1) after how long do you reckon it will start showing hairs?
2)any tips would be much appreciated
3)and what do you reckon my yield could be?
1) impossible for me to tell. no strain info, no atmosphere, feeding, substrate, air flow, temps....its a guess, better if you guess it not me.
2) read words, ignore forums

3) It
could be about a pound of course. But when you get mold because your humidity is whacked yield will diminish.
when you let your grower buddy in to spread some mites....you might lose the whole crop. When you dont follow directions on your feeding chart you will lock these up, whack the ph, and stop development. While you're overwatering thinking to make it grow faster your substrate will suffocate and kill beneficial organisms and fungus, rotting your roots, diminishing yields also. When you see your first issue you'll no doubt choose to follow the advice of many here, like add cal mag, or start training, or spray something, or use a bud stacker or add some PK or change your light schedule to 14 hours of darkness....and they may fail. If you vegged for 5 months and provided every needed seriously though, you could potentially yield 8 ounces per plant, but c'mon now....be real. you cannot supply its needs correctly for that long right? Without proper controls failures result.
so you see, its a fantasy asking others how many apples you think will be on this tree when it grows up,(..... if its fed right, if the sun shines all day, if nobody breaks it, if mold doesnt get it, if bugs dont get it, if you dont tip it over, if you dont poison it.........)
