Grow Mediums When do you start feeding nutes in Coco and how much?

It will depend on your pot size, pot material, and whether it’s pure coco or cut with perlite/pebbles.

Here’s my week 1 method:
- Precharge coco with mild nutes + calmag 2 days before dropping seeds.
- Drop seed into coco 1/4”-1/2” down and lightly cover with coco.
- Put a humidity dome over seed, and mist coco once a day.
- Keep your temps above 80°f and humidity around 60-65%
- Usually 48hrs after seed drop you will have a seedling.
- Remove humidity dome to let it breathe.
- I only use RO water with 150ppm of cal mag for the first 7 days or so. Usually day 2-3, and 5-6 I give them abit (depends on your pot size). Don’t soak your pots for the first few days, let the plant get it’s roots under her first.
-Day 7-8 start fertigating with your nutes everyday
- I make sure to start getting 15-20% runoff by week 2-3.

Fairly vague I know, but there’s no cookie cutter one and done amount to feed in the beginning, theres just too many variables.
 
thanks for the prompt responses! feeling less scared now.
 
Although vague, an excellent starting point for most of us going into coco.

I picked up 4 bricks of Canna Coco this afternoon.
My intention is to transplant my 7 seedlings presently started in double solos ( Sunshine4 in the solos).

So,I'm going from soil to coco in the transplant once the seedlings have the roots ready to move.

My question now is, ..
Canna claim their coco is preconditioned etc...etc..
What does experience and reality say from the more experieced users?

How much calmag and nutes go into the prebuffer while soaking the bricks?

Cheers fellas, this is a great thread!:cheers:

I don't use Canna, but this thread might give you the answer:
https://www.autoflower.org/threads/canna-coco-growing-tips.29173/ ... seems the OP hasn't used coco in while, though.
 
Lots of info on cocoforcannabis dot com too.


For germination, you have to keep the temps above 80F. Not optional if you want consistent results, and this can be a challenge if you germinate in full pots.

Good luck with the grow. :goodluck:

if room temps are lower than that, would using warm water help to compensate or not a good idea ?

Not a good idea. You would be better off starting them in a smaller cup that can be kept at temp for sure, and then transplanting. Temperature is likely the biggest deal of the bunch with germination. The babies do not like cold, and cold for them starts at ~80F. If you follow the instructions put on here by @slowandeasy, you will be golden. See https://www.autoflower.org/threads/germination-issues-please-read.74468/page-2#post-2228728 for good info. Don't let anyone tell you that autoflowers won't transplant, that is bs. Not one of the ones I have done have hiccuped in the slightest, and I am a noob at this. Get them started strong, leave them long enough on their initial cups to develop a good root wad, and they will be just fine. Just follow Slow's process rigorously and you will be far better off than trying to germinate under cool temps in your final pots.

If you really want to avoid transplanting, you need to pre-warm your final pots in the tent until they stay at 80-85F consistently before planting. This will take a day or two, not just a couple hours. If you are starting in a room rather than a tent, you should heat the whole room with a small electric heater. Whatever, you gotta keep them warm from the get go until they get growing well, or your germination success will suffer, maybe a lot.

If you haven't already done, have a look at cocoforcannabis dot com before diving in - there is a huge amount of good information there. Plan on using some cal-mag of some sort with your grow even if the coco you are using is already buffered. If it was me, unless other growers here can confirm that your exact coco product works well without it, I would rinse and buffer anyway. Not much to lose because buffering again will not hurt anything, and a whole lot to gain if you avoid problems later. Coco is not dirt, it is pretty much hydroponics that looks like dirt. And it eats calcium and magnesium. The initial buffering loads up the hungry sites in the coco material so that the stuff you provide later is available to the plants. More hungry sites develop later in the grow as the coco breaks down, so you have to keep feeding the coco as well as the plants. Apparently, LED's also add to the need for cal mag.

Good luck with the new grow, and keep asking questions - there is lots of friendly help here. :pighug:

Thanks for sharing the experience of an OLD FART,.. :woohoo1:

I've actually lost seeds after the soak in a shot glass, because the soil (Promix) wasn't hot enough.
Germination basicaly stopped and I lost the seeds (7 x $5)...Shyzer:doh:

So having learnt this the hard way.
I now have my seeds in the shot glass on a heated mat (set to 27c...roughly 84f).
Then transfer to double solo cups ,....and placed into a dome ( all still on the heated mat).
I use LEDs while under the dome, and adjust my height to adjust for heat (25-29c).
Plants love this approach and don't stretch.

Sounds like you got'er dialed. Temperature may not be everything, but it is bloody close. Too bad about the lost seeds. I consider myself really lucky to have avoided that outcome while learning this stuff. Mostly accident, but I'll take it, and now I know better. Next grow will be with Slow's process.

Happy growing, however you keep those babies happy! :cheers:
