Hey man what's up I got a lot of replies but lemme do a bong rip first
AIght ther we go
Yes, if you get good soil like Fox Farms Ocean Forest (highly recommended) the soil has ph buffers so the ph doesnt change a lot. Checking the pH of your soil (from my understanding) is mainly for people mixing their soil in large patches. Think large vegetable garden with compost, and lime, and stuff in it. That stuff messes with the pH so the gardener needs to add different materials to lower or raise the ph. If your using good soil you really only need to use a pH meter to change your water/nutrient solution. Also I hear those cheap home depots
With the nutrients I use, the tables are in mL/L. I went to Walgreens and went to the little medical devices/applicators section and found an oral syrenge. It looks like a syrenge with a plunger but its just a plastic end. It's used to put medicine in peoples mouth so nothing sharp. Anyway it has measurements in mL so it's really easy to get nutrients/ph right.
uhhh... hahah not really. Probably 3 if you have good reflection and stuff (use mylar). Youll need to like add another 150w or so w to that for flowering for 3 plants, so like 350w-400w 2700k for flowering. They need INTENSE light, and they will get REAL nice with that much wattage. I used 252w 2700k CFL for flowering 2 plants and got like 3 oz cured off 2 plants that were trained.
You want the lights as close as possible without the temps being too hot. If the light is too far away, the plant will stretch to get to the light. You don't want this. A stretched plant has a lot of space between nodes. Nodes are where the buds start forming. So if you have a lot of space between nodes you have airy/light buds. If you keep them close you get rock hard dense nugs. You can also do a lot more with the lights when you have short bushy plants as far as training.
Put your hand plant level, and hold it there for 30 seconds. If your hand becomes uncomfortable it's too hot/close. I recommend (if you haven't) getting fans on either side blowing at the plants/lights. The wind will help the plants grow thick branches that support fat nugs, and it will keep the heat blowing off the lights and off the plants.
So to set up your lights bring it to where your light is just a little too close and work your way up until the hand test shows the distance is good. You will need to be adjusting your lights every few days when the plants start taking off. So make sure your lights are set up where they can be
easily raised and lowered. Set that up as soon as you can and you'll save yourself a LOT of time.
I'm subscribed btw.
I would say that you could get away with only 1 250w blue CFL, personally. I veg using a single 65w 6400k CFL and have no problems at all. I own a 300w 6400k, however my experience has shown zero difference between plants vegged with lots of light and plants vegged with little, hence why I don't bother spending extra money on electric when it doesn't make any difference.
