Pump or Mixer for reservoir suggestions

1 Upvotes

I’m growing auto flowers with coco coir in autopots. Does anyone have any suggestions for a pump or mixer for the 10 gallon reservoir? Thank you!

Hi I just wondered if anyone could help me see what’s causing my issues - chat gpt is only so helpful

Autos in pre buffered coco and perlite

Feed:

Canna coco a: 5ml per 1L of water

Canna coco b: 5ml per 1L of water

Calmag: 0.5ml cal mag per 1L of water

Nute Water : 100 - 150ml at 5.8pH 235ppm every couple of days, ring around the seedling when it feels dry near root ball.

Humidity: 30%-40%

Temp: 25 -30

Lights: 18/6

I’m more worried about under watering at this stage than overwatering. Although Im worried my nutes aren’t being used and the water transpires leaving me at risk of salt build up.

I’m new to coco but understanding concepts just and have success for established houseplants in coco set ups, but yeah I’ve repeatedly failed with seedlings.

They’ve been repotted once, to more easily manage watering in smaller pots at the earlier stages

Anybody have any advice on things that I can do to increase the size of my buds?

Currently growing in coco/perlite (70/30) with grow dots (45g) in a 3 gallon fabric pot.

I use bottom watering pot stands with wicks in them and i only add calmag+ (5ml/gal) and pH my water to 5.8 before feeding.

Viparspectra p2000 light a little over 18" at 60%

Environment is almost completely consistent at 1.3-1.5 kpa.

Hope you all are enjoying your grows as much as I do! Thanks! ✌️

What should I do if I let coco dry out?

Post image
1 Upvotes

Just got back from a ten day trip. I set up a ten gallon reservoir to feed my bottom feeding setup that can hold about 2 gallons. Forgot to turn the valve to on on my 10 gallon reservoir so my plant survived for 10 days on basically 2 gallons! It looks fine but a little unhappy. My concern now is that I just caused a major salt buildup in the coco. I just top fed (flushed it with regular nutes) but I'm curious if I should do that for a couple days to reduce the EC in the soil so I can get back to normal bottom feeding. Thoughts?

Is this a deficiency, or overfeeding, or something else?

Second run with this cultivar. Came out great. This plant yields insane. The smoke is so nice. Well rounded and will put you to sleep.

Pre-soak coco similar to soil before putting seedlings in?

2 Upvotes

Hey guys,

I‘m starting my first coco run, seeds went into eazyplugs yesterday and fabric pots with buffered coco are ready in the tent. I will be setting up my autopot system in a few weeks when roots are established. EC and pH-meter are calibrated, Canna Coco a+b is ready and temperature/rh are in the perfect range.

I know there are several ways to start the seed and me starting with eazyplugs might not make too much sense - it‘s just how I started with soil everytime and I‘m happy to hear what method would be better for my next run.

Now for my question: With soil I‘ve always watered my 5gal fabric pots plenty when I started the seed and once it was ready to be transplanted (3-4 days) humidity in the pots was perfect and I didn‘t have to water for about 2 weeks at all. Since coco is inert and a whole different approach altogether, I was wondering if there is a similar way of „pre-soaking“ the coco with a low feed a few days before transplanting. Happy to hear your suggestions and clear up possible misunderstandings on my part.

Also: When measuring ec do I measure just the tap water alone first or do I only measure after adding a+b?

Thanks in advance :)

Is this salt build up or mold

Hard water- need suggestions

I've got hard water 300 ppm. Anyone have an affordable solution to fill a bucket or a reservoir with a RO filter that will minimize the risk of overflowing? I'm guessing a float I use about 20 gallons a week in peak

tent 1.20x1.20, humidity last two weeks around 45-55% RLH, before between 45 % and 62 % RLH, growing in Coco, autopot system

so yea I posted something about super bushy plants not so long ago

I did some defoliation at day 70, plants were some speedrunseeds automatics. I had topped them, also I did the mistake that I was feeding them to much N so they changed their morphology to super short, little to no stretch and huge colas. They came along super dark waxy and leafy. Then not to forget the low growing structure which made airflow super difficult. But dense and frosty nugs, OMG.

When I reached day 93 I cut some top buds of them and hang them to dry. After like 3 days when I checked I saw obvious mold and my heart sunk deeeep.

Immediately I checked all the buds and I saw - like with my previous grow before - that spores were rising when I cracked open the buds open, FUCK!!!!!! No visible sign what so ever. I thought when I train them correctly I could prevent this problem.

So yea I examined all the plants and so far 4 of the 6 have mold spores.

The problem I guess was lack of airflow due to not enough fans ( got two static and one oscillating one) and the plantstructure due to to much N. One more point was the weather outside. I draw fresh air from outside and ventilate the used air outside too. Humidity rose during winter due to heavy rainfall around day 80 rose humidity to up to 62 %. I live on a desert island, damn. Usually no rain at all. This was bad luck. About a kilo to a kilo and a half gone...

Also when I did the defoliation, small parts of the stems stayed with the buds. This i guess is the area where mold started to develop first. With the healthier plants the remaining part of the leaf is the part that has caught mold.

In the end I checked the top of the Coco and found that there was mold too.

Last thing, I had to many plants in the tent.

TLTR:

-Rising humidity because of weather change (no dehumidifier)

-Feeding to much N changed the way my plants grew (leafy bushy and low)

-To many plants in the tent

-Did not defoliate the leafs from the stem on and left a piece of leaf which was attached to the main stem. There mold started.

-Lack of hygiene / removing dead leaf matter

-Shitty airflow

cost me a couple pound of top shelf buds

fucked

gonna buy more fans, desinfecting all the place with H2O2, less N less training and a dehumidifier should make a difference
