Gorilla Cookies Autoflower - Sonoma Seeds - First Grow - MICROGROW

Germination:
After 17 hours in the pH balanced spring water, transfered to a wet paper towel for 48 hours, keeping the paper towel wet and temp at 75-85F. 2 of the 3 sprouted within the 48 hours with just over 1/4 in taproot, the 3rd took 24 hours more. Seeds transfered to 3gal pots with 65% Promix BX and 35% Perlite. I seem to have to water the media around the seed every 8 hours or so, drying very quick but I am also trying not to drown the seeds. This is my first grow, please let me know if you guys have any suggestions, any and all help is appreciated and encouraged! Will be using the FloraTrio and CalMag along with LST and Maybe topping, I heard topping autos is controvertial, what do you guys think? BTW 3 wet tea towels in the grow box took 40% humidity to 85% when changed 1-2 times per day and a small space heater set at 24C.

Is it normal to have the media dry out in just a few hours (65% Promix BX and 35% Perlite)?
Keep in mind im not soaking the whole pots, just in the 5-6 in circumference around the seeds.

Watering using pH balanced spring water.

First off the top is only drying out. The trick is (unfortunately a little late for you) is to moisten the media prior to planting the seed. Especially in fabric bags. By the time the plants big enough to give enough water it dries out around the edges.

Now that ship has sailed the thing to do is wait until they break the surface then remove those domes. Spray the soil 1-2 times a day to keep the top moist. Water 250ml every 3-4 days 2-3 inches away from the base of the plant in a circle. Roughly every week double the volume of water. Around week 2 you’ll need to soak the edges of the fabric pot (will be bone dry). Just simple place 500ml of water in the saucer and let them drink it up!

Nice good luck mate
