Hi! This is a diary "economical grower!"
I will grow Jack Herer fem. My growroom's size 1000х1500cm. I will use 3 HID, 1300m3 S & P fan, carbon filter 1000m3, SPC controller, 6x 26l boxes with mapito (I use it for the 4-th time), blower fan, 2 humidifiers, thermometer-hygrometer and 85l of the solution.
Fertilizers:
- Nutri Nova A+B
- Mono Ca-5% (Canna)
- PK-13/14 (ANA- B)
- ANA-Roots
- Bio-Nova X-Cel
- Hesi Supervit
The 4th day of the mode 12/12 (1.6ЕС, РН 5.8 )
Few details about watering ... Mix a solution of EC 1.6 pH 5.8. After the solution was pumped back into the tank, I measured parameters again. If EC is 1.6 and pH is 5.9 everything is normal, it is not necessary to raise the concentration of the solution.
Early I grew using dwc, then E&F with exclay, drip irrigation with vermiculite, then I had problem with coconut (althouhg, many grow good with it), then I tried Grodan wool and it was good. After such experience I’m always near the wool. Theoretically salting shouldn’t be, though I can’t say how often have to flood.
I know growers who grow just on salts. There is no magic with calculator. One bag of 25 kg per 5000 liters of solution is enough. No additional sulphate, nitrate and other crap. All in one bag. Agrochemical for greenhouse with tomatoes. In general, complex fertilizer is salts with water, it is just diluted and bottled with a beautiful label. But I'm lazy, I prefer to pour from the bottle.
Instead 1ml of РК, add to the solution 0,5ml of PK and 0,5ml K
The total concentration is 1.9 ЕС, РН 5.8
The return is 1.98 ЕС, РН 5.8
As I said earlier, some bushes bloom faster than others, but I will keep them 2 weeks more. The simple rule – if cones have white hairs it’s mean they can grow up more. During 2 weeks the second blooming will appear – size of calyxes. We will meet it completely naked.
