Hi,
I read that 3'x3' (9 sq ft) is the ideal size for a 400W HPS bulb (~45-50W/sqft).
However a 400W HPS bulb has around 60.000 lumens whereas a 400W MH bulb has around ~35.000-40.000, so roughly 33% less lumens.
Therefore I asked myself if the coverage area for a 400W MH woud drop by...
Hi,
could you please post a link to cannabis nutrient profiles or pictures if you know any.
For now I only know about three nutrient profiles and another one which doesn't seperate int he differen phases of the grow.
I attached the picture of two.
Thanks!
Hi,
I am using AN 3-part ph perfect fertilizer with R/O water and my plants developed a Magnesium and what it seems to be a Sulfur deficiency too.
After looking for the reasons I used this nutrient calculator.
By using this calculator I figured out that the AN fertilizer barely contains...
Re: Aeroponics, what kind of filter to prevent sprayers/nozzles from clogging?Mesh/Mi
I cut one of my nozzles open now and measured the orifice and it was exactly 2mm.
Hence I figured that I made a mistake by converting the .075" orifice of the EZ clone sprayers to mm.
They have a 0,19cm...
Hi,
my aero system is top feed and the nozzles are pointing down and are spraying the water downwards.
My roots are nearly touching the bottom of the grow chamber now (12" deep). The nozzles are adjustable vertically but currently they are at the highest position spraying just the netcups...
Hi,
I was wondering what kind of filters you are using to prevent your nozzles/sprayers from clogging.
If I am not mistaken all the large aeroponic manufacturers (GHE etc.) are only using foam type filters which are mounted on the pump if I am right?
Are these kind of foam filters (see...
Hi,
I am using RO water and I didn't used calmag or something similar for my plants.
Hence my plants developed deficiencies.
As calmag is not available in my location I bought Canna Mono Nutrients (Separate bottles of Magnesiums and Calcium).
I read that the Calcium to Magnesium...
Hi,
my plants have some Nitrogen deficiencies and I bought a bottle of Canna Mono Nitrogen.
The bottle states: Contains 27% N. (Contains: ammonium 6%, amid nitrogen 11% and nitrate 10%). Use 1-2ml/l.
I used 0.5ml/l and my EC rose from 1.2 to 1.6. As it was a bit high for my taste I...
Thanks for this detailed reply! Appreciate your help. My growroom is 13x13x9 ft and currently the air is getting exchanged at around 10 times per hour. Temperatures are 21° C during night, 25° C during day at canopy level, and around 22° during day in the room. The humidifier which I can buy...
Hi,
right now the winter air is very dry here. Around 20% outside of my growroom and 35% inside of my grow room.
How do you guys increase the humidity? I already placed all of my dishes and cups with a bit of water in my grow room.
I am also placing wet towels on my aircooled hoods...
Thanks for all the support so far!
Before moving my plants (were just in rockwool cubes previously) to the aero system I watered them by hand from the bottom with EC 1.0 and PH 5.7 once a day.
The plants are 90 days old now since they germinated from seed and went through some trouble, hence...
Hi,
my plants have plenty of yellow leafes.
What kind of deficiency do they seem to have?
I checked abuse charts and it looks either like a nitrogen or sulfur deficiency to me.
The leaf stems are purple.
Please check attached picture.
I hope you can help me.
Here a high res picture:
Hello,
I am about to finish my aero system and I would like to know if the PVC piping size looks OK before I glue everything together.
I have 39 sprayers (160l/h / 4.2gl/h) which equal 6240l/h or 1642gl/h in total. I have a 6500l/h main pump which will feed the sprayers and a 3000l/h secondary...
Hello,
I intend to use 38 nutriculture 160l/h (brown) sprayers for my diy aeroponic system.
Now I am wondering how many l/h the pump should be able to deliver.
I thought about using a 2800l/h pump, however if I multiply 38 sprayery by 160l/h it results in 6080l/h.
So do I need a...
Hello,
my tapwater has a high EC of 0.8 and a PH of 8.0.
I am wondering if I should take this baseline / backround EC into account in hydroponics or not?
I was looking for an answer and some say to ignore it, some say to take it fully and some take only half of the baseline EC into...
