You could use some hydrogen peroxide to kill the algae. I hear works pretty well.
Thanks for the advice! I actually read around the forums, and did just that after work today.
Day 8:
Well, I took off the foil today. I hope 24 hours of darkness was at least semi-effective. I just couldn't stand having all this foil around the girls, so I took it off!
I mixed a weak hydrogen peroxide solution in preparation to water Hazel (the bigger one), but upon further inspection, I don't really think she needs watering yet.
Five days ago I thoroughly watered that 5 gallon pot, and I'm pretty sure there's a good amount of water left - Hazel sure as hell isn't drinking it all, and I don't think that much is evaporating. So - I'll wait on the watering.
I did, however, spray a slightly higher concentrated H2O2 (peroxide) solution on the top of the soil, to hopefully finish the algae off. I'll keep a watchful eye on it.
Eve is still going slow... She is getting larger though! Maybe the transplant hurt her somehow and she's all confused, haha... Anyways, since I've got limited space, and I am ideally vegging these until the last week of May (assuming they don't get TOO big), I may do a circular LST on Eve. If it works, great, and if not, oh well, I was limited on space anyways. What do you guys think?
I was initially worried that Hazel's fan leaves were drooping a tiny bit (hence the side shot), so I took a picture of it. My other hypothesis is that, since there was foil right below, she was getting light from below too, and didn't feel the need to stand quite at "attention", haha...
