The top soil of my plants pots get dry under my 250 watt mh. I try to keep the soil moist using a mister. Will i have and problems? If so any advice would be welcome! Thank You!

Get some clingwrap and cover the top of the pot with it, leaving like a 1/4 inch gap between the stem and wrap. Then place something fairly light proof (thats not black cause of heat) over that, will help keep humidity up and temperature down, making the top stay a little moister longer.

When do you water?KEEP SMOKE ALIVE!!

Varies from plant to plant, temperature, humidity, airflow, ect.

Mine are in a very hot place, usually 90-95 degrees, I water every day. But basically if the soil is pulling away from the pot, as in theres a gap between the soil and container, you really need to water.

Basically, just slowly pour water in the container, giving the soil plenty time to absorb it till the point it flows out of the drainage holes. Figure out how much water that is. If your plants need watered every 3-4 days, I'd water like 1/4 the drainage amount each day, and on the final day do 1/2 to full drainage amount. Repeat. Takes abit of scheduling cause each plant has different water requirements.

Perfect.KEEP SMOKE ALIVE!!

If your temperatures are like 75-85, only do it every other day, to give roots time to air out. Everyday just works for me cause the insane heat my plants have to deal with.

Yea it's hella hot out here in CA! KEEP SMOKE ALIVE!!

Thank you for all the help. I try to wter every other day and mist when needed. Temp is around 80 or so.
