Hi folks,
Thought I would reach out to all of you experts for some advice; I am using this new ebb and flow botanicare tray and reservoir and have been trying to figure out the best growing materials. I need some help!
Right now I am using grodan slabs, scored to hold 2X2 rockwool cubes. Thought this was a fabulous idea. Notsomuch. The slabs seem to get algae because of excessive water-holding. I really dislike them and am getting to hate rockwool in general.
You can see residual "green" on the bottom of the tray if you look closely at the pic.
I know from past experience that hydroton sheds water much more quickly. I hate working with hydroton, though since I work full-time, have a small child, and it is so darned messy (plus stains everything clay-colored pretty much forever). My last few grows have been hydroton and I tried to avoid it this time.
Anyone have any advice about the best grow mediums and setups? I've thought about using those mats. How do they work? With rockwool? Any and all advice welcome. Below is a picture.
Oh, and if anyone wants to answer a second question: If you were me and wanted to correct it this grow, how would you do it? I have a few stunted clones because of these crazy slabs.
