Coco Growbag Support
Below is two different guidelines for using Coco Growbags. These come from experienced growers who have been using Millenniumsoils Coir Growbags for many years. Keep in mind that these are all guidelines, and there will be variations depending upon your greenhouse, and location.
Guidelines for Millenniumsoils Coir Growbags
Preparing a fertilizer plan:
- Fill a couple of slabs with clean water.
- Let those stand for 24-hours.
- Drain those slabs.
- 2 hours after draining ad some clean water on those slabs.
- Catch this drain water for a water analysis.
Based on those numbers you make a fertilizer plan, without Potassium and approximately 15% extra Iron and Manganese. Keep in mind the need for more Calcium.
- Fill the slabs with this fertilizer plan.
- Drip with an EC from 1.8 till 2.0 and pH from 5.6.
- Drip till the slabs are saturated, or even a little bit overflowing out of the plant holes.
- Drain the slabs after 12 to 24 hours.
- Make sure that there are enough drain holes in the slabs, 1 between every plant, 1 at begin and end of the slab.
- Drip after that, 1 litre a plant / dripper, with an EC value (fertilizer plan), which you like to start off in the crop.
Bring 35% from the Potassium back in the fertilizer plan (based on a regular fertilizer plan).
Start off with a 0.2 higher drip EC.
Send after 2 weeks a new water sample out.
Make a new fertilizer plan on those results.
Give after planting in begin frequent water (short shots), so you prevent drying out of the blocks through the coco slabs.
When necessary to control the plant, you can stop with dripping water for a couple of days, when the plants are fully rooted in.
During the season:
Drip during the season with longer drip rounds.
Put always extra (15%) Iron and Manganese in.
Keep an eye on the 1st drain of the day, coco start draining when it is 100% saturated, this means coco drains average later (rock wool drains a little gradually).
Coco has over the average a higher pH (don't worry).
The plants grow on the average more vegetative on coco; adjust your climate to it.
Drip the double concentration of a pesticide on coco then rock wool, when you have to use it, because the organic structure of the slab, coco binds pesticide.
Stop on the average a little bit earlier with dripping at the end of the day compared to rock wool.Information above is provided solely for the user's information and, while thought to be accurate, is provided strictly "as is" and without warranty of any kind, either express or implied.
