Show me your stones

[Horsemanrocks]

I compared those 3 new stones and they were all similar, +/ - maybe 5%. One had a "lean" area in the middle (slightly more bubbles from the ends) but probably nothing I'd have noticed if I weren't looking real close. Total airflow seemed similar between the 3 stones.

Good score Hermieâ?¦..thatâ??s exactly the kind of information that I was looking for. With luck Iâ??ll be able to track them down onlineâ?¦..a picture is always worth $0.98

But check it out: I tried to "tee" 2 airstones off the same air line, and 90% of the bubbles come out of the stone that's only 5% better in a one-to-one comparison. Obviously, the air's gonna take the path of least resistance, but I would have guessed they'd "share" better. Pneumatics noob, here...

Yeah, I never had any luck w/ Tâ??s either. The picture that I used at the top is old newsâ?¦.the tray already has 4 separate lines in (the tees are history)

Punching your own holes in an airline for your pre-veg bubbler might be your best bet for even bubble distribution from a single air source. I would do it under operating conditions, though -- under water -- and start punching from the end furthest the pump. Evenly spaced holes are not gonna give you even bubbles in this instance. (Though, as W. pointed out, that doesn't seem real critical. I've got a 5" airstone, off-center, in a 5 gal bucket and it's doing a fine job, with even root growth despite the uneven bubble distribution and mid-80's temps.)

Hope it doesnâ??t get down to thatâ?¦.but you never know, could be valuable for a retentive kind of guy. Hmmmâ?¦..what size drill bitâ?¦.hmmm.

And how deep is that water gonna be? I think the bubbles will oxygenate the water better if they have to travel through it for a ways...

Well in the buckets about 8â?� deep (plenty of travel there) In the pre-veg only about 1 ½â?� at best. Still Iâ??m pretty unconcerned with (4) 6â?� stones in 2 ½ gallons.

Golly gee DHâ?¦..or maybe it should be â??uncleâ?� DHâ?¦..Gracias amigo

I don't really have any experience with the tube, jsut thought it would work good for your set-up, seeing as it comes in assorted lengths. But with the 1" stones, they are very consistent, just place one either under each plant or in between to save a dollar or so.

Thanks for getting back Forgetâ?¦..I may end up there yet

whats the MoV?

My attempt to not disclose anything that you held privateâ?¦â?¦forgetaboutit. If it didnâ??t make any sense to you then it was my error.
