Need help with buying proper equipment I’m on day 11

March 28 2020 I germination 12 seed 10 made it though the soil I had them in a sun blaster nano dome with two 2ft 65w led’s I put my baby’s in my 5x5x7 tent yesterday
I monitored the temperatures the were way to cold 15.5c
Under a 1200w AGLEX led so I bought a used 1000hps setup the hood is a wing style hoping I come get some feed back in what is the best 6ich air cool hood for a 1000hps/MH
I found if I run the led 18/6 and the hps 3 times a day for 3 hours the temp are 23.5max and in the night the low’s were 17.8max
I have some seedling nutrients but I don’t know when is a good time to start them I have been PH the water to 5.7 to 6.1 with blue lab pen please help me out thanks !!!!!

I also have sun system 150hps should I be running that

I run 2- 1000w hps + a 600w hps in my flower tent in these.
Couldn't be happier. Quality and price are great.
Link to my journal in my signature of you want to have a look.

The 1000w should be enough.

I'd be watering them less as they look saturated IMO,

I run my room at 25 to 27 c in the light cycle and I dont like to let it get below 23 at dark cycle so if I were you I'd let it get warmer all around. If you are running pure soil the PH should be around 6.5-7.
Be careful about to much light intensity during the plants infancy.
