Which one are you going with? How much less expensive is it? I was looking at this Anden or a Quest.

I would either buy premade tables or make some your self with wheels out of PVC to hold your flood trays and trellis frames. You may also want to look at a quality Dehu, like a quest. Also, the trolmaster environment controller's are super cool. Can control everything from lights to co2.
If buying seeds for 3-500$ per pack. I will drive hours each way to pickup in person as not to worry about shipping. If GLG had a storefront, id take a nice bike ride for pickup.
I think your PH is too low for those temps.
I am not sure what transplanting is going to solve. That thing looks no more than a week or two old, so its not like it is root bound.
how much light are they getting. what is the temp they are in currently and what is the humidity?
do you know the PH of the medium, what PH do you water at and how strong are the nutes?
Growing in Coco. Those are either 5 or 8 gallon pots. I think 5, i dont remember which ones i bought. I have had to feed them twice a day a few times since they went under the LED
just another update. still doing great. i gave them 2 feedings of high nitrogen and burnt a few leaves. other than that. they are goin into flower tonight.
VPD just tells you what humidity to run for a specific temp. If you have good lights and your plants are getting plenty, and co2 is there for them to eat. Running higher temps allows the plants to grow more vigorously.
