Thanks all, and especially for the picture note. Hopefully they stay healthy for the next couple months and reward with some satisfying pictures and meds. There is a similar 3' x 3' space running 400w of HPS with the same cuts that will be making an appearance for a bit of a comparison
I did get a 2' x 2' tent from Mars alongside the SP-150. While small, it should be quite useful as a pollen tent for males.
Here's a reversed OG Chem and SUSQ Chem hanging out in the Mars Hydro 2' x 2' tent. Plants were reversed with homemade colloidal silver. I generally produce it as needed and make a quart of CS solution every two days. Spraying approximately 1-2 weeks before flip and daily until 21-28 days as male flowers start to open up.
There's low level lighting and minimal ventilation while they start to drop pollen over the next several weeks in their mars hydro tent isolation chamber.
The tent is well sealed. I've got pinholes all over a different tent from amazon, and through the zippers. The Mars hydro tent seems to have better light proofing without the same light-leak issues as of yet. It came with a few extra straps and attachments that are useful. The zippers could use a little oil, but a little harder to use is likely due to the additional lightproofing materials around the zippers which is preferred. All said, it seems like a great tent and will work well for male pollen collection.
