I am limited in pot size by the containers compatible with the AutoPot system…
I could possibly get around this by running more plants though. The Ecothrive website gives recommendations for a 1.2m² footprint (my tent
) of: 2x 80L pots, 4x 40L pots or 9x 20L pots.
I have 15 & 19L pots, however there is a 25L plastic pot available (as well as a mad 4’x4’ tray system which holds five massive pots that I am not buying
).
Do you think a 19L or 25L pot of straight Ecothrive or Sohum soil would see a plant through an entire cycle - Based on 9x plants, scrogged in a 4’x4’ tent with probably 4 weeks from seed until flip & then 70 days until the chop?
Regarding the amendments Living Soils (living soils fertiliser dot internet) have organic grow Grow & Bloom fertiliser mixes:
Grow:
Key ingredients - EM1 infused bokashi bran, Volcanic rockdust, Mycorrhizal fungi, Alfalfa meal, Mealworm & black soldier fly frass, Wheat bran.
Nutrient analysis
Total Nitrogen (N) .........4.0%
Phosphorous (P) …….....6.0%
Potassium (K) …………….4.0%
In this blend we have added 18 different species of mycorrhizal fungi to assist with reaching and processing all available nutrients in your substrate. We've also added powdered volcanic rockdust (which contains two thirds of all non-synthetic minerals known to man) to provide heaps of essential trace elements.
Grow will assist your plant throughout the vegetative stage, ensuring it develops rapidly and without deficiency. For maximum nitrogen we include loads of insect frass, blood meal and alfalfa meal as well as EM1 infused bokashi bran to further encourage microbial life.
Using Grow from the beginning of the vegetative stage will maximise yield and improve aroma and taste of your plants' flowers whilst ensuring the requirements for additional fertilisers are dramatically reduced. The NPK is similar to the 444 provided by other companies, but has slightly more P.
Mix 3-5 ml per litre of soil (or 1 tablespoon/ gallon) (double this for coco) - ideally 2 weeks before planting. If already planted up, incorporate it as a top dressing: add it to the top of your growing medium and water in well after application. This will provide enough nutrients for 3 to 4 weeks of vegetative growth.
Bloom:
Key ingredients: Organic Bat guano, Organic Scottish Seaweed, Sterilised bone meal, Soybean meal, Mined sulphate of potash.
Nutrient analysis
Total Nitrogen (N) ........2.0%
Phosphorous (P) ……....4.0%
Potassium (K) ……………6.0%
This unique mix has been specifically developed to increase the size, taste and aroma of your photoperiod plant’s flowers plus provide it with enough Nitrogen to stimulate growth during the stretch phase.
The phosphorous and potassium in this blend have been maximised via incorporating seaweed meal, bat guano, wheat bran and mined potassium sulphate. It’s particularly effective in organic cultivation when our Grow mix has been used in the vegetative stage.
I figured amend with the above to try & get through a full run with water only.
However it’s not like I don’t top water the AutoPots anyway so keeping the top of the soil moist to keep the microbes up there active & I’d be adding tea’s too so perhaps top dressing isn't actually an issue a issue, now I think about it
I was trying to be funny regarding the soil EC meter, was a nod to my current method
. I’d get my coat, but I no longer have one as I’ve been losing the shirt off my back, these last few months
Thank you for the information, the main reason for this idea was as I am limited on pot size, although I didn’t mention that. I actually figured the layering thing would be common practice, however I’ve never grown in soil before so it’s all still quite alien.
