Well, guys, it's a new day, and time for some new fun. Well, new day in for me at least. Still on the same DAY 79 in the grow though. I have so many damn pictures (about 150 just for DAY 79 ) that it takes me a long time to post them all!

But first, GK & Invision had mentioned the rockwool oddity part of my grow, which I really dont find that odd, but I guess it is not the must orthodox way to do a grow. There are of course positives and negatives to growing soley in a rockwool substrate.

Positives:

Easy to move/adjust plants.

Rockwool holds almost the perfect amount of water. It is difficult to overwater them. I read somewhere that said they hold 18% air at all times. I dont know if this is true, but I "dont think" I've had any overwatering problems. They are easy to check to see if they are moist: light = dry & heavy/squishy = wet!

Very clean. No messing with overflowing NFT/DWC systems or messy soil. Now I'm not bunking soil in the least. I would love to do a soil grow and use organics, but for practical reasons, rockwool is better (cleaner).

Negatives:

It is not soil. It is made from pulverized and spun fibers of...ROCK. Mainly basalt. Someone likened it to making cotton candy out of rock.

Rock has a higher pH than some, therefore I have to adjust the pH of the water lower than I would usually to account for the increase in pH in the runoff.

Susceptible to mold. If you look in some of my pictures, I have mold growing on almost every one of my rockwool cubes. I was first noticing white salt build ups (which might be another negative) but then came the brown mold. Ewww. I assume this will appear anywhere you have high humidity, light and air. One must cover one's rockwool - imperative.

^^^However, the mold has not seemed to affect the plants' growth. Odd.

So this is my take on rockwool. I'm sure it's not fully comprehensive, but it is what I could think of off the top of my head.

(looong pause)

I started this damn post like 3 or 4 hours ago. I've been SO busy!!! I'm just gonna post it now so I dont lose it. And cuz I've lost my train of thought.

Little stressed...would love some destresser medicine. :rasta:
