Product Description
A-Ok Starter Plugs are for starting seeds and rooting cuttings prior to plugging into larger Gro-Blocks.
The 1.5” size fits perfectly in the Gro-Smart tray as well as all our pre-drilled Gro-Blocks. One advantage of using the Gro-Smart tray is that it elevates the plugs above the waterline and ensures good airflow around the plugs. A-Ok plugs come labeled with instructions in a shrink-wrapped package that fits a standard 10 x 20 tray (flat).
Adjust the pH of water to 5.5. (NO LOWER). Use pH Down or lemon. Check with pH paper or meter.If soaking A-Ok plugs, Macroplugs, or Miniblocks, mix in a little bit of plant food. Then just dip the starter in this pH 5.5 mix and it’s ready for the seed or cutting.
After preparing your starters (A-Ok plugs, round Macroplugs, or Miniblocks) according to instructions in the soak section, plant your seed or cutting (clone). Make sure work area is clean and disease free. Dip cuttings in a rooting hormone beforehand.
Once the you see about 0.5-1″ of root growth below the plug, it is time to transplant. They can go straight into the GRO-BLOCK hole, as they do not have any wrapping on them. Your best bet is to transplant the starter plug into a 3″ or 4″ GRO-BLOCK.WHY? It is much easier to control the moisture level in a 3″-4″ GRO-BLOCK than a larger block. Just wait until the block feels really light before you water. Smaller blocks like these will keep an even moisture level in the entire block. Rule of thumb: water 15 minutes before the block goes dry.If you transplant into bigger blocks: It is essential to keep the upper part of the block moist by misting or watering sparingly.
Has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth
Supports the requirement of the plant in the different plant stages
Once your seedlings have a good rooting structure and are looking strong now is the time for transplanting as the rooting cube will be full of vigorous roots.
5 THCity Stakes included in every order!
