 1 oz or 30 grams per plant.
Any advice is welcome
Thanks Coconutfarmer
