McKennaii Cloud920® Classic XL

Product Review (submitted on March 27, 2026):

1st flush - Fresh air exchange started 3 days after set up. Pins started to appear at day 8 at both the top and all sides of the cake. The mature fruits were harvested between days 14 and 25. Most of the pins grew at the sides of the cake and got squashed. The harvest was cracker dry at day 27 using the fan / silica drying method. The 1st flush cracker dry yield was 20.7g. I was pleased with this yield. I used a heat mat with the thermostat held constant at 21C that promoted a very light humidity.

2nd flush – After harvesting the 1st flush, I misted the top of the cake with x25 misting sprays to rehydrate it. I used the same approach as the 1st flush i.e. heat mat, fresh air exchange started 3 days after misting and very light humidity. Pins started to appear at day 5. At day 10 I noticed most of the pins were growing at the side of the cake and getting cramped (like the 1st flush), so I carefully removed the cake from the container base and replaced it on the container lid to allow more space for the side pins to grow. The mature fruits were harvested at day 12. The harvest was cracker dry at day 15. The 2nd flush cracker dry yield was 5.3g. I was pleased with this yield but did expect a little bit more.

3rd flush – I am 3 days into my 3rd flush, and it appears that pins are already starting to form. Before starting the 3rd flush, I soaked the cake for 8 hours. I am using the container lid instead of the container base to avoid limiting the growth of any side pins.


MMS: Great to hear that this method of removing the substrate from the plastic box worked well for you! While this can sometimes help side pins develop better, it is not recommended in every situation. If you ever experience issues or are unsure which method is best for your kit, feel free to contact our customer support so we can find the most suitable solution for your specific case.
