Penetration to the bottom of the buckets was my main concern with the angled intakes. I think I just need to be watchful of the roots and rotate the lids. This being my first bio-bucket grow I think I will stick to BT's method until I get one under my belt.
The problem with the drawing is the water doesn't necessarily circulated like that after a few of weeks of root growth . With the supply at the bottom of the buckets, the root growth in a Bio-Bucket or DWC will slow or stop all the circulation to the top of the buckets. It might even cause more roots to flow into the drain line, because the supply flow is pushing roots towards the surface.
Water at the top of buckets will have the highest O2 exchange and forcing it down to the bottom will have the greatest impact.
Having the supply at the bottom of the buckets doesn't improve Bio-Buckets design and might cause more issues. The BigToke design with supplies at the top is proven, stick with the original. Just my 2 cents
I've been following this thread for awhile and I'd like to get a question answered from those experienced with bio buckets.
I've found the red lave rocks in sizes from 1 inch to 1/4 inch in size.
Does anyone know the best size to use for this system?
Though I have never tried it, I believe that come from the diffrent rates diffrent strains feed at, IE heavy feeders/ light feeders depending on strain. That would be hard to control on a single res recycling system like the bio-buckets. Big toke did it though if you will backtrack a bit and read earlier posts of his, he mentions the strains he grew, but I think he said he wouldn't do it again. I made the mistake of flowering a bit late, my fucking 8x11x7 ft. room is curently a jungle, I shit you not, I grow verticaly and with 3K and I can't see the walls, and most of my plants are touching the ceiling. Things happen FAST in the buckets and if you follow tokes directions when you construct them, they work beautifully. Again, never had to do a res change out, and never had to do a PH adjustment, except for the start-up adjustment. I started with 12 buckets , 12 clones, I lost one clone and didnt replace it, glad I didn't cause you can't even see the missing bucket for the jungle. So, 11 plants completely fill the room, and obviously next time I will switch them over sooner.The main stems are over an inch thick on these bitches. unbelievable.Thanks for the advice guys. Okay so I'll go with the larger size lava rocks (at least 1 inch) and thanks for the tip about keeping the stems out of the water.
The more I know going into this the fewer problems I should encounter down the road.
I'm still waiting on seeds but I want to start gathering materials ahead of time.
Another question if you don't mind.
I read somewhere that growing out more than one strain at a time doesn't work so well.
Something about growing in the same medium causing the taste and high to be pretty much the same no matter the variety of seed.
Any truth in that?
Yeah you do not want to submerge the stem. Now because I vegged in a separate section i could submerge mine a little further and make the stem level with the water line but I already had a decent root structure going.
