How do you find coco bro? Iv been looking at alternative mediums, and now I have a good ph pen
Anything you need to look out and keep an eye on in coco?
I've only done 1 grow in soil before moving to coco, and now again with this biobizz thing. To answer that question right now would defeat the whole purpose of this thread and my autoX thread :brow: but stay tuned for a final report :smokebuds:
About what to look out for... well, there is a half-dozen types of coco. For reptiles, for conditioning, as medium by itself, washed, unwashed, buffered or not, with trichoderma or not etc etc. So just go straight to the known brands no matter what you local store says. Biobizz, Canna and others have specific coco products for our needs, and silly money compared to what might go wrong (I almost killed 7 seedlings once!) - around 15€ for 50L of proper, ready to use coco.
Coco is basically hydro, so get that pH around 5.7/5.8 in veg and up to 6.1/6.3 in flower - dont get too paranoid, you don't have to nail it everytime, in fact, its better if you don't. Coco relies a lot on Cation Exchange Capacity (CEC), highly pH dependent, so swinging the pH slightly is actually good for nutrient uptake. CEC is also the reason why there is no separate veg and bloom nutes. Just A&B.
Get airpots! Especially with coco! Very noticeable performance boost. Watering is still very debatable. People swear by feeding once daily, or multiple drip feedings a day, I prefer to let it dry out a little to keep the roots in shape. 24h before planting the seed, rootling or clone, water the coco with an EC of 0.6 and pH 5.5 until a little run-off comes out. This will kick start life before planting and seedlings who prefer a slightly more acidic environment to start out. This is not pure hydro, this pH 5.5 will interact with the coco positively.
Clean the pH probe and calibrate once a month, like a religion.
What else? Oh, first 2 weeks, water daily with as little as you can actually bear to give loool ... this will highly encourage the roots to shoot downwards looking for more. If it goes well, you will freak out because the top side of the plant will look like its stunted in comparison to soil grows. This is because the plant is redirecting all energy to root production. Once it finds its limit, then BOOM, upwards explosive growth. So a good idea to pot directly into the final container.
Cant think of anything else right now, its pretty simple. I'm pulling up 20L litre airpots this next run, so I hope to get close to what people do with buckets and bubbles!
Definitely try it! You'll love it Kipster!
