I am a new member with a few questions. I recently purchased 4 mini rose plants from on online dealer. I have them in a 4 plant top feed drip hydroponics system with a 400W MH light. I did not repot the plants yet because I want to give them time to adjust to their new environment. However, I am unsure if I am over feeding them being that they shipped in a peat medium and I assume it comes with nutrients already. Currently I am watering them once a day for 15min with approximately 600PPM of Tri Flex 3 part Base, Grow, Bloom formula. I’ve never grown roses before and would appreciate the advice. I also have concerns with the temperature in with they are growing in. My grow room is between 80-90 degrees and I believe I read that roses like cool weather in the 70’s.
amIover feeding? If so what are the signs roses provide?
2.Is my temp OK? If not what should it be?
3. Anyone grow roses in a hydroponics system? What were the results?

Thanks…

Cheers!
