Dabney Blueberry 800w cmh/hps rockwool bucket scrog - Grow Diaries - International Cannagraphic Magazine Forums

Cannabean · 08-15-2008, 05:30 AM

I was convinced to try rockwool buckets instead of dwc so lets have a go at it.

I went to lowes, bought 5x10' pvc pipe, bunch of 3/4" adapters, both size cement tubs Lowes offers, 3x 5gal buckets, and 2" cement reinforcement grate for the scrog, total ~ $65. Im trying to keep it as diy as possible.

One $40 bale of grodan shredded rockwool filled the buckets with about 2/3 left over.
I soaked the rockwool overnight in ph 5.5 r/o water.
Drilled some drainage holes in the buckets.

Filled the buckets with the soaking rockwool and let it drain

ph'd the runoff and flooded the buckets one more time with ph5.5 and let it drain

Backfilled the dabney babies in

ph 5.5 ppm 350

Like I said I have no experience with rockwool buckets whatsoever

Any and all help will be appreciated.
I'll do a diy for the flood/drain table+scrog with parts list and measurements if there is some interest but its very similar to Levitikuz's ebb tables: https://www.icmag.com/ic/showthread.php?t=70262

rockwool growers please stop by and say hi

Shotgun.......Can't wait to see how it turns out. Good luck Canna.

At first glance I thought that bucket full of shredded rockwool on the second pic was buds. Ha. Good luck on this run Canna. I'll surely be lurking somewhere in the background. Have fun

i only see one light... do you have 2 - 400w wired up or is there actually an 800 watt lamp avail that im unaware of?

Cannabean · 08-15-2008, 03:29 PM

thanks for stopping by fellas.

JustinCase: haha I wish that bucket was full of buds!

Papulz: they are vegging under one 400w cmh right now, another 400w cmh will be turn on near flowering, 800w hps will be swapped in for flowering.

This is an excellent method of growing! I had great results with it.
First tip - cover up the rockwool with some hydroton clay balls or pieces of poly. It will soon be green and slimy otherwise.

Cannabean · 08-28-2008, 04:29 AM

Thanks NGB!

: I added the hydroton and am happy I did, it helps the rockwool get equally wet since I'm handwatering these buckets.

quick update today, still veggin, and will be for a while.

ppm 550
ph 5.4

comments/questions/tips welcome

Absolutely text book my man. Are those plants all female - or have you yet to find out?
What brand of nutes are you using? The plants are so healthy

Something for you to try in the future: Put an airstone in the very bottom of each pot then have a 2" layer of hydroton before filling the rest with rockwool cubes. I had awesome results doing this. When i used to hand feed them the pots would be sitting in about an inch of nutes in the tray. The airstones in the pots would be bubbling it all up and the growth was explosive. Have a looksee at the link in my signature to see for yourself.
I think you'll do exceptionally well on this run, and it'll be alot less hassle than dwc!

Edit - here's what i mean about the airstone:
