This is my second grow, but a first one in coco!
Setup:
Tent: Secret Jardin DS II 150
Ballast: ETI Ballast Duo 1000W
Light: Philips HPS 1000W SON-T PIA PLUS
Cool-tube: Ventilution Cool-Tube, 150mm, sitting on easy-rolls
Outtake air: Vents VK 150mm, 495m3/h
Intake air: passive
Running air: Hurricane Box Ventilator, 30cm (12")
Filter: Max Carbon Filter, 700m3
Hydro system: Modified Wilma 10 (11x6.5L pots & 80L waste reservoir + 80L nutirent reservoir)
Stream 700 Water Pump (730l/h)
EHEIM 200 Air Pump (connected to 2 diffusers)
Water control: Multi Meter (Digital PH + TDS (PPM/EC) + Temperature), all in one.
Air control: Digital Indoor Thermometer + Hygrometer
Growing medium: Coco (Biobizz Coco-Mix) + 25% Perlite
I chose coco because of the good things i read around here about it. It also seems easy to maintain.
Strains: 4x Delicious Seeds Critical Jack Herrer
5x Barney's Farm Blue Cheese
1x Samsara seeds Punky Lion
1x World of Seeds Afghan Kush X Yumbolt
For the seedlings i have:
Rootit pellets
+airdome
Nutes: Main: CANNA line (Aqua Vega + Aqua Flores) (I have a stock of these nutes and i won't pay extra for the ones made for coco)
Extras: House & Gardern's Roots Excelurator
House & Garden's Drip Clean
Growth Technology's Nitrozyme
Aptus Holland CaMg Boost
Advanced Nutrient's Big Bud
Advanced Nutrient's Overdrive
My tap water: 8.50 PH
170 PPM
I use phosphoric acid for lowering the PH but i was thinking getting some nitric acid or use a lemon, because the coco already has enough phosphorus and it does not go well with adding Ca/Mg Boost...
Nute sollution: 5.80 PH
0.45 EC for now.
Temperature & Humidity
28 degrees celsius
20-30% humidity (preety low, i know)
31 - 08 - Seeds planted, kept the pellets moist (it's not that tricky at all) and -> 04 - 09 - Seeds sprouted.
Kept them under one 55w CFL until today. Now they are on 1000w MH standing at 90cm distance.
I am now transplating them in the pots, still not sure how to time the feeding. Heared that one dripper may not be enough later. They seem not to do a great job at watering the coco (the coco seems wet just in the spot the dripper is on, but i guess underneath the moist propagates.
I did not pre-wash the coco. I only watered it today for 10 minutes with a 1/4 nutrient based sollution. Usually i do not feed seedlings this young with any kind of nutes until they work their way to the 3rd set of leaves, but I understand that coco is a little bit different.
For the feeding, I was thinking 2 ways:
1: Feed them once every 1 or 2 days with a higher EC. (for 15 minutes)
or
2: Feed them 2/3 times a day with lights on, with e lower EC. (for 3-4 minutes?)
What do you think? I also need to waste as little nutes as i can.
