New Grower Root Stim Questions: GH Rapid Start

[Sunny747]

So all is well. My first auto is doing well and flowering nicely. I just germinated 2 auto fem seeds in 3 gallon smart pots with Roots Organic. I sold one of my kidneys to buy some Rapid Start Root Stimulator I just have a few questions about its use pertaining to autos.

I already hit them with 1 dose.

How early should I begin using this type of product?

How often/frequently should I use it? One a week, every watering, etc? Can I use it along with my veg nutes?

I burned my first plant a little so I am determined to get the nutes right this time. I know it's mostly a matter of preference, but what do you all feel is the best way to use this product?

Thx,
Sunny

What are the ingredients in the rapid start?

Here is the link to the product page. It's alfalfa, barley, willow extracts and what I believe is a very light amount of N,P,K,Fe. From what I have read these products really work well.

I gather that it may be best to wait for first full set of leaves (When growing from seed) and then let your plant have it!

I'd start at a 1/2 or 1/4 recommended dose which I think is a ml a gallon right? Most would use it up until flowering or any time there is root disturbance such as a transplant. Doesn't hurt to run it all the way through to keep your roots healthy the whole time, but your just kinda wasting it toward the end.

Unless you over apply it, I would not worry about nute burn from the root stimulaters.
Auto I usually wait two weeks to give anything though.

Rapid start is a very light dose of nutes to be used on small seedlings to promote root growth.After about two weeks I would start using a higher dose veg nute at 1/2 dose for three weeks than up it to full dose.

I too am about to start a few seeds in Promix BX and plan on using Rapid Start in the seedlings waterings. I think I'll begin with 25% of recommended dosage right from the get go in the sprayer bottle. After two sets of real leaves I will increase to 50% Rapid Start and 25% veg nutes and increase to 100% Rapid Start and 50% veg nutes through the veg cycle. Last time around I waited to the end of week two before giving anything but water as I was told the Promix BX had what was needed until then. Having learned that I was starving those little darlin's I hope to treat the new batch of kids better this time. Does this sound like a good plan or is it too aggressive?

Seems to be working in my grow. I started the RS right away while waiting for Voodoo Juice to arrive by post. See progress here

How are yours coming along?

I used RS on the last couple grows I did before my hiatus and I was using anywhere from 5-8 drops per gallon with positive effects.. The root growth was much better and the quality of the roots was also improved!! I tended to lean towards using it sparingly because I was constantly on the verge of burning..

Good to know, I'll keep an eye on them but only plan on using RS through first 30 days and I am almost there.
Today, day 26, I got a whiff of dank inside the tent and noticed pestles (sp?) on all plants. Good signs me thinks.
