Anyone using blumats in coco?

Shoot fellers, this is getting complicated now... lol

 

@NezAI have to have the lid off my res, to keep my nutes mixing with the wee pump i have...Theres a cable so I cant close the lid, and I wasn't going to butcher my lid, or tank top edge...pressure?, surely the water drop weight creates its own pressure?

 

@Rural Buddhaand 20% perlite too..., did you create a pure coco 'pocket' for the sensor? Earlier in the thread we discussed perlite, and some folk said the contact was interrupted by the perlite, which lead to 'complications'...Im gonna have a read through your diary my friend.

No pocket zeroG, didn't see that or forgot about it. If the Blumats doesn't work properly I'll pull them and go back to hand watering and make a pocket next time, I didn't plan Blumats when I started this Air-Pot grow.

 

I think Blumat were talking atmospheric pressure rather than tank/water pressure. I wonder if a too well fitting lid might cause a vacuum - unlikely I think. I too have a small pump to keep the nutes mixed and have the lid ajar because of the cable.

The rationale behind my thinking is a few posts back in here @zeroG if you set them up with the lid off and you keep the lid off it won't cause an issue. I set mine up with the lid on so when I left it off I think that difference in pressure from the extra airflow was enough to cause a runaway. The system is incredibly sensitive so it is possible I guess. Anyway it's just a suspicion I'm still learning about these things so it's all speculation on my part.

@NezAits all speculation and conjecture my friend - I found the best use was to support the system, some days the units worked falwlessly, i would walk in and see drips galore, wet coco, heavy pots...all good brah!...

 

next day i would walk in and nothing, nada, nish, not a drip of solution to coco to the point of powdery dry medium at times and I'd have to jug out the solution from the res to the pots by hand... lol

 

Some days it was like having a dog and chasing the postman and barking at the garden myself...

48 hours from installing the Blumats and girls looking OK. As per the instructions I gave the pots a good watering, run-off around 15%, then set the drip knob as per instructions. I was expecting some drop in the tank as the girls drank but none occurred in the first 36 hours. Girls looking OK, perhaps a daily feed wasn't necessary, though they usually looked a bit droopy when they had their late evening feed and were perked up by the morning.

 

This morning as the coco was looking a bit dry on top I fiddled around with the drip setting so that a drip falls around every 10 seconds - some drippers faster or slower - the 3rd (last) dripper on Shorty needed to pulled up higher to get it to drip at all. The feed tank has dropped by around 2lt in the last 9 hours or so, I'll leave it like this and see how it goes.

84 hours after installing Blumats.

 

Girls still looking OK, not drinking much from tank though and coco looking dry on top. I check every 3-4 hours to see if the dripper are dripping - sometimes they are, sometimes not.

 

The feed in the tank is now a bit old so am considering alternatives to such a large tank taking so much space when it may be bigger then needed - it can hold 35l but I only put in around 12l.

I don't drink tea, I try not to drink too much coffee so my 'staple' drink is Ribena (I'm a big kid :) ). I have kept a few empty 1.5l bottles for various uses so had a look to see if I could use one or more as feed tanks. The Blumat tank fitting fit perfectly in a Ribena bottle lid! I found the 'bottle knot' on several websites and YT and eventually got my head around tying it - perfect for the job. Now I'm thinking to hang the bottle(s) outside the tent so the feed doesn't cook, it should warm enough as it passes through the pipework inside the tent so the girls don't get cold drinks. Just got to work out a way to hang the bottle up, thinking hooks in the ceiling once I've worked out where the joists are.

 

Comments and suggestions very welcome.

 

Closed bottle to test if cap is water tight, seems to be. Bottle also has hole in bottom (now top) to be able to fill and also to avoid creating a vacuum as bottle empties.
