Hi,
I'm a forum newbie with some questions about tomatoes ripening to red. I'm in the front range of the Colorado Rockies at over 8,000'. Because of hail, harsh winds, extremely strong sun and short growing season, I decided to experiment with growing in my garage under T-5 lights (4 tube, 4' fixtures).
They are on timers to receive 14 hours a day of light. I started with 6,500 K lights and switched to 2,700 lights to encourage flowering. I have 3 varieties I'm trying, San Marzanos, Goldman Italian American and Principe Borghese.
The PB has progressed the best and has the highest quantity of fruit. The others are progressing but, at a much slower pace. The PB's fruit has been there over 60 days and none have turned red. Temps are usually between 75-60. Any suggestions to try to help the reddening process, defoliating, perhaps? I have removed some suckers but, I'd like some input before I start snipping.
Thanks!
