Heat Question

I just started my own grow room using led lights in my basement, the thing with leds are that they dont heat very much, the temperature down there is
59 F and i am wondering if a heatsource such as a space heater will suffice as a grow room heatsource.

Here are some pictures of my room




i know it doesnt look like theres any weed in there, the sprouts are just started, or finishing germination. i have them on marble tiles and a tarp that drains to my spetic tank cause the floor is angled. The floor gets pretty cold, but i have the plants in the small greenhouse and two outside of it in the other empty looking pots.

These are the nutrients im using right now


If anyone has experience with the dutch nutriend formula hydro grow for early growth, please share the frequency in which the nutrients are used. because the bottle doesnt say and the mircle grow is liek aone time use and the rhizotonic is 1-6 tiems a day and the hydro grow says nothing. I appreciate all the help

Yes you need more heat

When you put in the heater make sure it doesn't blow dirrectly on plants it will dry them out. You do need heat for sure. Look into reptile heat pad it may be better if your in small area. Good luck.
