okay so you think i should just jump to the 6" version right away instead of the 4". Whats the downside if i overdo it? like if i needed a 4" duct instead of a 6"?

What do you think ? Go to the 6â. Iâm pretty sure it the tent I have can accommodate 4 or 6â ductsâŚ

I would go with the 6" if you havnt purchased yet. Like you said, a little more airflow wont hurt. I think some even have different speeds.

I will say my 4" fan clears my 12x8 grow space well enough that people right outside the roomâs entrance canât tell I grow. In my opinion it is better to have a higher quality carbon filter.

okay so I just feed them, 1/26, last feeding was 1/20 (drench to drought) afghan got 96 oz of RO with jacks 321 at 6.5 PH, 650 ppm (48 oz) , and 6.7 PH 450 ppm (48oz) run off was 411 ppm and 7.3 PH ( a little high i think) what you think @OGIncognito and whatâs the process moving forward. maybe just 6.4 ph RO with whatever ppm next feeding?
GDP auto is doing better i believe. I havenât tied her down yet or anything like that, but i believe shes sprouting, anyways. feeding on 1/26 goes as follows⌠I adjusted by the way bc i fed the afghan first and read numbers adn adjusted accordingly. numbers were feeding 6.3 PH 550 PPM (48 oz) and 6.6 PH and 346ppm (48oz) run off was ppm 408 ph 6.7
next feeding im thinking more ppm per 48 oz jar and and lower ph for afghan auto like 6.4 maybe? @OGIncognito i think i will keep the same feeding maybe 600 ppm and 6.3-6.5 PH for GDP auto.

by the way i used 12 grams part a 8 grams part b and 4 grams epsom salt in 48 oz then split it up and redistributed RO into mix to make two jars of 48 oz. i guess i could just get a bigger container to feed them? foruming out loud here. lol

Grow is looking good so far. Welcome to the adventure! 
Was wondering if you wouldnât mind clarifying for me - what do you mean by a âdrenchâ? Is this simply your way of saying that you are watering them!?

Feeding or watering to liberal run off, then let it go through a dry cycle and repeat the drench. Soil likes a drench to drought routine
