Learning as much as I can as I'm growing fruit trees and a vegetable garden too.
All and any advice is welcome!
I thought on putting them straight in the dirt, but then thought of the convenience of using big pots: if the need arises to be able to move the plants. Thinking on getting 40L baskets (espuertas)
to use as definitive pots. Should them be bigger?
The soil clay content is rather high, as I'm really close to a river.
It is really rich soil, full of nutes (this soil has been worked on organically on recent years) I had to deal at weed out time with impressive tall nettles, ground carpeted full of yellow oxalis (clovers) flowers, tons of Zantedeschia aethiopica growing wild too.
I thought on ammending the (ground) soil in the final pots with a high peat content, light soil, 50/50 to ease drainage. Maybe a thin layer of compost as dressing on the top on the final pots?
From what I've read at ACE's descriptions, looks like no additional fertilization will be needed?
I guess is the right time to start the (regular) seeds indoors, how should I harden them once I bring them outdoors (thinking that would be by the end of May)? Leaving them at the shadow several days?
I usually repot and use dry/wet cycles in coco.
I thought on starting them in coco (easier for me indoors), then move to soil when bringing them outdoors. Or should I sow in soil from the beggining?
Thanks for choosing our genetics for your first outdoor grow
Correct me if i'm wrong, you are planning to grow them in pots and not directly in the ground. One of the main failures that outdoor growers when growing with small/medium pots do (especially in hot terraces like in south of Spain) is to provide the plants too big pots when they are growing, so the plants have a great growth, but later when they are about to flower the grower doesn't transplant them again with the fear that the plants get too big ... then the plants suffer from ph unbalance, salt saturation and from lack of new nutrients and lack of new space for the roots in the most important moment of the cycle: when the plants are flowering.
My main recommendation regarding pot size and transplantings would be to start them in medium sized pots during their growth, and only transplant to final bigger pot when they start to flower, so plants have all the new nutrients and space for the roots to use them for flowering stage.
Clay is not the best soil for growing cannabis, the clay becomes too hard when it is dry and the ph of clay is usually very high. If you are growing in pots then i would recommend you to use a soil based on mainly high quality peat (90 %) with a bit of worm casting (10%) for the growing stage, you can add perlite to improve soil aeration or vermiculite to improve the retention of water of your soil. For the flowering transplant add guano in powder.
Another key factor when growing in pots is the use of clean high quality water (rain water or osmotic water) and to water/feed always in the correct ph range for soil (6.5-6.8).
Lebanese, Ethiopia and Honduras are sativas with low/mild fertilizer requirements. Start them in their first weeks of life with a soft soil mix (peat + coco fiber for example), after 1 month of life they will start to enjoy richer soils (peat + worm casting), until then the soil will provide most of the nutrients they need, so you won't probably need to fertilize in their first month and half of life. You can fertilize them when plants pass the seedling stage, but usually at third or half dosage than the recommended by the fertilizer company.
It's always recommended to fertilize a bit in the first 2/3 parts of the flowering to increase yield.
Take also in consideration that Lebanese will start to flower around first half of July while Honduras and Ethiopian will start to flower around mid September, so plan accordingly.
I would start/plant them directly outdoors in the place you plan to develop your grow. I don't see any benefit starting them indoors. Just protect the seedlings in their first days of life from the intense mid day sun and from excessive heat from the ground of the terrace (typical in summer in our country).
Hope it helps, feel free to ask any doubt you could have during their development.
