First grow ever, GMO auto Barney’s farm

I would use a little grow box for seedling and put it inside ur tent. It will hold 70%+ rh all the time. Otherwise you use a humidifier!! But don’t use ur carbon filter if you use tap water! You need RO water without any calcium magnesium in the water. Because the carbon filter will stop working it will get full of white powder trust me I’ve done it before! It’s the best way! Then you need a hygrostat! You just plug the humidifier in it and choose the wanted RH% and it does the work for you! Or you buy a humidifier from spider farm or mars hydro they have good ones but expensive then u don’t need a hygrostat. So you need equipment to keep the right conditions you wont be able to control it without. Trust me it’s very hard to keep the rh down where I live it’s very humid!

This will differentiate greatly by strains. It looks like the majority of the diaries here growing this strain have seen the end of the vegetative cycle coming at weeks 3-4. So you are right on track. If you are noticing a massive growth increase you are now entering flower. I would bet you will start seeing pistols forming in the coming week. My last Auto run all had four weeks of veg before they started flowering. Like you mentioned, it was an explosion of growth once they entered into flower. Time to give it a bit more light and switch to bloom fertilizer. It also looks like the majority of diaries here growing this strain went 10 total weeks so you are nearly halfway to the finish line my friend. I hope this helps.
