Into second run using Mammoth P but first time attempting a reasonably credible side-by-side test.
Headed into week 5, Larry OG from same clone, x4 plants per table, one table running Mammoth P and the other not.
Setup:
>> All under Gavita 750's at 825w on 12/12 schedule
>> Growing in coco/perlite 50:50 mix
>> 8 week veg, flowering in 3gal pots
>> Sealed room w/CO2, 80-83F + RH50% (RH60% at canopy); night time 70F
>> Root zone temps 72-76F
>> drip drain to waste fed 5 x 1 min per day, total around 1gal per plant per day
>> dry salt fertilizer program maxed at 1.8EC + pH always at 5.8
>> only other bios used are Hydroguard, Recharge (and BioAg Vam mix at transplant only)
Table 1 no Mammoth P
Table 2 running Mammoth P, included in twice weekly Recharge "tea", not in fertigation.
No discernible difference in quality of canopy. Both tables healthy and perky.
Flowers set on table 2 much earlier than table 1, with bud sites established by week 2. More than half the cola tops on table 2 are looking fuller at the same development stage.
Canopy is thick and green and waxy leaves on both tables, but table 2 showing some interveinal deficiency on youngest leaves. Unlikely Mg as plenty added so may be iron.
TBH I only noticed this once editing pics to clean up the yucky HPS light color temps; hadn't noticed with lights on.
I've been told iron can be imbalanced at the root zone if fertigation rates are too high, so I might have to look at my 5x1min drip schedule.
The most noticeable difference in the tables being the branch thickness and growth vigor of table 2. I've never had such robust and sturdy branches and they are evidently thicker/stronger than on table 1.
Some on table 2 were becoming difficult to train beneath the scrog by week 3 due to rigidity and really push up on my screens.
The main stems are also thick and trunk-like, with very sturdy and woody roots bursting out the medium. The above stems are about 1inch diameter, with the top of the root ball more like 3.5" inches in circumference.
Quality and strength of branches seem to be the biggest added value when using the Mammoth P. Flowers also set much quicker and seem further along in swelling than without Mammoth P; with impressive weight put on even for week 4.
First run with Mammoth P I just went at it and very learned quickly I was overfeeding them and got some pretty spectacular foxtailing. Consequently I rolled back my feed EC to 1.8 (previously 2.1-2.2).
I kept it at 1.8EC for the sake of this little test.
It seems like with Mammoth P you need to feed lighter or will run into problems. Fox-tailing I presume from excessive P made available by this stimulant with all other variables seemingly equal.
That first run also yielded 2lb/per for the first time ever, which prompted me to do this little study. Was it due to Mammoth P? Will need to see out this test run before I decide.

Price is bonkers but i've been stretching this free sample pretty far by including it in the twice weekly brew of Recharge instead of putting 1-2ml per gal in the reservoirs.
Using it this way may have restrained the potential of Mammoth P, but due to cost I can't see myself including it as a regular additive at full strength.
If you're running teas and looking for a little extra bump, or maybe you just love the latest & greatest in a groovy bottle then check out Mammoth P. It might be worth every one of your pretty pennies.
