So if i understand correctly in veg does not need to watering to runoff. But i have a question. If i keep the top moist daily does not will be the bottom dry after a x period? Or it will wicking the moisture down?
the plants will dry out if you only water a little bit a day to keep em moist but they will dry out slower and the roots near the top will grow more. the roots nearest the top are for sucking up food, the lower roots are mainly for sucking up water. so if you give a good watering then keep the top lightly moist it will help generate a stronger bigger root system. so instead of letting em dry out completely and watering every 3-4 days, water once to get a bit of runoff. then water lightly daily to keep the top moist and then water fully after they dry again and repeat. the roots seek moisture which is what makes them grow and expand. so while wet dry cycle is good for tiny seedlings and after a fresh transplant, i find the best root growth by doing the soaking then keeping moist till they need another soaking leads to overall faster thicker root growth. as far as coco is concerned. once they get rootbound enough for multiple feedings a day the growth is explosive. that dtw coco thread is a great read.
You can't agree because?I'm sorry but no runoff? Can't agree with that at all. I recommend to water to runoff at least daily, but it depends on size of pot. The idea is to have constant fresh nutrient supply and flush out old nutrient build ups. I've done 2 daily feedings in 1 gal pots in veg and noticed pretty quick growth. But 1 daily should do the trick as well, as long as you get about 10% runoff or more.
Leaching works well but I feel bad polluting for no good reason, since it's easy to get the same results by adjusting a few parameters.
need more oxygen? => grow in smaller container and feed more often
eliminate salt build up? => feed at lower EC in the first place
need to automate your tent? => blumat all the way
When I see the nonexistent rootmass in those pictures, and people advising daily (or more!!) feed with runoff when the plant is starving for Mg... you guys know that you can drown a plant, even in coco.
OK, thank you. I sprayed them and raised the lamp. When the leafs are dry i will lower it again. Can i do it again tomorrow?
And please lets talk about the nute strength. So my tap water is 0.5 EC (or 260 ppm). I add nutes (400 ppm/ 0.8EC?? is this enough or strong) till 1.3 EC (660 ppm) + 0.3 gr/liter Epsom. Or the Epsom is in the total 1.3 EC?
I hope you understand what i want to ask.
Hy ibreza and Miraculous Meds,
thank you for your help so far. Especially for you ibreza, because you have 6 post and just 5 in my thread. I hope you will not angry with me.
It seems to be Miraculous Meds has right. It is overwatering and this is causing my major problem, but after 5-6 days the smaller plants are not dry enough. And the others don't healthy too.
So i made a hard decision because this makes no sense at all. I know i am impatient but i don't want to spend more time on them.
My plan is the following:
- I want to buy a fresh bag coco which is not so fine. This Plagron is like a mud (maybe i should have used perlite). I lean towards Canna Professional Plus, but i didn't see it in real life so i don't know the consistency.
- I want to change nutes too. Canna Coco A+B, because this is fact it is designed for tap water and everybody is familiar with it. So if you want to help me it will be easier for you aswell.
- I will make cuttings from each plant and if they rooted out i will toss the old ones and start over with the clones.
What do you think guys? Which coco brand is not so fine? I can access everything from Servovendi (this is a growshop in Europe and they carry Plagron, Bcuzz, Atami, H&G, Canna etc.).
And i want a suggestion about using perlite. It is a must in my situation or not?
ps: The enviroment is spot and. I always followed the VPD and the fan is light breezing the plants.
