Anyone else have trouble with critical magic, I’ve gone through second pack, and all duds, I know I’m not doing anything wrong, because I started Chemdog, and Runtz at same time and they came up like champions.
I wish I knew if anyone else having trouble with these seeds, when I bought them a year back all came up crazy good, .
And it worked so great for pain and sleep.
I asked them if they could replace the seeds and they did, best service hands down..
So I will not ask for anymore of this type and definitely will not ask to replace again..
I’ll stick with what works for me, but honestly what is going on with these seeds, they don’t even look right, they are small and white, as if not formed enough for a true seed, meaning had they allowed the seeds little more time it might have worked, .
Sure I’m upset, but I’ve never been so happy to be with this amazing company, thank you to all the staff, things happen..
We just got to keep going. And never give up…

Holy smokes, I don’t even know where to begin, I mean I’ve said thank you so many times to your amazing staff, is there anything better than thank you..because if there was I’d say it…
Please know how thankful I am,
I grew 2 at first, they were some of the best flower for pain ever.
I went to start the last 3 a year or so later and I guess I screwed up again,
You know what I dislike, people saying it’s your fault, no it’s his fault no it’s there fault..listen shit happens at the best of times, so don’t use the blame game growers, look in the mirror.
To end I thank you so very much..can’t wait to start these, but started to germinate Quebec black, yippee…life is good.
My master used to say, “ Pain is joy, and joy is knowledge “…
Didn’t like this saying at first, until I truly understood.

Wow, and I thought I made a mistake buying these seeds, and boy, it’s the strongest pot I ever grew, so strong I can’t even take a few puffs, and put it out, beautiful plant, can’t wait to grow my other 3 I have left…I’ll start those after my fruity pebbles are finished, free seeds, they gave me two free fruity pebbles seeds, and so far at day 7 of flower, it’s also going to be a winner…she is so beautiful…I’m beside myself…happy as can be.

My second go with Critical Magic. The outdoor grow in my hot climate had one dead seed and the four other plants died. This time indoor SOG. One seed was dead the other four grew into exceptional plants with one having mutant genetics- grew weird right from the start. So the good is excellent but the down side left me short handed. There is risk.

Harvesting my Critical Mass today very happy with the results. Nice size, tastes great and it does the job with flying colours (I trimmed a few buds in advance of harvest). Happy enough to order the critical magic, I received them today along with others but also received some bonus seeds. Thank you QCS.

Follow up. First this is a great company with a top notch team. I have to report to growers in central CA. I was excited to grow Critical Magic and waited a long time for it to come back in stock. I mostly prefer outdoors and that’s what I’m talking about here. I planted 5 Critical Magic outdoors. One never came up. No big. This company is very solid and made it right. Had a little heat wave here in July. 105-110 F for a week. Two CM plants died. Two were just fine. Then at the beginning of September we had another hot week with one freak day of 115 F. That took out the two that had survived. And now there are none. For me it is a strain for indoors only. The big surprise was the M39. Toughest steam out of all of them. Left me very surprised. Best small area strain out there. I should stick to Sour Diesel, Critical and Mexican/African strains in my area. Tip of the hat to my fellow growers in Canada.

I had been monitoring Critical Magic for a year hoping it would. Everything about the plant made me want to grow it. It finally came back in stock and I had to get some. I am limited to the number of plants I can grow in the California city I live in. I grew 5 of these, 3-M39, 2-NL X Skunk and 2-Oaxacan Highland Gold I got elsewhere. All in the same spot and in the same soil. All seeds broke the surface on day 3 after planting. All but 4 of the Critical Magic. I waited until the end of day 5. Then I started digging. I found all four seeds. 3 were attached by root and one was dead. The 3 live plants all came up. They just took twice as long as the other seeds to do it, I replaced the dead seed with a Super Skunk seed this awesome company sent me. It came up in 3 days also.
