Temperature Question for Deep Purple Strain

I germinated 3 DP seeds a couple weeks back and they are doing great. I have a few questions, i brought the temps down to around 74 degrees with the lights on and around 69-70 degrees with lights off. They respond much better with those temps than the previous 83 degrees i had it at. My question is are my temps to low or should i keep them around the low seventies. Also, its been about a week an a half and its about three quarters of the size as other plants im used to. Is this normal for DP to grow kinda slow like this?

read the strain guide its pretty clear


Purple Urkle X Querkle

This strain was created to lock down more of the Urkle dominant traits and bring out more of the musty grape taste that Urk is famous for.
The strain produces a wide range of female plants and not all of them will exhibit colors at all. The ones that due however are highly sought after and several people concider there Purple Grape females amoung there best Indicas strains. Not a huge producer or a fast growing plant it makes up for it in taste and high quality.

1) Phenotypes- Look for the short Indica Dom females with Purple tinge
2) Height- Short and stocky slow to grow upwards
3) Yield- Medium
4) Indoor/ Outdoor
5) Best Way to Grow- Long veg and remove some shade leaves to allow light under
6) Harvest Window-50-60 days
7) Sativa/ Indica 20/80
Purple Urkle X Purple Querkle Male
9)High type- Calming and relaxing and very fun to smoke
10) Taste like Grape snocones
11) IT was named after the Band not because of the coloring

ah thanks sub, whats an ideal temp?

I have grown this strain and she is a slow veg grower for sure.As for temps 74 to 78 for day time is pretty much I deal.

thanks ocanabis
