Creepall You can use simple tap water for a week ;) Then switch to your veg nutrients and follow what they say on the bottle (honestly I wouldn't go over 70% of any nutrient's dosage btw) For humidity you should check out VPD, but if you want easy made up numbers, 65% for early veg, 40% for late flower, lower it down slowly during the whole process

Creepall You are going to need a humidifier, and when watering, well first let them set in, so small amounts every other day, but in the end, drench these suckers they love it. I use a 25L (7gal) pot and water 8L once a week, it works for me... I felt the exact same way at first don't worry lmfao it'll be fine you will start to see yourself when they need water they'll tell you. Also you could take that net down and let them grow for a small month before flattening them out with the scrog, you have time ;)

Creepall And if you want to go overboard I can tell you how to craft a cheap co2 generator with sugar yeast and water ;) It works great blblblbl 🫧
