Week 5. Jack is growing solidly and the new tops have stretched out well. Looks lovely and healthy after the rain showers last night. So good to hear,, I donβt think is has rained here in the 5 weeks jack has been alive! I have spotted a few hairs already which is definitely earlier than I was hoping for. Was hoping to top once more and get another week or two in veg before putting the cover on to finish out. I suppose it is what it is. Will keep an eye on it for a few days before deciding whether to top once more. I did expect this, but last year they made it a little further before turning. Either way Iβm happy with the way the jack is kicking along. π»
@Shooey, Same here mate, few 30 plussers with glorious sunshine in a row and things just shift in another gear π²
This weeks updates are gonna be fun πβοΈ
I think you leave cup at certain hours and unfurl at other. And I don't think that it is too serious. Could be from varying humidity during the day. A way to check is to plug in numbers for VPD.
In case you don't have it, this is the formula to indicate how fast water would evaporate :
VPD = 610.78 x e^(T / (T +238.3)) x 17.2694 x (1 β RH/100)/1000
The folk lore says for vegging VPD should be 0.8β1.1 (kPa)
And for flowering VPD should be 1.0β1.5
Lower VPD means its wet. Water less. If anything, get a fan or spay anti-mold.
Higher VPD means its parch. Better water more often.
I put this in an excel file. Realistically I can't do much to effect outdoor rain. Best thing to do for me is to grow in season like normal people would.
@Med_in_Tropic, geez med, Iβm flat out putting my pants on the right way, let alone work out that formula!! Iβm gonna need a few smokes beforehand for sure ππ
I donβt think itβs humidity as itβs been really mild so far this year, but you might be right about watering. Not sure if I am getting it spot on with jack. Still, itβs another cool looking thing that I havenβt seen before. smells great thoughππ
@Grey_Wolf,hi mate. I can but i wasnt planning on it. I planted early sept last year and they flowered out. I figure at 5 weeks we will just be over 12 hours light here and they should finish out. Your thoughts mate? Do i risk them going back into veg or hermie if i dont cover them up?? Cheers bro
