I have a Wappa that I got as a freebie along with a Belladona and a couple Delahaze they are next up to be popped (trying to work down my backstocks before ordering anymore lol) I'll be interested to see the responses.
Wappa yields very well,mine was 7-8 weeks,hard nugs,great bag appeal...the high is rather bland for me though...reminds me of big bud,nice look,nice smell,nice taste..alright high...i have pics if you want
I've not grown either, but I've smoked both. I agree with Flash about Wappa. Although I'd say bag appeal just above average on the sample I had. High boring and bland and quick tolerance build up.
Delahaze is more fun to smoke, but there are plenty of better Haze hybrids out there. JMO based on dispensary samples.
Chronic is supposed to be a heavy yielder of decent quality. Never tried though.
