Samuel:
For most plants, I bareroot them prior to re-potting in Tapla's soil mix. For these four mangos, I didn't fully bareroot them as I was worried they were too stressed from the week and a half it took for me to get them - I removed some of the soil but not all.
My CFL's on one side of the room are a 26 & 60W and on the other side are a 26 & 13W.
I only started heating the room up to 24C in January '12. Before that the house temp would be ~18C in the mornings (6:00a to 3:00p) and at night when I go to sleep but still no flowering on my mangos.
I think some of the people (including nurseries) don't like shipping direct to Canada because they get held up at customs who may want a CFIA inspector to review the package, etc. and the survival rate decreases dramatically. That's why I have been having them sent to Niagara Falls and then driving over to pick them up. Before the last problem, it would be about five days at most for me to have them.
This time the cost per plant was a lot ~$85 after the cost ($30 each x 4), shipping ($75 so ~$20 each) & the phyto, also $75 & then with the travel insurance, tolls, gas, exchange, etc. for two trips, it came up to ~$85. When I bought my Mallika from Flora Exotica last year, the cost was about $90 with shipping so not much of a saving when the phyto is calculated in along with have to make two trips.
