Here is my opinion on TGA strains: My opinion btw is based on what I have so far smoked and grown of TGA genetics. I only recently stumbled upon the whole scene of TGA but in that time I have done a crapload of reading about them, searching for reliable samples to test them, and obtaining a 10 pack of Vortex to grow out....
I freaking love them. Seriously. To cut to the chase It seems that because, as the 1st person to respond to your question mentioned, the strains are hybrids and they have some variation. However, the "keeper" pheno(s) that are found in the strains I have had (I have not had every strain in their menu right now...) are amazing. And not only that....they are EXTREMELY close to the description that Subcool provides. I honestly did a month or so of reading on strains like Jillybean and Spacebomb before locating reputable sources of nice finished flowers.....and upon smoking I was greeted with an intense flavor that I was expecting (Orange candy for the Jilly and super-sour rotting fruit on the Spacebomb..) The highs are also very well descibed. I have had some very happy experiences on Jillybean and JTR kills my backpain does great at killing pain. My experience so far at growing Vortex is (they are in week 4 of flowering..) that I had all 5 seeds I started germinate. I had 4 females out of the 5 plants. Yes all 4 females are different, but 3 of the four look phenomenal at this point. I have never seen resin-production at week 4 like this before. I had been growing Chem#4 before and I thought it had a lot of resin early on. Nothing campared to the Vortex right now! The smell from two of the females is, again, exactly as described with a crazy mango/lemonade smell, and the other 2 smell amazing as well (just more pepper in one and lemon in the other..) Time will tell how it will cure up, but I am very excited. Anyway...sorry for the long response but to be honest I get suprised by opinions like the 1st person, but to each his own and we all have different preferences. For me though; I feel like TGA strains are realiable for me so far in potency and flavor. Have a good day!
