Well done but it needs more work
- Tin foil, ditch this stuff and use any of the cheap alternatives to mylar or just buy a cheap ass three meter length of mylar. We never use tin foil its bad practice and reflects not diffuses.
- You need a few more cfls say four or better still buy those cheap ass flouro strips from a grow shop for a few bucks.
- I see one fan, it ahould be sucking the air out not blowing in and wont need to be set very high, i use a cheap voltage transformer and there are threads on how to connect so you can adjust fan speed.
- Find a more shaded place for thermometer and hygrometer, light radiation will affect it and not what we want, i bet your bix is a touch cooler than actual readings.
If any of this seems exspensive or a hassle you picked the wrong hobby, pre made plug and play veg tents are sold everywhere if you hate diy.
- Dont make fire check wiring and circuits
