Hey Stunger, long time! or so it seems...This grow is now completed. I will try to wrap up what I have learnt from it.
- Watering; because I was trying for a fully organic grow, I feel I was overly mindful in keeping the soil watered to keep the soil biology alive, and because my containers had been converted to airpots I felt that there was no risk of excess water as they were very free draining. However, never did the plants wilt from needing watering. The general view seems to be to let the plants have some water stress during the grow. I now feel I should have allowed this to occur, as on a previous grow from the unintentional circumstances of a late outdoor grow combined with a too small container and periods of my absence that resulted in the plant going thru multiple 'wiltings' (one of which I was very surprised that it was able to recover), that particular plant produced amazing quantities of sticky resin and a fantastic intense high that I felt was from the watering stress the plant suffered, of course it may have been from genetics, but it is my gut feeling that it was from the watering drought periods it received. Anyway, next grow I'll attempt to go back to this approach.
I've read comments about watering on various fora that say let the plants dry out. The reason given is usually air to the roots (let the soil dry out to "knuckle-deep" at least before watering again).
Maybe a bit of "water stress" as you say is good for the strength of the finished weed, too. Reminds me of supercropping.
As you know, supercropping involves partially destroying the plant (crushing stems, bending, breaking) and then letting the plant recover and strengthen, the thinking being that, like in the wild when a plant is partially destroyed or eaten or crushed, it compensates for the injury by strengthening the injured part and increasing trichome production to increase its chances of reproduction. The "threat of destruction" stimulates the plant's efforts to reproduce. The plant comes bouncing back better than ever.
Water stress in the sense you mention is not about air to the roots but more like supercropping, i.e., stress the plant by depriving it of water and it will produce better weed. That is new to me and sounds interesting. I would be concerned that if taken to extremes, water stress might stress the plant so much it could produce a hermie or self-pollination. If you are present at all times and can monitor the level of water stress, it might work, especially in a small pot where the plant can use up all the water more quickly.
In my new 2019 balcony grow, watering is Sundays and Thursdays, about 1 gallon through drip line to each of the six plants. The 15 gal fabric pots do not ever dry out completely, even down to a knuckle. Water stress would be too risky for me since I am hardly there to monitor.
Greetings and hope you are enjoying the latest crop. How is it?
