nutrients

hi just bout to grow white widow in a bubble system what nutrients should i use?

GH two part. Floramicro and Florabloom. Mixed at ratios of 1 to 1 during veg and 1 to 2 during bloom works just fine.

I'm also a fan of GH products. I've been using them for about 15 years with great success.

They are every bit as good as AN and more reasonably priced.

Fatman quick question when you say "GH two part. Floramicro and Florabloom. Mixed at ratios of 1 to 1 during veg and 1 to 2 during bloom works just fine. " can you break down that....i am a stoner and cant seem to figure the ratio thing. How much of each are you using again for veg and bloom. Reason im asking is i use that stuff and i have only been following the instructions while you seem to know what you are talking about i would luv your advice!

Do you have a TDS or Conductivity meter? If so you just simply add equal amounts of each to you water in the reservoir until you reach your desired EC or TDS. I do not know at what concentration GH is presently bottling there Floramicro or Florabloom. They do sell a dry preparation and I know it is 1 part Flora Micro to 1 Part Flora Bloom that is formulated to make a X100 concentration.

If it is indeed an x100 concentrtion his means to obtain a EC of 2.9 or a TDS of 2058 you would add 18.8 ml of each per gallon of water. However that is a very strong concentration so I would use about 1/3 that amount or 6.3 ml per gallon of each one.

When budding you would use 12.6 ml of Flora micro and 25.2 ml of Florabloom per each gallon of water.

For young seedling use about 9.4 ml of each per gallon of water.

A 1:1 ratio just means equal parts of each. A 1:1 ratio means use one part Floramicro to each two parts of Florabloom. The seedlings use the same 1:1 ratio but in smaller amounts.

I dont have a TDS or Conductivity meter i just use teaspoons. Actually i just realized i have been using the GH FloraNov veg and bloom. I have some FloraMicro that i have been adding to the bloom nutes. I am just entering my 4th week of flowering and i have so far been using 2 teaspoons of bloom and 1 teaspoon of the micro nutes. I am looking to go ahead and bump up the bloom nutes to 3 teaspoons and 2 teaspoons of the micro....thats per gallon. Any good advice on that.

Also give me a bit of info on Co2 please. My temps in the tent in the day is about 75 and 65 at night and humidity is around 46% on average. I am thinking about going with Co2 but i am thinking of only running it in the middle of the night when the lights are out and the fans go off for say like an hour. I want them fat buds! And i like whereyou say dont worry anbout flusing and run C02 when drying and curing cause the buds continue to grow, i really like that!

I would kick it up to about 2.5 teaspoons of FloraMicro and 5 teaspons of FloraBloom per gallon. Your temps are too low to benefit from CO2. Even then it is only used when the lights are on not at night. CO2 is used when the temperature is over about 75 degrees. It allows growing in temperatures of 90 degrees or more if you have enough light and supply enough ni utrients. Ver few people whi use CO2 allow humidity higher than 40% when budding. I h keep y humidity at 30 to 32% when budding. It requires an airconditioner and a dehun mifier for me as the rooms aresealed room with no ventilation exchange with air outside the room. CO2 is usually one of the last additions to most grow rooms as everything else must be able to operate with maximum high outputs to really gain by using CO2.

Great info man I gave you rep for that. So basically my temp is to low. I have a little fan on my 600w HPS and a duct on it to get that heat out and i also have the the exact fan on the bottom of the tent pushing in cool air so i think i will remove that and put it in my veg closet cause it get hot in there. But wouldnt the humidity increase with more heat in there? I am looking to get a mini dehumidifier soon.

Your humidity is based mainly upon the amount of transpiration your plants are doing. If you are not using CO2 it is doubtful you will have a humidity problem unless your temps go over 80 F. Likely your humidity will actually stay about the same as the transpiration will be lower with less air movement sucking away the moisture will mean the plants transpiration will drop some until the temp goes up. Once the temp goes above around 80 transpiration will increase as the plants try to protect them selves from the heat. However as there will be a shortage of CO2 growth will catually slow. If you are supplying CO2 the humidity will again rise and a dehumidifier should be used instead of an exhaust fan, however with the CO2 being present the plants will grow even faster as they will have all the CO2 they need, and the increased transpiration will allow for faster growth.

Looks like i still got a little research and work to do.
