White Widow Grow- Generic Potting Soil vs. Miricle Grow

High Folks.

Those of you who know me know that I am against Miricle Grow Soil with time release ferts because my first two grows were ruined by that and similar soils [see PGAMG in my sig]. Many people argue and say that inexperienced growers screw up their own grows and MG is just an innocent bystander.

Well, I now have almost five years of indoor soil growing experience so, I figure I should give it another try to prove what I already know.

I will be starting off with four White Widow seeds from Gypsy Nirvana. There will be three in my generic potting soil that I have used ever since the initial disasters and one of the beloved $10 seeds will be wasted ahem used in the name of science, in MG vegetable and flower soil that "feeds up to three months".

First thing I noticed was how clumpy and heavy the MG Soil is compared to the other soil. This is why drainage is often a problem and I have opted to NOT use additional perlite because a lot of peeps starting off don't know or want to use it.

Secondly, by doing a run-off test from the initial watering prior to putting in the seed, I noticed that the three pots with generic soil gave a run-off pH between 6.5-6.8. That was with nothing added to my tap water which by the way is at about 7.15 pH. The MG pot however was giving me a reading of 7.2. This was strange and counter-intuitive to me because chemical nutes should lower the pH not raise it; at least in theory.

So right off the bat, before I even put the seed in, I had to add the pH downer to get it to 6.5. It actually took me a few pitchers of water to lower it because the shit would just not lower. So, it basically accomplished a flush before I even got the seed in which was admittedly frustrating because it would just not lower. The last pitcher of water I gave it was pH at about 6.0.

Third thing was I only saw a few tiny little fert balls so picking them out in an attempt to stop over fertilizing I think would be a waste. The soil itself must have fertilizer as well.

Other stats:
8" pots to start followed by three gallon pots to finish.
400 watt MH for veg 400 watt Hortilux HPS for flower
About one month for veg 18/6 [no 24/7 to start because using MH instead of CFL]
Topping/tipping
Fox Farm three pack [organic] for food
One female will be dedicated as a cloning mother

As we all know WW is probably the most sensitive strain to fertilizer so if this soil works on these it will work for anything. As a footnote, I had a few WW's that got hungry at week two of life so I fed them then and they were fine. This is also early for feeding and I never have needed to feed that early. Maybe it was the MH light I used for the first time?

Anyway, I won't feed the one in MG until it needs it which will probably between mid flowering to never.

Stay tuned for pictures and I will put them in the soil after clicking this reply button.
