First Time Indoor Grow - Any advice? I’m a Sponge

Howzit ouens, Southern Hemisphere grower here, about 5/6 days into my grow and my seedlings seem to be doing alright. (Germinated 6 days ago

My Set Up:

2x Auto Gorrilla Cookies


- 0.9m x 1.2m x 1.8m Tent
- 600W Duel Spectrum HPS Light
- Air Cooled Hood Reflector
- TD-250/100 Silent Exhaust fan
(Pulling from hood, exhausting out the tent. Ducting connecting the other side of the hood brings in cool air from outside the tent.)
- 15 cm circulation fan
- 600W / 400W / 250W Digital Dim’ Ballast
- rDWC mini Bubbleponic Res (Images attached)
- Dophin 5500 air pump




These are what my average temps are looking like: (Max [day]



Water Temps are are ranging between 21-23 C, with my light about 110cm from the seedlings right now, dimmed down to 250W.

Any advice would be appreciated

Post spazzed out a bit, also 2x Alien Kush Autos

Goeie aand dagga lovers, this is what the grows looking like so far (using this as a bit of a grow journal)



Been germinating since 18 June, popped out of the rock wool 22-23 June. So the seedlings are 4 days old?

Temps are sometimes jumping to 27-29 C, is this causing heat shock maybe? I was hoping for faster growth. It dipped to about 17-18 C over night, with the water temps staying around 22 C. Still no nutes. I’m considering getting a stronger air pump or even a second one. The bubble distribution from the airstone is only about a 10 cm radius visibly. Not sure how much O2 is too much.

Yes the one is looking retarded, I tried moving the dripping and caused some trauma. Hoping she pulls through.
