Sealed containers with H2O holds a large amount of thermal energy to be released at night without adding humidity. Also insulate your grow room and turn off venting/intake at light off to hold in heat. You can run your grow light at night and off in the day to offset temps, most people do this already but just in case you're not
I do all of this except the the thermal energy part
though I did a shitty job insulating cause clearly it doesn't hold heat as good as it should.. Or -18°c is just that cold (temp right now outside).
Might be. Just got parts needed to make my auto watering system, thinking doing 3-11 cycles a day. Would pot size still be a problem then, if it were before?
Yes. Your plants look like they’re running out of room to grow. This will introduce nutrient lockout. As far as auto-watering, I can’t really speak to that. My impression is the plant likes to be watered until it leaks out the bottom, and then allowed to dry over time. I’m always getting used to the weight of my pots before and after watering so I can keep waterings as infrequent as possible.
Noted. U grow in soil?
Yes, it’s a promix style medium, probably close to 40-50% perlite.
I see. Well I cant treat coco like soil, and generally pots for coco can be smaller than those for soil.
Have you taken a look at the roots? I’ve grown upwards of 100 plants in my life, maybe more. I’ve seen these problems a lot in the older plants I kept. By all means get a second opinion! If I’m growing it, I know everything. If I’m seeing something second hand through photos or video, I can only speculate based on my education and experience. Good luck!
No, what should I look for?
so u might be right on the nail here @Homegrown Hero
No worries! I don’t have any experience with coco, but will soon. From what I’ve seen, you place the coco medium in a pot, and the coco remains rigid. So I’m thinking you can pull the coco out of the pot and observe the roots. My guess, you pull the plant out of the pot and reveal heavy root mass. It’ll look like the roots have completely overtaken the medium, possibly swirling around in a circular pattern.No, what should I look for?
Yeah I saw ur operation man, not seconding ur experience
And btw cudos for reacting the appropriate way.
If I let it dry a bit more than it should I can easily pull it out(bcause or shrinking).
Check out the roots!
Ive grown 2lb plants from 3 gallon of coco without CO2. If you fertigate many times a day pot size is practically irrelevant for coco
Most of what your saying is incorrect for hydro coco. You may have 100 of plants under your belt, but you dont know about coco; you know about other grow mediums. Coco needs to be on a drip for optimal results and with drip systems instead of transplanting you just add more feedings. I feed 288 times a day; yes that number is correct.
Huh, that’s very different than what I’m used to. Thanks for clarifying. My apologies for any confusion I may have caused.
Thanks for chiming in. Any tips about fertigation? Using 5L pots atm (2x2' area each). I'm not sure how many times per day is best.
No harm done
