Well, I 'll give you a little tease on my AF20 as of 2 hours ago:
......the smellyest shyte I've ever............ G-13's WW at 50 days and comes down tomorrow. Looks like I 'll get my 2 lbs cured out, but I was really hoping to do better this time and ended up frying them with heat and ppm's, way high pH a couple of times as well as up to 1500ppm(I never go over a 1000ppm in this AF)-----but they had a rough run, that is for sure and look to be about 75% of what thay have been in the past runs....but they still will be at or over 2 zips ea.
So yeah, you'll be shocked when you get that up and running/dialed in.....and if it goes good for you out of the gate, you'll never look back. Get yourself one of those 27 gal black totes with the yellow top and make a real res for that thing(the stock one they have is way too small and to keep your ppm's in check you want more water---they will end up useing a couple of gallons a day and your ppm can go from 700 to 1500 in nothing flat with the 7 gallon res) Also if you get some time do a pvc frame(let me know if you need any ideas for that). But remember, it's all in the GH spray lines + the NFT depth <-----the combinations of those...... YOU CAN NOT DIY THAT------remember that 35 siter diy I have? No comparison.....
Haha, sorry, bro.....ramble ramble......but your the one that brought up the AF
Hope all is going good!!
