Dinafem - Quick Critical+

There is a very strong and tasty smell in the air. Skunk and citrus aromas are dominant. :smoke:

As substrate I use soil, which is only slightly pre-fertilized.

The lighting system is the Sylvania Grolux Linear LED 396W.

The plants get pure osmosis water and nutrient salts (NPK 18-12-18). The dosage is 4g / 10L, with CalMag 7ml / 10L.

Additionally some MKP (1-2g / 10L) now.

The plants are in flowering day 39, they could be ready for harvest with 52 days of flowering, let's see. :joint:

Flowering, Day 53

Flowering, Day 53

It was a selection grow and I found my new keeper. :)

At 53 days they were ready and the harvest started.

And it continues with the Critical's.



This grow area is 2.4m x 1.2m.

With conventional lighting (2x600W HPS) I placed 32 plants in the tent.

Now with the LED systems I only put 28 plants in the tent.



I observed that it did a lot better. Due to the very good depth effect of the LED systems, it makes sense to give the side branches of the plant more space.

This allows the plants to reach their full potential.



Some relevant background information.


My water value from tap water:

EC = 0.4

Carbonate hardness = 5-6 °dH



My water values ??from pure osmosis water:

EC = 0.0

Carbonate hardness = 1-2 °dH



Fertilizer Salt

NPK (Mg) 18 + 12 + 18 + (2.4)
with
NO3: NH4 ratio 57:43, balanced.


This nutrient salt is perfect for my soil and coco grows because my water has a carbonate hardness of less than 8.4 °dH.


I only use this nutrient salt as main fertilizer, from the cutting to full bloom, with the addition of ATA CalMag (5-7ml / 10L).

From about flowering day 30, add some MKP (1-2g / 10L).


My nutrient salt concentration here on soil is 0.4 to 0.5 ‰.

This corresponds to an addition of fertilizer salt 4-5g per 10 liters.



The conductivity increases by 0.57 - 0.72 EC.

These ladies stand in coco soil and under conventional lighting (HPS).
